Having a good time ranges from fishing and hunting, to horseback riding in the mountains, boating on the lakes and rivers, gentle float trips down the Henry's Fork of the Snake River, snowmobiling, cross country skiing, or just relaxing among the tall pines and quaking aspen. Mountain trails wind through aspen and pine groves, wild flowers, and sagebrush from 6,800 feet altitude at the highway to heights from 8,000 to 10,500 feet. These trails can be accessed with ATV's in the summer and snowmobiles in the winter. Over 500 miles of groomed snowmobile trails beckon the fun at heart.
Fishing is a major attraction to the area.
There are basic reasons why it is tops in trout fishing. It is high watershed country. Its streams and lakes having their inception in, and draining from, the Bitter Root Divide. They produce almost unlimited fish food. They tumble and meander through meadow, timberlands, and rocky gorges full of natural fish cover.
