This is a good nature trail, as many kinds of wildflowers, trees, and
birds are found. Deer are common in the area. Swimming is good in late
summer. This is also a favorite trail for overnight hikers as it leads
to the wilderness area of the eastern part of the park.
Hardy hikers may wish to go beyond Twin Lakes. The trail continues past
Rainbow Lake to Snag Lake, 3.5 miles, and another trail goes to Butte
Lake, 5.5 miles.
