St. Anthony Sand Dunes: A Surprising Day Trip Idea for Your Island Park Vacation Rental Cabin Guests
When most travelers think about a vacation in Island Park, Idaho, they picture pine forests, alpine lakes, and the geysers of Yellowstone just up the road. So it surprises just about everyone the first time they see the St. Anthony Sand Dunes — 11,000 acres of rolling, snow-white sand sitting in the middle of an otherwise green agricultural valley, less than an hour from your Island Park vacation rental cabin. For cabin owners looking to give guests a one-of-a-kind day trip recommendation, the dunes are a hidden gem that adds variety to any Eastern Idaho itinerary.
Where Are the St. Anthony Sand Dunes?
The St. Anthony Sand Dunes are located just outside the small town of St. Anthony, Idaho, roughly 45 minutes south of Island Park along Highway 20. The drive is straightforward — a scenic descent out of the Henry's Fork country into the Snake River Plain. Guests at your Island Park cabin can leave after a relaxed breakfast and be standing on a 400-foot dune by mid-morning. The most popular access point is Egin Lakes, where you'll find a paved entrance, restrooms, day-use parking, and a small lake at the base of the dunes that's perfect for cooling off after a hike.
Why Your Cabin Guests Will Love the Dunes
The sand dunes are visually striking — bright white quartz sand stretching for 35 miles, shifting in the breeze, framed by the Tetons and Centennial Mountains in the distance. Photographers love the contrast against blue summer skies. Families love how kids can run, slide, and roll with zero risk of getting muddy. And anyone who has spent the morning on a forest trail or fly fishing the Henry's Fork will appreciate the entirely different landscape just down the road. It's the kind of place guests post about, tag your rental in, and remember long after they head home.
What to Do at the Sand Dunes
The dunes offer something for every kind of traveler. Active guests bring sandboards, sleds, or even cardboard scraps and slide down the bigger faces. Off-roaders bring ATVs and side-by-sides and explore designated riding zones — a natural follow-up activity if you've already been promoting your cabin to the OHV crowd. Quieter guests can hike to the top of "Choke Cherry Hill," picnic along the shoreline of Egin Lake, or simply watch the sunset turn the sand pink and gold. Dogs on leash are welcome in most areas, which is a nice perk to mention if your cabin is pet-friendly.
When to Visit and What to Bring
The dunes are open year-round, but late May through September is the sweet spot. Early summer keeps the sand cool enough to walk on barefoot, while August afternoons can get genuinely hot — recommend morning or evening visits during peak summer. Guests should bring plenty of water, sunscreen, sunglasses, and sturdy shoes for the hike up. Sandals work for short visits but sink fast on steep slopes. There's no shade out on the open dunes, so a lightweight pop-up canopy or beach umbrella is a thoughtful addition to your cabin's gear closet — guests will love finding it ready to grab.
How to Recommend the Dunes in Your Guest Welcome Materials
The St. Anthony Sand Dunes consistently surprise first-time visitors, which makes them a perfect "insider tip" to feature in your cabin's welcome book or digital guidebook. Include a one-paragraph description, the drive time from your cabin, the Egin Lakes parking address, and a couple of nearby food stops — Big Jud's in Ashton or any of the casual diners in St. Anthony itself work well. Add a few practical reminders: bring water, watch for blowing sand on windy days, and check the weather before heading out. Guests who feel well-prepared leave better reviews, and unique recommendations like this one help your listing stand out from cookie-cutter cabin write-ups.
Combine the Dunes with Other Eastern Idaho Stops
Because the drive between the dunes and your Island Park cabin passes through Ashton, guests can easily turn the trip into a loop. A morning at the dunes pairs nicely with an afternoon at Mesa Falls or a stop at one of the Henry's Fork river accesses. Owners promoting longer stays can suggest the dunes as the second or third day of a guest's itinerary — a change of pace from forest hikes and Yellowstone day trips that keeps multi-day visits feeling fresh.
