There are just as many, if not more fun summer activities all around Island Park.

Summer Activities


Fly fishermen come from all over the world to fish around Island Park for a reason: the rivers, creeks and lakes around us offer some of the best trout fishing an angler can have. Here are just a few options, but there are many more just waiting to be discovered!

Henry’s Fork of the Snake River & Harriman State Park
Henry’s Fork of the Snake River is known as one of the finest trout streams in the lower 48 states and offers some of the best dry fly fishing in the country. Grandma’s Cabin is just minutes from Henry’s Fork and Harriman State Park. Anglers can hire superior outfitting and guide services right in Last Chance. Guides are skilled in challenging the experienced angler or providing lessons to beginner fly-fishermen and women.

Few rivers can match the Henry’s Fork. It has a wide variety of water temperatures and insect hatches from stoneflies, mayflies, caddis and damselflies that provide a feast of bugs for the fish. Trout Unlimited has voted the Henry’s Fork the number one trout stream in the country.

The area tributaries of the Henry’s Fork provide unnumbered miles of streams and creeks providing scenery, solitude and excellent fishing for any angler. If you are looking for a guided fly fishing trip or just a great fly shop in the area, we recommend Henry’s Fork Anglers or the TroutHunter, which are both right here in Last Chance.

Don’t forget the Upper Henry’s Fork or “Box Canyon,” the Middle Henry’s Fork and the Madison River have fishing year-round. Come prepared to snowmobile or snowshoe in for possibly the best fly fishing experience of your life.

Henry’s Lake & Island Park Reservoir
Don’t miss Henry’s Lake, one of Idaho’s great high mountain lakes, which provides the kind of fishing (and size of fish) anglers dream about. Anglers fish for cutthroat, brook and cut-bow hybrid trout in what is considered one of the finest trout fisheries in the West. These fish are prized by Henry’s Lake anglers because of their superior fighting qualities.

You may also want to include Island Park Reservoir in your fishing to-do list, which is formed by the Island Park Dam. Recreation on this 11-square mile, 7,000-acre reservoir is administered by the Targhee National Forest. Fishing season is year-round for rainbow trout, cutthroat trout, coho salmon, yellow perch, and bluegill. Other recreational activities on the reservoir include boating, kayaking, canoeing and other water sports.

Our neighbors in Montana also offer world-class trout fishing with the Gallatin and Madison rivers within an hour of the cabin. Hebgen Lake also provides great fishing just over the border in Montana.

Fishing Yellowstone National Park
If fishing Yellowstone National Park is your dream, the Firehole and Gibbon Rivers are calling your name less than an hour away from the cabin. A special Yellowstone Fishing Permit is needed to fish in the park.
