Sand Hollow Sandpit Campground sits on the east side of the reservoir, on the Sand Mountain side, in the part of the park where the dunes start and the OHV trails leave from. The loop is more open than Westside — fewer trees, more sight lines, and a layout designed for trailer rigs hauling side-by-sides and quads. From most sites, you can hear engines on the dunes during daylight hours and the reservoir lapping at the shoreline a quarter mile west.
The OHV Loop
Sandpit is the campground for the people who came to ride. Sand Mountain — the dune complex that wraps the east side of the reservoir — is one of the highest-trafficked OHV destinations in the country, and the Sandpit loop is the staging campground. Most sites accommodate a long trailer, the loop roads are wider for pull-throughs, and the dump station is at the loop entrance. If you're hauling a side-by-side or quad, this is the loop you book.
Reservation Pattern
Same four-month window as the rest of the park, same reserveutah.com system. Sandpit fills slightly behind Westside for non-OHV traffic but ahead of Westside on weekends with major OHV events (the spring jamborees, fall meetups). Holiday weekends — Memorial Day, Fourth of July, Labor Day — clear within minutes. October and November weekends are the local sweet spot: cooling off, dunes still rideable, fewer crowds.
What the Loop Doesn't Have
Sandpit doesn't have the same shower infrastructure as Westside. The vault toilets are the on-site bathroom option; if you want a real hot shower, you walk or drive over to the Westside loop where the bathhouses live (state-park entry covers cross-loop access). The trade-off is real, and the reason most non-OHV campers default to Westside.
What Sandpit does have: direct access to the dunes without trailering across the park, more space per site for the trailer-and-toy-hauler combinations the park designed it for, and a generally more relaxed enforcement of generator hours since the loop is built for the OHV crowd. Quiet hours are still posted; the difference is in the social norm of the loop.
Riding from the Site
From the Sandpit loop, the OHV staging area is a short ride. Sand Mountain proper has hundreds of marked routes ranging from beginner-friendly bowls to expert-only steep faces. Utah State Parks issues OHV use tickets for unregistered visitors; bring registration or be prepared to register at the gate. Helmets are required; under-18 riders need a state OHV education certificate.
For supplies, Hurricane is five minutes south on the highway. Most Hurricane gas stations run OHV-friendly hours and sell fuel by the can. Several local outfits rent side-by-sides by the day if your trailer didn't make the trip.
If Sandpit is booked, Westside is the closer in-park option (no direct dune access from the site), and the Sand Hollow Resort RV Park outside the gate is the private full-service alternative. BLM dispersed camping on the south side of the reservoir provides a free fallback with no amenities and 14-day stay rules.
