Island Park, Idaho Travel Guide – A Scenic Gateway to Yellowstone
Tucked away in the heart of eastern Idaho, Island Park is a high-country paradise for outdoor enthusiasts, anglers, and nature lovers. Known for its stunning landscapes, endless recreational opportunities, and proximity to Yellowstone National Park, Island Park has become a year-round destination for those who want to immerse themselves in the rugged beauty of the American West without the heavy tourist crowds.
Whether you’re here for fishing, snowmobiling, hiking, or simply relaxing in a cabin by the river, Island Park offers an unforgettable mix of adventure and tranquility.
First Impressions – Wide Open Beauty
Island Park is famous for having the longest “Main Street” in America—a 33-mile stretch of U.S. Highway 20 lined with cabins, lodges, and scenic pullouts. At first glance, it feels like a small town stretched across a massive landscape of meadows, forests, and lakes. The pace is slower here, and the air feels cleaner and crisper, thanks to its elevation of around 6,000 feet.
Unlike crowded resort towns, Island Park has an unpretentious, laid-back vibe. You’ll find a mix of locals, seasonal residents, and visitors who come to escape city life.
Outdoor Activities – A Year-Round Playground
The real draw of Island Park is the incredible range of outdoor recreation. No matter the season, there’s something to do here.
Fishing and Fly Fishing
Island Park is a world-class destination for anglers. The Henry’s Fork of the Snake River is legendary in fly-fishing circles, offering crystal-clear waters and healthy populations of rainbow and brown trout. Nearby Henry’s Lake and Island Park Reservoir also provide excellent fishing for cutthroat and brook trout.
Whether you’re a seasoned fly fisher or a casual angler, the sheer variety of waterways here is unmatched.
Hiking and Wildlife Viewing
In summer and fall, the surrounding mountains and meadows come alive with wildflowers and wildlife. Popular trails include the Harriman State Park trails, where you can spot moose, elk, sandhill cranes, and even the occasional black bear. For more rugged terrain, the Targhee National Forest offers miles of backcountry hiking.
Island Park’s location also makes it an ideal base for day trips into Yellowstone National Park, just 20 minutes away.
Boating and Paddle Sports
The calm waters of Island Park Reservoir are perfect for kayaking, paddleboarding, or taking a pontoon boat out for a relaxing day. In warmer months, you can also float down stretches of the Henry’s Fork on a tube or raft.
Winter Sports
When the snow falls, Island Park transforms into a snowmobiler’s paradise. With over 500 miles of groomed trails and deep powder in the backcountry, it’s one of the top snowmobiling destinations in the West. Cross-country skiing and snowshoeing are also popular, with plenty of scenic trails available.
Lodging – Rustic to Refined
Island Park offers a wide variety of accommodations, ranging from rustic cabins to luxury lodges.
Cabin Rentals: Many visitors opt for private cabin rentals with river or lake views. These often come with full kitchens, hot tubs, and fireplaces—perfect for cozy evenings after a day outdoors.
Lodges and Resorts: The area has several well-equipped lodges like Sawtelle Mountain Resort and Lakeside Lodge, offering comfortable rooms and easy access to recreation.
Camping: For a closer connection to nature, there are numerous campgrounds and RV parks, including options within Harriman State Park and along the Henry’s Fork.
Dining – Local Flavor
While Island Park isn’t a foodie capital, it does have a handful of charming local spots worth visiting.
Connie’s Restaurant: A local favorite for hearty breakfasts and homestyle dinners.
TroutHunter Lodge & Restaurant: Combines a fly shop, lodge, and dining room, with excellent views of the Henry’s Fork.
Cafe Sabor: A casual spot offering surprisingly good Mexican food with outdoor seating in the summer.
Given the remote location, it’s worth stocking up on groceries in nearby Rexburg or Idaho Falls if you plan to cook at your cabin.
Proximity to Yellowstone
One of Island Park’s biggest advantages is its proximity to Yellowstone National Park. The West Entrance in West Yellowstone, Montana, is just a 20-minute drive from most parts of Island Park. This makes it easy to explore Yellowstone’s iconic attractions—like Old Faithful, Grand Prismatic Spring, and the Lamar Valley—without staying inside the park’s often-booked lodges.
This location is especially appealing in peak summer months when staying inside Yellowstone can be both expensive and crowded.
Unique Attractions in Island Park
While Yellowstone is the star attraction nearby, Island Park has its own unique spots worth exploring.
Big Springs: A crystal-clear natural spring that produces over 120 million gallons of water each day. You can see large trout right from the bridge.
Mesa Falls Scenic Byway: A short, beautiful drive leading to Upper and Lower Mesa Falls, two of Idaho’s most impressive waterfalls.
Johnny Sack Cabin: A historic log cabin with intricate woodwork, located near Big Springs.
Harriman State Park: A 16,000-acre wildlife refuge with hiking, biking, and skiing trails.
Best Times to Visit
Summer (June–August): Warm days, cool nights, and prime fishing, hiking, and boating weather. This is also peak tourist season.
Fall (September–October): Fewer crowds, brilliant fall colors, and excellent wildlife viewing.
Winter (December–March): Snowmobiling, cross-country skiing, and cozy cabin stays.
Spring (April–May): Quieter months with opportunities for early fishing, but some trails may still have snow.
Tips for Visiting Island Park
Book Lodging Early in Summer: While it’s less crowded than Yellowstone, cabins and lodges still fill up quickly.
Bring Layers: Even in July, evenings can be chilly at 6,000 feet.
