The primary trailhead for this route is typically accessed from the Stillwater Reservoir area. Parking is available at the Stillwater Reservoir Trailhead. It's advisable to arrive early, especially on weekends, as parking can fill up quickly due to the trail's popularity.
This trail is rated as difficult. While the initial sections from Stillwater Reservoir are relatively easy, the route involves significant elevation gain over talus slopes. The most challenging part is the Devils Causeway itself, a narrow land bridge that can be as little as 3 to 4 feet wide with significant drop-offs on either side. It requires a good head for heights and should be avoided if conditions are wet, windy, or if bad weather is approaching.
The terrain varies considerably. You'll start through forested sections and open meadows, gradually transitioning to rough and rugged alpine environments. Expect talus slopes (broken rock) and steep ascents as you gain elevation. Beyond the Devils Causeway, the route may continue across flat, rolling alpine tundra if you're doing a longer loop.
Hikers can expect spectacular scenery throughout. Key highlights include the stunning View of Little Trappers Lake, the impressive Chinese Wall (a mile-long mesa), and magnificent views of the surrounding Routt and White River National Forests. The Devils Causeway itself offers sweeping views across the high plateau of the Flat Tops Wilderness.
Yes, the route intersects with several other trails. You'll find sections of the Little Trappers Trail, Bear River Trail, Chinese Wall Trail, East Fork Trail, and Carhart Trail along the way. The Devils Causeway Loop Trail is a popular option for extending the hike.
The best time to hike this trail is typically from late July through early September. This period offers the most favorable weather conditions, with wildflowers often in bloom in the meadows. Before late July, snow can still be present at higher elevations, and after early September, weather can become unpredictable with early snowfalls.
Yes, dogs are generally allowed on this trail within the Flat Tops Wilderness. However, they must be kept on a leash to protect wildlife and ensure a pleasant experience for all hikers. Be aware that the narrow and exposed Devils Causeway might be challenging or unsafe for some dogs, especially larger ones or those not accustomed to heights.
No, there are typically no permits required or entrance fees to access the Flat Tops Wilderness Area for day hiking. However, always check the latest regulations with the US Forest Service (usda.gov) before your trip, especially if planning an overnight stay or group activity, as rules can change.
The Flat Tops Wilderness is rich in wildlife. Hikers often spot elk, especially in the meadows during dawn or dusk. You might also encounter smaller mammals like marmots and pikas in the rocky alpine areas, as well as various bird species. Remember to observe wildlife from a distance and never feed them.
This is a long and strenuous hike. The full route, which is nearly 29 km (18 miles) long, typically takes around 8 to 9 hours to complete. This duration can vary significantly based on your fitness level, the number of stops you make, and whether you choose to do a shorter out-and-back or a longer loop.
Given the trail's difficulty and alpine environment, essential items include plenty of water, high-energy snacks, sturdy hiking boots, and layers of clothing suitable for changing weather conditions. Sun protection (hat, sunscreen) is crucial due to high elevation exposure. A map and compass or GPS device are also highly recommended, as is a first-aid kit. Trekking poles can be very helpful on the steep and rocky sections.
