Devils Causeway Loop

The Devils Causeway Loop is generally considered an intermediate to difficult hike, often rated around 7 or 8 out of 10. It involves significant elevation gain, steep sections with switchbacks and talus slopes, and the particularly challenging crossing of the narrow Devils Causeway itself.

The Devils Causeway is a unique, narrow land bridge, sometimes as little as 3 to 4 feet wide and about 50 feet long, with sheer drops of 60 to 80 feet on either side. This exposed section requires excellent footing and can be a significant psychological hurdle, especially for those with a fear of heights. Many hikers opt to crawl across it.

The hike typically begins at Stillwater Reservoir, which serves as the primary trailhead. Parking is available at the reservoir, but it can fill up quickly during peak season. Arriving early is recommended to secure a spot.

The trail is usually accessible from late June to early September. This window offers the best chance for clear conditions, but hikers should always be prepared for rapidly changing mountain weather, including afternoon thunderstorms, which can make exposed sections dangerous.

As the Devils Causeway Loop is located within the Flat Tops Wilderness Area, there are typically no permits required for day hiking, nor are there entrance fees. However, always check the latest regulations from the US Forest Service before your trip, especially if planning an overnight stay.

The trail offers diverse and spectacular scenery, transitioning from lush greenery near the Bear River and wildflower-filled meadows to high alpine landscapes. You'll encounter pristine alpine lakes like Little Causeway Lake and Mosquito Lake, and enjoy panoramic views of the Flat Tops' unique basaltic domes. The highlight is undoubtedly the dramatic Devils Causeway itself.

The most notable feature is the Devils Causeway, a unique geological formation. The entire Devils Causeway Loop Trail offers stunning views of the Flat Tops Wilderness, including high alpine meadows, volcanic cliffs, and several beautiful lakes.

Given its intermediate to difficult rating, significant elevation gain, and the challenging Devils Causeway crossing, this loop is generally not recommended for beginners or families with young children. Hikers should have prior experience with strenuous mountain trails and be comfortable with heights.

Essential items include plenty of water, high-energy snacks, layers of clothing for rapidly changing weather, rain gear, sun protection (hat, sunscreen), a map and compass or GPS device, a first-aid kit, and sturdy hiking boots. Trekking poles can be very helpful for the steep ascents and descents.
