Hiking

Embark on an easy hike along the Fairy Lake Access Trail, a gentle route that takes you through a forested bowl at the base of Sacagawea Peak. This pleasant 1.8-mile (3.0 km) journey involves a minimal elevation gain of just 63 feet (19 metres), making it suitable for most hikers. You can expect to complete the trail in about 1 hour, winding your way past silver firs as you descend towards the pristine alpine waters. The path eventually leads you to Fairy Lake, where you can enjoy views of Bridger Pass and the tranquil surroundings.

Before you head out, be aware that accessing Fairy Lake requires navigating Forest Road #74, which is known for being quite rough. A high-clearance vehicle is often necessary for this road, and it is not recommended for RVs or any towed units. The surface can also become slippery when wet, so exercise caution. During the winter months, the road typically closes beyond the ranch gate, making the trail inaccessible until spring.

Fairy Lake itself is a stunning alpine gem, nestled within the Custer Gallatin National Forest. It serves as a popular destination for those looking to picnic, fish, or even take a refreshing swim in its clear waters. The trail offers a peaceful escape into nature, providing a chance to connect with the unique ecosystem surrounding this beautiful mountain lake.
