What Makes Saint Anthony Sand Dunes Worth Seeing
OHV country — Miles of sand to ride
Why Go
A local landmark people drive across the state to ride
The Saint Anthony Sand Dunes aren’t a side note on a map — they’re a destination recreation area with real scale. Warm-season OHVs carve lines across open sand. Families treat summer dune days like a beach without an ocean. Winter flips the surface into sledding and snowmobile country. Locals talk about “the dunes” the way other towns talk about their lake.
You get a playground that changes with the season: engines and open sand in summer, quieter town-and-swimming pairings, then cold-weather sledding when the snow sticks.
The Destination
What the dunes deliver season by season
Managed by the BLM, the dune field is big enough to feel like its own landscape — not a sandbox behind a subdivision. Rules, fees, and access points matter; the payoff is space to ride and roam.
Spring through fall is classic OHV and open-sand season. Groups come for the thrill and the photos. Smart planners check current BLM access before promising a dune day to thirty relatives.
Saint Anthony’s town feel pairs with the dunes: swimming areas, a quieter main-street pace, and supply runs that don’t require resort prices. The dunes are the adrenaline; town is the soft landing.
Winter is underrated. Sledding and snowmobiling on the dunes become the local cold-weather activity — different from Island Park trail systems, closer to town, and still genuinely fun for mixed ages.

OHV days and open sand. Confirm fees, vehicle rules, and access before you publish a guest itinerary.

Cooler sand, often fewer crowds, and great reunion-weekend energy when you want outdoor play without peak heat.
Winter
Sledding and snowmobiling take over. Pair with bigger Island Park trail days when the crew wants mileage.

Trip Notes
Practical details before you go
- Confirm current BLM road and dune access before you promise the group a dunes day.
- Sand + kids = laundry and water — plan for both.
- Assign one dunes day captain for vehicles, fuel, and rules so the host isn’t fielding twenty texts from the sand.
- Stock food and water in town; don’t depend on dune-side services for a group of 30+.
