(Trailhead is shuttle bus accessible.) Considered by many the best alpine lake hike in the book, and for good reason. This hanging valley off Glacier Gorge is truly a magical place, but the approach is difficult at best. A nine mile round trip jaunt from the Glacier Gorge Trailhead on Bear Lake Road the last mile to the lakes leaves the main trail at an easily missed turnoff before climbing an extremely steep slope. If you are unable to find the turn off do not feel bad about continuing on the main trail to Black Lake, a spectacular lake in its own right.
(Trailhead is shuttle bus accessible.) A beautiful morning hike, this Lake is situated on top of Bierstadt Moraine giving brilliant views of Longs and the Front Range. As three routes converge on this lake, all of which lead to Shuttle Bus serviced trailheads, this hike can be done many different ways or even tacked onto a bigger venture. Arguably the best route is from the Bear Lake Trailhead to the shuttle parking lot as this stroll is mostly downhill. Walk down, take the bus back up.
This short hike leads to the top of a foothill near the edge of the park that gives a great view of the front range. A 3-mile hike, the trail is really close to the edge of the park which spoils some of the wilderness feeling you can get far inside the park, however the view from the top is more than worth it. The Lily Mountain Trailhead can be found a little ways south of Estes Park along Route 7.
