East Inlet
RMNP | Top Pick, Free
This is my favorite trail! It’s part of RMNP, but the East Inlet Trailhead is actually located on the eastern end of Grand Lake. (So you don’t even need a park pass.) If you hike to Lake Verna, it’s about 13 miles round trip with quite a bit of elevation gain. But fear not, however far you go on this trail, it’s worth it! Adams Falls is less than half a mile from parking lot and Lone Pine Lake is a nice lunch destination.
