Really fun hike that can be made short or long. Nice variety from mountains and lakes

Snowbank Lake is a hidden gem in the RMNP. Sitting at the base of Mount Alice and Pilot Mountain, with views to Chief Heads Peak, the lake has a small glacier with snowbanks that last for the entire year. It is better to do this hike from June to September to avoid the snow fields along the trail and slippery rocks from Lions Lake to Snowbank Lake.

This is a series of at least three lakes hidden in the Wild Basin area. The Lion Lakes are surrounded by open areas, pine tree lines, and features a rocky landscape. The area has many places to explore, offering different spots to have a picnic and enjoy quiet moments, appreciating the wild nature around. The trail to the lakes starts at Wild Basin trailhead, going through the forest and small meadow areas. It is not a technical trail, but is quite long, and it can have snow along it for most of the year; it is better to ask the rangers about the trail conditions, and in any case it’s good to have some waterproof hiking shoes and a pole to check what is beneath the snow.

Be sure to take the side trail here that gives you views of the falls. There are a number of small rushing waterfalls up this portion of the trail.

Barker Reservoir is at the top of Boulder Canyon Drive just outside of the small town of Nederland. This is a great place to catch your breath after the long climb up the canyon and snap some photos.

Located in Boulder Canyon and just a few minutes walk from the trailhead parking, Boulder Falls is a surprisingly roaring waterfall on North Boulder Creek. The falls are accessible most times of the year, and there is plenty of room for viewing even on more crowded days.
