CDT hfqCT Cirque of the Towers Route

The Cirque of the Towers Route is a 39 km (24-mile) wilderness loop in Wyoming's Wind River Range, United States, gaining approximately 1,463 m (4,800 ft) of elevation over 3 days. Rated moderate to strenuous, it is one of North America's most spectacular high-altitude backpacking circuits, threading a granite amphitheater of 3,700 m spires above a necklace of ice-cold alpine lakes.

About the CDT hfqCT Cirque of the Towers Route

Tucked inside the Popo Agie Wilderness within Bridger-Teton National Forest, the Cirque of the Towers Route is widely considered the crown jewel of Wyoming's Wind River Range. The 39 km loop begins and ends at Big Sandy Trailhead (2,774 m / 9,100 ft), weaving through a chain of pristine alpine lakes and crossing two dramatic mountain passes before arriving at the Cirque itself — a near-vertical granite amphitheater enclosing Lonesome Lake at 3,109 m (10,200 ft).

The defining feature is the ring of granite summits encircling the Cirque: Pingora Peak (3,731 m / 12,241 ft), Wolf's Head (3,716 m / 12,192 ft), Overhanging Tower, Block Tower, and Lizard Head Peak rank among the most photographed alpine towers in North America. The route shares significant mileage with the Continental Divide Trail (CDT), which traverses approximately 200 km through the Wind River Range, keeping to the west side of the Continental Divide — hence the CDT designation in the route name.

Despite its grandeur, the Cirque of the Towers Route requires no permit as of 2026, which is a rarity for a destination of this caliber. What it does demand is solid aerobic fitness, off-trail navigation skill (the Texas Pass section involves cairn-hopping across boulder fields), and a commitment to Leave No Trace principles. Group size is capped at 15 people, campfires are prohibited throughout the wilderness, and camping within 400 m (¼ mile) of Lonesome Lake is not allowed to protect heavily impacted soils.

The Wind River Range occupies a remote corner of southwest Wyoming. Big Sandy Trailhead sits at the end of 27 miles of dirt road, the last 10 of which are rough enough to demand a high-clearance vehicle. This natural filter keeps the backcountry genuinely wild: expect marmots, pikas, high-desert wildflowers, elk, and — increasingly — grizzly bears. Altitude starts at 9,100 ft from the very first step and never drops below that elevation, making acclimatisation a real consideration for hikers arriving from sea level.

The route also suits strong hikers who want to extend the experience. Many parties add side trips from the Cirque to the base of Pingora, or detour to the high terrain around Wind River Peak. If you're planning a challenging multi-day wilderness route in another mountain range, the Theth to Valbona Hike in Albania offers a comparable mountain-to-mountain character at lower altitude, with dramatic passes and remote villages in place of granite spires.

Route Overview & Stages

The classic direction is counter-clockwise: north through gentle lake country on Day 1, then west and south over Texas Pass (3,505 m / 11,500 ft) into the Cirque on Day 2, and east over Jackass Pass (3,277 m / 10,750 ft) back to the trailhead on Day 3. Counter-clockwise gives you the dramatic Texas Pass descent into the Cirque rather than a grinding ascent out of it, and saves the sweeping Jackass Pass panorama for your final morning.

Total distance: 38.6 km (24 miles). Total elevation gain: 1,463 m (4,800 ft). Day 2 is the shortest in distance but the most demanding in navigation and altitude. Afternoon thunderstorms build rapidly in the Wind Rivers — plan to cross both passes before noon.

Highlights & Points of Interest

• Pingora Peak (3,731 m / 12,241 ft) — The Cirque's most iconic tower, a sheer 600 m granite monolith visible from Lonesome Lake. Rock climbers travel from around the world for its classic multi-pitch routes; trekkers can admire the full face from the boulder field below without roping up.
• Texas Pass (3,505 m / 11,500 ft) — The route's highest point and its defining visual payoff. Cresting this off-trail pass, you get your first unobstructed view down into the Cirque's entire granite horseshoe. The 400 m descent to Lonesome Lake is steep and demands careful foot placement on loose talus.
• Lonesome Lake (3,109 m / 10,200 ft) — The still heart of the Cirque, ringed on three sides by vertical granite walls. Camping is permitted above the lake to the southwest in a boulder-dotted plateau that offers some of the most dramatic sleeping locations in North America.
• Wolf's Head (3,716 m / 12,192 ft) — Named for its silhouette against the skyline when viewed from the south. The formation shares a ridgeline with Pingora and is a benchmark for technical alpinists; for trekkers, it defines the imposing western wall of the Cirque.
• Jackass Pass (3,277 m / 10,750 ft) — The eastern gate out of the Cirque, gained on a well-marked trail after departing the boulder field. The view from the pass looks out over the broader Wind River Range and, on clear days, reaches as far as the Wyoming Range to the west.
• Big Sandy Lake (2,957 m / 9,700 ft) — A large turquoise lake on the Day 3 return leg, popular with day hikers and anglers fishing for brook trout. It offers the best open-water swimming of the route — cold, but rewarding in August.
• Mirror Lake — One of several small lakes encountered on the Day 1 approach, offering a perfect surface reflection of surrounding timber and early alpine terrain. It marks the gentle transition from lodgepole pine forest to open tundra.
• Shadow Lake (3,139 m / 10,300 ft) — The standard Day 1 campsite, set in a smaller cirque of its own. This is where the maintained trail ends and off-trail navigation to Texas Pass begins — fill water bottles here before the final cairned ascent.

Best Time to Hike the CDT hfqCT Cirque of the Towers Route

The Cirque of the Towers Route is accessible from mid-July through mid-September, with the exact window depending on annual snowpack. In a heavy snow year, Texas Pass can remain blocked with deep drifts until early August. In a lighter year, late-June approaches are possible, though cold nights and residual ice on north-facing slopes demand full winter sleeping kit.

July offers the longest daylight hours and the wildflowers are at their peak — lupine, Indian paintbrush, and columbine carpet the meadows on the Day 1 approach. The trade-off is mosquitoes and biting midges, which are intense at lower lake elevations in the first half of the month. Waterproof boots and insect-repellent layers are non-negotiable.

Mid-August is the single best month to hike the Cirque of the Towers Route. By mid-August 2026, insect pressure drops sharply, the snowfields on Texas Pass have mostly melted or consolidated into safe névé, and afternoon thunderstorm frequency has not yet reached its September peak. Daytime temperatures at Lonesome Lake average 15–18 °C (59–64 °F); overnight temperatures drop to 2–5 °C (36–41 °F) even in the height of summer, so a sleeping bag rated to -5 °C is the minimum you should carry.

Early September brings cooler, crisper air and dramatically reduced crowds. The first two weeks remain excellent hiking; after mid-September, early snowstorms are possible at pass elevations and mornings can be well below freezing. Check current snowpack data at NRCS SNOTEL stations before any late-season departure.

Avoid US holiday weekends — Fourth of July and Labor Day — if solitude is a priority. The Cirque draws hundreds of campers on peak weekends, with the boulder field above Lonesome Lake sometimes hosting more than 50 tents simultaneously.

Practical Information

Accommodation

There are no huts or staffed mountain refuges on the Cirque of the Towers Route. All nights are spent in free backcountry camping in the Popo Agie Wilderness. The standard 3-day itinerary uses Shadow Lake (Night 1) and the Cirque boulder field above Lonesome Lake (Night 2). Both sites are well-established but strictly regulated: no campfires, camp on durable rock or already-impacted surfaces, bury human waste 60 m from any water source, and pack out all rubbish including food scraps.

For pre- and post-hike accommodation, Pinedale, Wyoming (approximately 70 km / 43 miles north of the trailhead area) is the main service town. Budget motels start at around €90–110 per night; mid-range options run €140–180. Boulder Lake Lodge, closer to the trailhead access road, offers rustic cabin accommodation from approximately €165–200 per night (2026 rates). No reservation system exists for the backcountry campsites — they are strictly first-come, first-served.

Getting There & Back

The nearest commercial airport is Jackson Hole Airport (JAC), approximately 180 km (112 miles) and a 2-hour drive from Big Sandy Trailhead via US-191 South. Salt Lake City International Airport (SLC) is approximately 430 km (267 miles) and 3.5 hours by car, but offers more flight connections and typically lower transatlantic fares from Europe.

From either gateway, take US-191 South to Boulder, Wyoming, then turn east onto Wyoming Highway 353 and follow signs toward Big Sandy Lodge for approximately 27 miles on progressively rougher dirt road. A high-clearance vehicle is strongly recommended; the final 10 miles of rutted track have damaged low-riding sedans. No public transport or commercial shuttle service operates to the trailhead. Carpooling groups and trailhead ride-shares are common — check the Continental Divide Trail Coalition community resources for logistics support and trail condition updates.

Because the route is a loop, you return to the same Big Sandy Trailhead, eliminating any logistical complexity of a point-to-point car shuttle.

Permits & Fees

As of 2026, the Cirque of the Towers Route requires no wilderness permit and no entry fee. The route passes through Popo Agie Wilderness within Bridger-Teton National Forest. Regulations that do apply are strictly enforced:

• Maximum group size: 15 people
• Campfires prohibited throughout the entire Popo Agie Wilderness (stove only)
• Camping prohibited within 400 m (¼ mile) of Lonesome Lake
• Camp at least 60 m from all lakes, streams, and trails
• Bear canister or approved bear hang required (active grizzly bear territory)
• Pack out all waste — no cat-holes for solid waste below treeline in heavily used zones

Gear & Packing List

The Cirque of the Towers Route's combination of high altitude, off-trail navigation, no-fire regulations, and overnight frost demands a well-considered kit. Ultralight principles pay real dividends here — every extra kilogram is felt on the Texas Pass boulder field and during the long Day 1 and Day 3 miles. See our full breakdown of the best ultralight backpacks of 2026 for a comparison of sub-1 kg options suited to exactly this type of high-alpine wilderness trip.

For 3 days at this altitude with overnight temperatures near freezing, a pack volume of 40–55 litres is appropriate. The Hyperlite Mountain Gear 3400 Windrider (55L DCF pack at 765 g) is purpose-built for alpine wilderness trips where weather turns fast. For fast-and-light parties covering the route in 2 days, the trimmer HMG 2400 Windrider (40L / 567 g) carries the essentials with minimal penalty weight. If you prefer a traditional framed pack with better load transfer for heavier bear canister setups, the Osprey Aether 65 distributes weight comfortably across all three days.

Key items for the Cirque route:

• Navigation: Printed USGS 7.5-minute topo map and compass — GPS alone is insufficient for the Texas Pass cairn route in poor visibility or afternoon cloud
• Shelter: Freestanding 3-season tent; the Cirque receives overnight frost as early as late July and afternoon thunderstorms can turn severe
• Sleeping system: Sleeping bag rated to -5 °C minimum; inflatable sleeping pad with R-value ≥ 3.5 for cold ground at 3,100 m
• Water treatment: Filter (Sawyer Squeeze) or UV purifier (Steripen) — water is abundant throughout but requires treatment; giardia is present
• Bear canister: Strongly recommended and increasingly mandated in high-use zones of this active grizzly bear territory
• Insect protection: DEET-based repellent (30%+) and permethrin-treated clothing for July and early August travel
• Sun protection: SPF 50+ sunscreen, UV-B rated sunglasses, and a wide-brim hat — UV intensity above 3,000 m is considerably higher than at sea level
• Nutrition planning: Caloric needs increase at altitude with big mileage. Our guide to how many calories you need hiking a full day can help you calculate food weight vs. energy output before you pack.

Frequently Asked Questions

What is the best time of year to hike the Cirque of the Towers Route?
Mid-July through mid-September is the accessible hiking window, with mid-August being the single best time. By then, most snowfields on Texas Pass have melted or consolidated, insect populations have dropped sharply compared to July, and afternoon thunderstorm frequency is at its seasonal low. Daytime temperatures at the Cirque average a comfortable 15–18 °C and daylight extends to around 20:30 local time, giving plenty of margin for pass crossings.

How difficult is the Cirque of the Towers Route?
The route is rated moderate to strenuous. Most of the 38.6 km runs on well-maintained trail with only moderate grades. The challenging section spans approximately 3 km between Shadow Lake and Lonesome Lake, involving off-trail navigation on cairns across boulder fields and a 366 m ascent to Texas Pass at 3,505 m with no marked path. Experienced off-trail hikers will manage it confidently; those new to navigation at altitude should research this section carefully and carry a compass and paper map.

How many kilometres do you cover per day on this route?
The standard 3-day itinerary averages roughly 12–13 km per day, but days are uneven: Day 1 covers 17.5 km on good trail at a moderate gradient; Day 2 covers only 4.8 km but demands the most effort at altitude with an off-trail approach; Day 3 covers 16.3 km on well-marked path with net elevation loss. Fit parties can condense to 2 days; families or those acclimatising from low elevation should extend to 4 days.

Are there huts or lodges on the route?
No staffed huts or mountain lodges exist along the Cirque of the Towers Route — all accommodation is free backcountry wilderness camping. The nearest roofed accommodation is Boulder Lake Lodge near the trailhead access road (approximately €165–200/night for cabins, 2026 rates) or motels in Pinedale, Wyoming (€90–180/night). Backcountry campsites are first-come, first-served with no reservation system in place.

Do you need a permit to hike the Cirque of the Towers Route?
As of 2026, no permit is required and there is no entry fee to hike or camp on the Cirque of the Towers Route through Popo Agie Wilderness. However, key regulations apply: group size is limited to 15 people, campfires are strictly prohibited throughout, and camping within 400 m of Lonesome Lake is forbidden. These rules can change — always verify current requirements with Bridger-Teton National Forest before your trip.
