The area is dominated by lodgepole pine and Douglas-fir forests, scattered stands of aspen trees and open meadows.
Island Park is home to grizzly and black bear, elk, deer, moose, antelope, eagle, trumpeter swans, pelicans and many song birds.
In fall, you may hunt, fish or hike. Fishing is fantastic, while hunters stalk wild game with bows, muzzle-loaders and rifles. Also, there is back country hiking and canoeing to enjoy.
If you love adventure, Island Park is the place to come in the winter. Experience all the outdoor attractions high mountain country has to offer. Island Park’s high elevation means that there is plenty of snow from mid-November to mid-March. There are 600 miles of groomed snowmobile trails and many acres of open meadows to play in. Cross-country skiing is great with groomed trails in the Targhee Forest and Harriman State Park. In less than half an hour, you can be on the Rendezvous Trail System in West Yellowstone, the training ground for world class skiers and biathletes. Downhill skiing at Grand Targhee or Big Sky is not far away and there is plenty of fun to be had snowmobiling, skiing or snow-coach riding.
The Island Park area has many area activities and attractions for the traveler such as the Johnny Sack Cabin, which is on the National Register of Historic Places located at Big Springs. The cabin has many unique features and is open to visitors during the summer. The Island Park Reservoir with five boat launch sites is popular for boating, fishing and water-skiing. The reservoir is situated above Box Canyon, which provides excellent fly-fishing opportunities and scenic float trips.
