Greater Patagonian Trail Section 35: Parque Patagonia

Greater Patagonian Trail Section 35 is a point-to-point wilderness trail in Parque Patagonia, Chile's Aysén Region. Exact distance and elevation gain are not officially published for this section. The terrain spans exposed Patagonian steppe, flamingo-edged lakes, and the rewilded conservation lands of Parque Patagonia. Rated advanced, it forms part of the International Walking Network — demanding full self-sufficiency and GPS navigation.

About the Greater Patagonian Trail Section 35: Parque Patagonia

The Greater Patagonian Trail (GPT) is one of the world's most ambitious and least-developed long-distance hiking routes. Stretching roughly 2,250 km from the outskirts of Santiago southward through Chilean and Argentine Patagonia, it has earned recognition on the International Walking Network (IWN) as a route of global significance. Section 35 passes through the heart of Parque Patagonia — a landscape forged by wind, ice, and millennia of glacial activity in one of the Southern Hemisphere's most intact temperate ecosystems.

Parque Patagonia sits in the remote Aysén Region of Chilean Patagonia, bordered to the east by Argentina and to the north by Reserva Nacional Lago Jeinimeni. The park was established largely through the philanthropic land purchases of Tompkins Conservation and was incorporated into Chile's national park system in 2018. It protects an extraordinary mosaic of Patagonian steppe, native lenga beech forest, glacial wetlands, and mountain ridgelines where wildlife populations — including guanaco, puma, and Andean condor — have rebounded dramatically since livestock fencing was removed.

Section 35 does not follow a single marked trail. Instead it threads together a network of unmaintained paths, livestock tracks, and road X-753 — a lightly-trafficked dirt track through exposed, flat-to-gently-rolling steppe. This is quintessential GPT terrain: no signage, no rescue infrastructure, and long stretches between reliable water sources. The section also crosses the boundary of Reserva Nacional Lago Jeinimeni, where a staffed ranger station marks the transition from open range to managed conservation land and is the first official contact point on the route.

The GPT as a whole is managed collaboratively by its hiker community, with all documentation shared openly on the WikiExplora platform and kept current by participants who have completed each section. This makes Section 35 a genuine wilderness undertaking: the trail exists because people keep documenting it, not because an agency has built and maintained it. Expect route conditions to change season to season, and always download the most current GPT tracks before departure.

Route Overview & Stages

Exact stage distances for Section 35 are not officially published by the GPT. The route is best understood as a progression through three distinct terrain zones: open steppe on the approach, the Lago Jeinimeni lakeshore corridor, and the interior of Parque Patagonia proper. The table below reflects verified waypoints and documented route character; daily distances vary depending on water availability, prevailing wind, and the specific track variant chosen.

Direction recommendation: Walk Section 35 north-to-south if your GPT direction brings you from the Cochrane area (Section 34) into Parque Patagonia. This natural flow places you at the Jeinimeni ranger station in the morning — rangers require your first night to be spent at Refugio Valle Hermoso, roughly 15 km inside the reserve, which works best as a morning objective rather than a forced late-afternoon push after a long day. Arriving at the station past 15:00 with full packs and deteriorating weather is avoidable with this approach.

Highlights & Points of Interest

• Reserva Nacional Lago Jeinimeni — A protected reserve adjacent to Parque Patagonia, with a turquoise glacial lake framed by striking pink and red sedimentary rock formations. The staffed ranger station at the reserve entrance is the first official checkpoint on this section and provides filtered water access.
• Flamingo Wetlands (Steppe Approach) — Shallow saline lagoons along the road X-753 approach regularly host Chilean flamingos (Phoenicopterus chilensis). The contrast of pink birds against the ochre and brown steppe is one of Section 35's most unexpected rewards. Early morning — before Patagonian winds build — offers the calmest conditions for wildlife observation.
• Refugio Valle Hermoso — The first designated overnight stop inside the Jeinimeni reserve, approximately 15 km from the section's entry at the reserve boundary. Rangers assign this as the mandatory first-night camp for hikers entering the reserve. The Valle Hermoso setting is sheltered by valley walls and offers one of the section's calmest camping environments.
• Parque Patagonia Core Conservation Zone — Donated to Chile by Tompkins Conservation and formally incorporated into the CONAF national park network in 2018, this conservation area represents one of the most significant rewilding projects in South America. The return of guanacos, pumas, and Andean condors to pre-ranching densities is visible and documented within the park.
• Guanaco Herds — Lama guanicoe have rebounded dramatically inside Parque Patagonia since livestock fencing was systematically removed. Sections of steppe within the park hold herds of dozens of animals — a genuine wildlife spectacle with the Andes rising behind them.
• Andean Condor (Vultur gryphus) — The skies above Parque Patagonia offer among the most reliable condor sightings in Patagonia. With a wingspan reaching 3.1 m, these birds thermal above valley edges and rocky outcrops. Mid-morning, once thermals have developed, is prime time to scan the ridgelines. Section 35's open terrain means sightlines are rarely obstructed.
• Road X-753 Steppe Traverse — Far from being a compromise, the initial road walk through exposed high desert is one of the section's defining experiences: an immense sky, absolute solitude, and the visceral sense of entering a landscape that infrastructure has largely bypassed. Wind speeds on this exposed stretch can exceed 70 km/h — factoring this into your daily start time is essential.
• Lenga Beech Transition Zone — As the route drops into the Parque Patagonia interior, open steppe gives way to lenga beech (Nothofagus pumilio) woodland. This ecotone — where two distinct ecosystems meet — marks the transition to moister, more sheltered terrain and signals the final approach to the section's southern exit point.

Best Time to Hike the Greater Patagonian Trail Section 35: Parque Patagonia

The viable window for this section is narrow. Patagonian weather is severe for most of the year, and Section 35 passes through exposed steppe where sustained wind and cold can turn dangerous without warning.

November to March constitutes the entire austral summer hiking window. Within this period, November is the single best month: daylight runs 16–17 hours, vegetation is freshest, flamingos are active in the steppe wetlands, river levels are manageable before peak snowmelt, and foot traffic on the main Parque Patagonia day-trails is low compared with January. Conditions as of 2026 at Parque Patagonia mirror this historical pattern — rangers confirm the summer season opens reliably by early November.

December is also excellent and only marginally busier. January and February bring the strongest westerly winds — gusts above 80 km/h are common on exposed steppe sections — and the highest daytime temperatures (15–22 °C). The temperature swings between midday and overnight can exceed 20 degrees in February, which demands layering versatility in your pack.

March remains viable but tightens logistics fast. Daylight drops by roughly 2 minutes per day from mid-February onward, the first frosts arrive at altitude, and the Jeinimeni ranger station reduces operating hours. Do not plan late-March departures for Section 35 without confirmed emergency exit options and cold-weather gear for sub-zero overnight temperatures.

April through October: do not attempt this section. Snowfall, ice, and sustained winds above 100 km/h make navigation and safe camping untenable on open steppe. The Jeinimeni reserve ranger station closes seasonally and cannot be relied upon for any support outside the summer window.

Practical Information

Accommodation

Infrastructure on Section 35 is minimal. The GPT does not assume hut-to-hut hiking; wild camping is the default mode for the majority of the route.

• Refugio Valle Hermoso — Basic shelter inside the Jeinimeni reserve, approximately 15 km from the reserve boundary. Rangers require GPT hikers to spend their first night here. No additional cost beyond the park entrance fee, but berths are limited. Carry a tent regardless — the refugio is not a reliable shelter substitute.
• Wild Camping (Parque Patagonia) — CONAF-designated camping areas are located within the park. Fees are typically in the range of CLP 3,000–6,000 (approximately €3–6) per person per night as of 2026. Always confirm current fees at the Cochrane CONAF office or online before entering the park, as fees are updated annually.
• Cochrane (Pre/Post-Section Town Base) — The nearest town for the northern approach. Hostal and residencial accommodation is available from approximately CLP 20,000–35,000 (roughly €20–35) per night. Cochrane has a supermarket, basic resupply options for dried food, and the CONAF regional office where current park entry conditions can be confirmed.

Getting There & Back

Section 35 sits in one of the most remote regions of Chilean Patagonia. Access requires careful logistical planning, and transport frequency drops sharply outside the December–February peak.

• By air: Balmaceda Airport (BBA), near Coyhaique, is the nearest commercial airport — approximately 300 km north of Cochrane. LATAM Chile and Sky Airline operate flights from Santiago (SCL). The bus journey from Balmaceda to Cochrane along the Carretera Austral (Ruta 7) takes approximately 6–7 hours.
• By bus: Several operators run the Coyhaique–Cochrane route on the Carretera Austral, including Bus Acuario and Turbus. Frequency reduces significantly in November and March compared to the January peak — book seats in advance for any departure outside December–February.
• Exit logistics: As a point-to-point route, Section 35 requires either pre-arranged vehicle pickup from the southern exit point or a direct continuation onto Section 36. The southern terminus is not served by scheduled public transport. Confirm your exit strategy via the GPT community documentation on WikiExplora before departure — conditions and access roads change.

Permits & Fees

• Reserva Nacional Lago Jeinimeni entry fee: CLP 3,000 per person (approximately €3). Paid in cash at the ranger station at the reserve boundary. Card payment is not available.
• Mandatory registration: Required at the Jeinimeni ranger station. Rangers log hikers' details, assign the Refugio Valle Hermoso first-night requirement, and note your planned exit. This registration functions as a basic safety check for a route with no other oversight.
• Parque Patagonia CONAF fee: A separate entry fee applies for the park interior. Check current rates at CONAF's official website before departure, as fees are revised annually and may differ from previous hikers' reports.
• GPT route files: No permit is required to access GPT tracks, but registering with the WikiExplora community is strongly recommended — it provides access to the most current route notes, track updates, and water source information contributed by recent hikers.

Gear & Packing List

Section 35 demands fully self-sufficient packing. The steppe approach offers no resupply and water sources can be widely spaced; a 4–7 day food carry is standard depending on your pace and chosen route variant. Planning your calorie needs before a remote multi-day carry is worth doing carefully — the guide on how many calories you need hiking a full day covers the calculation in practical terms.

Pack selection is one of the most consequential decisions for any GPT section. The route combines road walking, cross-country steppe navigation, and — for packraft-equipped hikers — optional water stages. Weight compounds over weeks of hiking:

• Hyperlite Mountain Gear 3400 Windrider (680 g) — The most frequently cited ultralight choice among GPT thru-hikers. Dyneema Composite Fabric construction handles sustained Patagonian rain well, and the 3400 capacity accommodates a 5–7 day food carry without maxing the pack volume. At 680 g it keeps base weight low enough to manage the long daily distances the steppe sections demand.
• Zpacks Arc Haul Ultra 40L (540 g) — A competitive ultralight alternative at 540 g. The carbon fibre framesheet provides load transfer uncommon at this weight. The 40 L capacity is tight for food carries beyond 5 days; for sections with longer resupply gaps, consider a larger pack or supplementary dry bags.
• Osprey Aether 65 (2210 g) — The choice for hikers who prioritise load-carrying comfort over pack weight, or who are carrying a packraft setup. The 2210 g frame handles heavier loads on the physically demanding southern sections where pack contents run heavy.
• Deuter Aircontact Lite 45+10 (1570 g) — A reliable midweight option at 1570 g. The extendable 10 L lid is useful when food carries push beyond base capacity, and the back ventilation system manages the high-exertion steppe road-walking sections. The 2026 ultralight backpack roundup compares several of these packs in detail if you are still deciding on the right weight-to-capacity balance.

Beyond the pack, Patagonian-specific essentials for Section 35 include: a four-season tent rated for winds above 80 km/h (standard dome designs fail — use a low-profile freestanding tent with multiple guylines staked at 45-degree angles), a GPS device loaded with current GPT tracks downloaded from WikiExplora (non-negotiable — there is no reliable navigation without them), a water filter capable of processing turbid steppe sources, a wind-proof insulated layer for all-day wear, and cash in Chilean pesos for ranger station fees. Trekking poles are strongly recommended for the lenga beech section where root networks and river crossings demand balance support under a loaded pack.

If Section 35 through Parque Patagonia draws you in — immense open landscapes, minimal infrastructure, and authentic wilderness navigation — the following GPT sections offer comparable or complementary experiences across central and southern Chile. Each shares the GPT's defining character: self-reliance over convenience, terrain over tourist infrastructure.

• Greater Patagonian Trail Section 6: Volcán Descabezado (112 km, Chile) — Volcanic terrain north of Section 35, with a high-altitude traverse beneath Volcán Descabezado Grande and extended cross-country navigation through the pre-Andean zone.
• Greater Patagonian Trail Section 8: Volcán Chillán (128 km, Chile) — One of the longer GPT sections, combining active volcanic terrain near the Chillán complex with river valleys and indigenous Pehuenche territory across 128 km of varied backcountry.
• Greater Patagonian Trail Section 9: Volcán Antuco (49 km, Chile) — A tighter, more accessible section centred on the Antuco stratovolcano and Laguna del Laja — a viable entry point to GPT terrain for hikers new to the network.
• Greater Patagonian Trail Section 10: Laguna El Barco (48 km, Chile) — Remote lake and valley country with a compact 48 km distance that rewards slower, more exploratory pacing through pristine backcountry.
• Greater Patagonian Trail Section 11: Cerro Dedos (33 km, Chile) — The shortest of this group at 33 km and a good introduction to GPT navigation style, with striking granite formations near Cerro Dedos and lower logistical complexity than the longer southern sections.

For a very different multi-day wilderness experience outside South America, the Theth to Valbona route in Albania offers a similarly remote, infrastructure-light traverse — though in the entirely different setting of the Albanian Alps.

Frequently Asked Questions

What is the best time of year to hike Greater Patagonian Trail Section 35?

November is the single best month. The full austral summer window runs November through March, but November combines maximum daylight (up to 17 hours), lower average wind speeds than January–February, active flamingo populations in the steppe wetlands, and manageable river levels before peak snowmelt arrives. December is the close second; March is possible but brings early frosts and rapidly shortening days. April through October is not viable.

How difficult is GPT Section 35: Parque Patagonia?

This section is rated advanced. Difficulty derives less from technical terrain and more from navigation demands: there is no trail signage, GPS proficiency is mandatory, and water sources on the steppe approach can be widely spaced. River crossings in the Parque Patagonia interior can reach thigh depth during spring snowmelt. Solo hiking experience on unmarked wilderness routes, multi-day self-sufficiency skills, and comfort with route-finding from GPS tracks are all prerequisites.

How many kilometres can I expect to cover per day on this section?

Daily distances on GPT Section 35 typically fall between 15 and 25 km depending on terrain, wind, and the specific route variant walked. The mandatory first night at Refugio Valle Hermoso — approximately 15 km from the Jeinimeni reserve entry — effectively sets the pace for the opening day. The flat steppe road-walking allows faster progress; cross-country terrain and the lenga beech interior section are slower due to navigation demands and underfoot conditions.

What accommodation is available on GPT Section 35?

Accommodation infrastructure is minimal by design. The one designated shelter is Refugio Valle Hermoso, assigned as the mandatory first overnight stop inside the Jeinimeni reserve. Beyond this point, CONAF-designated camping areas exist within Parque Patagonia for approximately CLP 3,000–6,000 per person per night (roughly €3–6 as of 2026). Wild camping outside designated areas is not permitted within the park boundaries. Always carry a tent — refugio berths are limited and not guaranteed.

Do I need a permit to hike GPT Section 35?

No advance permit is required, but mandatory registration and a CLP 3,000 entry fee (approximately €3) must be paid at the Reserva Nacional Lago Jeinimeni ranger station. A separate CONAF fee applies for the Parque Patagonia interior section. Carry cash in Chilean pesos — card payment is not available at remote ranger stations. Fees and operating seasons are confirmed annually; check current details at the CONAF Cochrane office before beginning the section.
