Ruta-01 de Senderismo. Ferrocarril

The Ruta-01 de Senderismo Ferrocarril is a 165 km point-to-point rail trail in Paraguay, following the disused Ferrocarril Carlos Antonio López line between the stations of Villarrica and Coronel Bogado. With only about 350 m of cumulative elevation gain over roughly 8 days, it is rated easy to moderate, ideal for walkers who want history, gentle gradients and rural Guaraní landscapes.

About the Ruta-01 de Senderismo. Ferrocarril

The Ruta-01 de Senderismo Ferrocarril is a long-distance walking route that traces the trackbed and right-of-way of Paraguay’s first railway, the Ferrocarril Carlos Antonio López. The full railway, inaugurated on 21 October 1861 as the Ferrocarril Central del Paraguay, once ran roughly 370 km from Asunción to Encarnación. The walking route described here covers the southern interior section between the Estación de Villarrica and the Estación de Coronel Bogado, a corridor of approximately 165 km through the departments of Guairá, Caazapá and Itapúa.

This is one of South America’s most distinctive heritage trails. The line was engineered by British contractors, including George Paddison, and financed directly by President Carlos Antonio López, making it the second oldest railway on the continent. Regular passenger service ceased in 2009, leaving stations, water towers, level crossings and bridges scattered along a corridor that walkers now follow on foot. Because it is registered as part of the International Walking Network (IWN), the route carries the same waymarking philosophy as Europe’s great long-distance paths, even though much of it runs through quiet farmland and subtropical forest rather than mountains.

The walking is overwhelmingly flat. Railways were graded for locomotives, so gradients rarely exceed two or three percent, and the cumulative climb across the entire 165 km is only around 350 m. That makes the Ruta-01 a forgiving introduction to multi-day trekking, where the daily challenge is heat, distance and navigation rather than ascent. If you are planning your fuel and pacing for long flat days, our guide to how many calories you need hiking a full day is a useful companion before you commit to eight days on the trackbed.

The trail passes through the heart of Guaraní-speaking Paraguay. Towns such as Sapucaí and Villarrica grew up around the railway workshops, and you will hear Guaraní spoken alongside Spanish in nearly every village. Expect red dirt roads, yerba mate plantations, sugarcane fields and the steady rhythm of a route that was, for nearly 150 years, the country’s economic spine.

What sets the Ruta-01 apart from typical wilderness treks is its layered history. The original line used a broad 1,676 mm gauge before being standardised to 1,435 mm to connect with Argentine railways across the river at Posadas. Wood-burning steam locomotives ran here into the 21st century, making this one of the last working steam railways on earth before the final regular service stopped in 2009. Walking the corridor today is part trek, part open-air industrial-heritage museum, with rusting water cranes, turntables and station platforms marking nearly every former stop. The corridor was also a strategic artery during the War of the Triple Alliance (1864–1870), and several stations still bear scars and commemorative plaques from that conflict.

Route Overview & Stages

The route is best broken into eight walking days, each anchored on a former station or a town with food and lodging. Distances below are approximate, based on the railway alignment and connecting rural roads between Villarrica and Coronel Bogado.

Total distance is approximately 165 km with around 350 m of cumulative ascent. Strong walkers can compress the route into six longer days, while those wanting time for village stops and railway photography may prefer to add a rest day in Caazapá.

Highlights & Points of Interest

• Estación de Villarrica — the route’s northern trailhead, a handsome brick station in the cultural capital of Guairá, surrounded by yerba mate and tobacco country.
• Villarrica Cathedral — the Catedral del Espíritu Santo, an early stop where many walkers stock up on supplies before heading south.
• Sanctuary of the Virgen de Itapé — one of Paraguay’s most important pilgrimage sites, drawing tens of thousands of visitors each December.
• Caazapá old town — founded in 1607, home to a Franciscan church and one of the oldest reducción settlements in the region.
• Caazapá forest reserve — remnant Atlantic Forest with toucans, howler monkeys and abundant birdlife along the trail’s middle stages.
• San Juan Nepomuceno — a lively market town and the natural midpoint resupply, with the best food options between the two terminal stations.
• Restored level crossings near General Artigas — original cast-iron signage and timber sleepers that survived the line’s 2009 closure.
• Estación de Coronel Bogado — the southern terminus in Itapúa, a short hop from the colonial circuit of Jesuit missions around Encarnación.

Best Time to Hike the Ruta-01 de Senderismo. Ferrocarril

Paraguay’s interior has a humid subtropical climate, and timing matters more here than elevation ever will. The Paraguayan winter, from May to August, is the dry, cooler season and by far the most comfortable window for walking. Daytime highs sit around 22–26°C, nights drop to a pleasant 8–12°C, and the red-earth trackbed stays firm rather than turning to the sticky mud that follows summer storms.

As of 2026, July is the single best month to hike the Ruta-01. It delivers the lowest rainfall of the year, minimal mosquito activity and clear skies that make the long flat stages genuinely enjoyable. June and August are close seconds, with slightly higher chances of a passing cold front (a surazo) that can bring a day or two of grey drizzle.

Avoid the December to February summer if you can. Temperatures regularly exceed 38°C with crushing humidity, afternoon thunderstorms flood low sections of the trackbed, and biting insects are relentless near the forest reserves. If summer is your only option, walk before 10am, rest through the midday heat and carry far more water than the cooler months demand.

Practical Information

Accommodation

This is not a hut-to-hut trail. Lodging is found in the towns that grew up around the old stations, and you should plan each day to finish where beds exist. Simple hospedajes and family guesthouses in Villarrica, Caazapá and San Juan Nepomuceno cost roughly €12–22 per night for a private room. Mid-range hotels in Villarrica and Coronel Bogado run €25–40. Camping is possible on the trackbed and in fields with a landowner’s permission, often free or for a small €3–5 courtesy fee; there are no formal campgrounds, so a self-contained shelter and water plan are essential. Budget around €20 per day for accommodation and food combined if you mix guesthouses with the occasional wild camp.

Getting There & Back

The nearest major airport is Silvio Pettirossi International (ASU) in Asunción, about 175 km northwest of Villarrica. From Asunción’s Terminal de Ómnibus, frequent buses reach Villarrica in roughly 3 to 3.5 hours. At the southern end, Coronel Bogado sits on Ruta 1 with regular buses to Encarnación in about 1 hour, from where you can connect back to Asunción (around 5 hours) or cross into Posadas, Argentina. Allow a full travel day on either side of the walk. Long-distance buses in Paraguay are inexpensive, with the Asunción to Villarrica fare costing roughly €6 and the Encarnación connection around €2, so reaching the trail rarely strains a budget.

Once on the route, local colectivo buses link most of the section towns, which is useful if weather or fatigue forces you to skip a stage. Services are frequent on the busier southern stretch around General Artigas and Coronel Bogado, and sparser through the forested middle, so plan resupply and exit points before you set off rather than relying on flagging down transport mid-stage.

Permits & Fees

No permit is required to walk the Ruta-01, and there is no entrance fee for the trail itself. The disused right-of-way is administered by the national rail company, and walkers should respect any fenced or active maintenance sections. Where the route crosses private farmland, a friendly request in Spanish or Guaraní is almost always granted. For current railway corridor status, consult the operator FEPASA, and for regional travel advice and town services, the national tourism authority SENATUR publishes up-to-date guidance.

Gear & Packing List

Because the Ruta-01 is flat and town-supported, you can travel light, but heat, sun exposure and limited shade dictate your kit. A pack in the 35–50 litre range is ample. The Abisko Hike 35 suits walkers who resupply daily in towns, while those carrying a tent and several days of food on the forested middle stages will prefer the volume of the Arc Haul Ultra 60L or the ventilated Atmos AG 50. The Arc Haul’s suspended mesh back is a real asset in subtropical humidity.

Prioritise sun protection: a wide-brim hat, long-sleeve sun shirt, UV-blocking sunglasses and high-SPF sunscreen, since the open trackbed offers little cover for hours at a time. Carry a minimum 3 litres of water capacity, a reliable filter for stream and tank water, and electrolyte tablets. Lightweight trail runners outperform stiff boots on the firm dirt surface.

Frequently Asked Questions

When is the best time to hike the Ruta-01 de Senderismo Ferrocarril?
July is the best month, falling in Paraguay’s dry winter season with daytime highs near 24°C, cool nights and the year’s lowest rainfall. June and August are also excellent. Avoid December to February, when temperatures top 38°C, humidity is intense, thunderstorms flood the trackbed and biting insects are at their worst near the forest reserves.

How difficult is the trail?
The Ruta-01 is rated easy to moderate. It follows a former railway, so gradients almost never exceed three percent and total ascent across 165 km is only around 350 m. The real challenges are heat, sun exposure on open sections, navigation along faint trackbed and daily distances of 18–24 km rather than any steep or technical climbing.

How many kilometres per day should I plan?
Most walkers cover 18 to 24 km per day, completing the full route in about eight days between Villarrica and Coronel Bogado. Because the terrain is flat, fit hikers can stretch to 27–30 km and finish in six days. Pacing is usually set by where lodging and resupply exist rather than by terrain difficulty.

Where can I sleep along the route?
There are no trail huts. You sleep in towns that grew around the old stations — Villarrica, Caazapá, San Juan Nepomuceno and Coronel Bogado — using family guesthouses and small hotels from about €12 to €40 a night. Wild camping on the trackbed or in fields is possible with a landowner’s permission, usually free or a small courtesy fee.

Do I need a permit or pay any fees?
No permit is required and the trail itself is free to walk. The disused corridor is overseen by the national rail company FEPASA, so respect any fenced or active maintenance sections. Where the route crosses private farmland, a polite request in Spanish or Guaraní is nearly always welcomed, and there are no formal entrance gates along the 165 km.
