When families dream of visiting Yellowstone National Park, they’re often focused on geysers, bison, and those famous bubbling mud pots. But just outside the park’s west entrance, there’s a quieter, less-crowded corner of adventure that’s perfect for families: Island Park, Idaho.
Surrounded by pine forests, shimmering lakes, and a massive volcanic caldera, Island Park is more than just a stopover—it’s a playground for kids, a haven for parents, and a destination packed with memorable moments. Whether you’re glamping with us at Starlight Retreat or exploring the Yellowstone area, here are eight of our favorite things to do and see in and around Island Park.
1. Feel the Power of Upper Mesa Falls
If your family is chasing that “whoa” moment, Upper Mesa Falls delivers. This spectacular 10-story waterfall roars over a cliff of ancient lava rock, surrounded by lush forest and misty air that feels straight out of a storybook. The short boardwalk to the viewing platform is stroller-friendly and ideal for little legs, and the Mesa Falls Scenic Byway leading there is half the fun—especially if you’re spotting wildlife along the way.
Parents love the easy access and dramatic views, and kids can’t help but be mesmerized by the thundering water. Don’t forget to swing by the Lower Mesa Falls overlook on your way back—it’s a peaceful counterpoint to the excitement of the upper falls.
2. Explore Big Springs and the Johnny Sack Cabin
Tucked at the headwaters of the Henry’s Fork of the Snake River, Big Springs is one of those places where you can see nature at work. The water here is so crystal clear, it almost doesn’t look real—and the giant trout swimming just below the surface only add to the magic. Bring quarters to feed the fish and watch them swarm like shadows in the sun.
A short, easy trail leads to the historic Johnny Sack Cabin, a handcrafted log home built in the 1930s by a German carpenter barely over five feet tall. Kids are fascinated by the dollhouse-like charm, and parents will appreciate the peaceful beauty of this hidden Island Park gem.
3. Adventure and History at Harriman State Park
If there’s one place in Island Park where families can truly do it all, it’s Harriman State Park. Set on 11,000 acres of preserved land, this park offers kid-friendly hiking and biking, horseback riding, birdwatching, and even fly-fishing opportunities. Trails are gentle and scenic—ideal for first-time hikers or families with young kids in tow.
The park also features historic ranch buildings that give a glimpse into life in the early 1900s, adding a touch of education to your outing. Wildlife is abundant here—elk, moose, sandhill cranes, and more—so don’t forget your binoculars. Whether you visit in summer or return in winter for cross-country skiing, Harriman is always worth the trip.
4. Laugh Together at Mack’s Inn Playhouse
Sometimes, the best memories are made when everyone’s laughing. That’s exactly what you’ll get at Mack’s Inn Playhouse—a unique dinner theater known for its musical parodies and family-friendly fun. The performers double as your waitstaff, which adds to the playful, welcoming atmosphere.
After a few days of hiking and outdoor adventures, this lighthearted evening is the perfect way to unwind. The shows are silly enough to keep kids giggling and clever enough to keep parents entertained too. Plus, the home-cooked meals hit the spot after a day in the wild.
5. Climb to the Clouds on Sawtell Peak
Looking for panoramic views without a long trek? The Sawtell Peak Scenic Drive is your answer. Open during the summer months, this narrow but well-maintained road climbs over 9,800 feet, revealing sweeping views of Island Park, the caldera, and sometimes even Yellowstone itself.
The winding drive to the top is an adventure in its own right. Pack a picnic, stop along the way for photos, and let the kids marvel at the size of the trees and the height of the mountains. At the summit, the 360° view is breathtaking, and on clear days, you might even spot Henry’s Lake and the far-off Teton Range.
6. Float Down the Henry’s Fork
One of the best ways to soak in the Island Park scenery is from the water. Outfitters like High Mountain Adventures offer raft and kayak rentals perfect for a mellow float down the Henry’s Fork of the Snake River. The current is gentle, the views are unbeatable, and the occasional splash adds just enough thrill for young adventurers.
Along the way, you’ll pass pine-covered banks, peaceful meadows, and maybe even a moose cooling off in the water. Bring snacks and sunscreen, and plan for a few hours of unplugged, relaxed family time surrounded by nature.
7. Unplug by the Water at Island Park Reservoir
Sometimes, all you need is a lakeside afternoon. The Island Park Reservoir is a go-to spot for fishing, kayaking, or picnicking—and it’s easy to access from most Island Park cabins or vacation rentals. The water is calm and safe for swimming, with plenty of space for kids to run around, explore, and just be kids.
Whether you’re teaching your child to cast a fishing line or watching them skip stones until sunset, this is the kind of laid-back day that family trips are made for.
Discover More Than Yellowstone
There’s a reason more and more families are choosing to stay in Island Park as their home base for visiting America’s first national park—because the park and the surrounding area offer so much more than most expect.
From waterfalls to dinner theater, horseback rides to scenic drives, Island Park offers a world of adventure right outside your tent flap. And when you stay at Starlight Retreat, you’re never far from the next memory-in-the-making—whether it’s a s’mores-filled campfire, a trout sighting, or a giggle-fit from the back seat on the road to Sawtell Peak.
