Mistymoon Trail

The trail typically begins at West Tensleep Lake. You can find parking at the West Tensleep Lake trailhead, which serves as the primary access point for this route.

The Mistymoon Trail is located within the Cloud Peak Wilderness of the Bighorn National Forest. While there are generally no specific hiking permits required for day use, visitors are expected to adhere to Leave No Trace principles, which includes packing out all solid human waste in the Cloud Peak Wilderness. There are no entrance fees for the Bighorn National Forest itself.

The ideal time to hike is generally from mid-summer to early fall. Earlier in the season, especially due to snowmelt, you might encounter high water levels at creek crossings. Wildflowers are abundant in season, and late summer/early fall offers cooler temperatures and fewer mosquitoes. Be aware that mosquitoes can be quite active, so bug spray is a necessity.

The trail, often identified as Trail 63, offers diverse terrain. You'll traverse through forests, open meadows, and over rocky sections. There are a couple of creek crossings early on. The elevation starts above 9,000 feet and steadily climbs, leading to thinner air. Past Misty Moon Trail, if you continue towards the smaller Fortress Lakes, the path becomes notably steeper and rockier.

The Cloud Peak Wilderness is rich in wildlife. Hikers frequently spot moose, including bull moose, often around the lakeshores. You may also encounter deer, black bears, and various bird species. Always maintain a safe distance and never feed wildlife.

The route is celebrated for its stunning views and pristine high-altitude lakes. Key highlights include West Tensleep Lake at the start, Lake Helen (often considered the most picturesque), Lake Marion, and finally Mistymoon Lake itself. From Lake Helen, you can often see Cloud Peak, the highest point in the Bighorn Mountains. Scenic meadows and creek bottoms also add to the beauty.

Yes, dogs are generally allowed on the Mistymoon Trail within the Cloud Peak Wilderness. However, they must be kept on a leash to protect wildlife and ensure a pleasant experience for all hikers. Please remember to pack out all pet waste.

Given the high starting elevation above 9,000 feet and the steady climb, hikers should be aware of the potential for altitude sickness. Symptoms can include headaches, dizziness, or nausea. It's beneficial to acclimatize by spending a night at a lower elevation before your hike. Stay hydrated and listen to your body.

Yes, the route also passes through sections of the Trail 065 (Lost Twin Lakes Trail) and the Trail 064. These intersections can offer options for longer excursions or alternative routes within the Cloud Peak Wilderness.

Beyond standard hiking essentials, it's crucial to bring plenty of water, layers of clothing for changing weather, and sturdy hiking boots. Due to the prevalence of mosquitoes, especially during certain seasons, a strong insect repellent is a necessity. Also, remember to bring a wag bag or other means to pack out all solid human waste, as required in the Cloud Peak Wilderness.

The majority of the hike up to Mistymoon Lake is considered moderate in difficulty, involving a gradual 7-mile climb. While not overly technical, the high elevation and distance require good physical fitness. Beginners with some hiking experience and proper preparation for altitude can enjoy it, but those new to hiking might find it challenging. Extending beyond Mistymoon Lake to areas like Fortress Lakes significantly increases the difficulty.
