Sand Hollow State Park sits about 15 minutes east of St. George in Washington County, Utah. It covers roughly 20,000 acres of red desert terrain anchored by a 1,322-acre reservoir. The water stays warm enough for swimming from late spring through early fall. For RV travelers using the St. George area as a base camp, it is one of the best day trip options within easy driving distance. Open water, sand dunes, and desert trails put more variety into a single park than most destinations in Southern Utah offer on their own.
The problem most visitors run into is showing up without a plan. Sand Hollow is not a small park. It spans multiple recreation areas with different access points and different fee structures. If you just drive in and wing it, you end up circling parking lots wondering where to start.
This guide covers what Sand Hollow State Park offers for RV visitors. It walks through the activities, the camping setup, and how to build a Sand Hollow day into a broader St. George area trip.
Why Sand Hollow State Park Draws RV Travelers to Southern Utah
Most people discover Sand Hollow because of the reservoir. The water is the centerpiece and the main draw, especially from May through September when surface temperatures climb into the 70s and 80s. But the park is much more than a lake. The surrounding terrain includes open sand dunes for OHV riding, slickrock trails for hiking, and enough shoreline to spread out even on a busy weekend.
What makes it especially appealing for RV travelers is the proximity to everything else in the region. You can spend a morning on the water at Sand Hollow, then drive 15 minutes back to your RV park in St. George or Washington. Shower up and head to Snow Canyon or a restaurant in town that same afternoon. That kind of flexibility is hard to find at more remote destinations where a single park visit eats the entire day.
The landscape itself is striking. Red sandstone cliffs frame the turquoise water, and the contrast is unlike anything you will see at a typical lake. Photographers and families both gravitate here because the scenery delivers without requiring a strenuous hike or a long shuttle ride to reach.
Activities at Sand Hollow State Park for Every Type of Visitor
Boating is the headline activity and the reason most people make the trip. The reservoir allows powerboats, jet skis, kayaks, and paddleboards. A boat ramp and marina provide launch access, and several rental operators work out of the area if you do not have your own watercraft. Weekends in summer get crowded at the ramp, so an early arrival makes a noticeable difference.
Swimming is the second draw. Sand Hollow has a designated swim beach with sandy shoreline and gradual entry into the water. It is one of the few places in Southern Utah where you can swim in open water without a long drive. Families with young kids find the beach area manageable because visibility is good and the drop-off is gentle.
The sand dunes on the south side of the park attract OHV riders from across the region. If you travel with ATVs or side-by-sides, this is one of the more accessible riding areas in Utah. Permits are required, and the dune area operates under separate rules from the reservoir side, so check current regulations before unloading.
Hiking options are more limited but worth mentioning. The slickrock trails around the reservoir offer moderate terrain with good views of the water and surrounding desert. These are not long-distance trails. Most loops run two to four miles and work well as a morning warm-up before heading to the water.
Sand Hollow State Park Camping and Facilities for RV Visitors
Sand Hollow has its own campground with sites that accommodate RVs. The main campground offers full-hookup sites with electric, water, and sewer connections. Several loops sit closer to the reservoir, while others are set back with more shade and privacy. Site sizes vary, so if you are running a larger rig, confirm dimensions when you reserve.
Reservations are handled through the Utah State Parks online system. Spring and fall weekends book up fast, often weeks in advance. Midweek availability is easier to find, even during peak season. If your travel dates are flexible, arriving on a Tuesday or Wednesday opens up significantly more options than a Friday.
Facilities at the park include restrooms, showers, and a small day-use area near the beach. The marina has a general store for basic supplies, but do not count on it for a full grocery run. Stock up in St. George before heading out. The park also has dump stations for RVs that are not on full-hookup sites.
Keep in mind that Sand Hollow campground works well for a one or two night stay. It is not a full-service resort. Sites are functional, not luxurious. If you want a pool, laundry, or wider site spacing, an RV park in the St. George area makes a better home base. Treat Sand Hollow as a day trip instead.
How to Pair Sand Hollow State Park With Your RV Base in St. George
The drive from most RV parks in St. George or Washington to Sand Hollow takes about 15 minutes. That makes it one of the easiest day trips in the region. You do not need to break camp, tow your rig, or commit to an overnight. Just load the truck, drive east, and you are there.
A solid day trip plan starts early. Arrive by 8 or 9 in the morning to claim a good parking spot near the beach or the boat ramp. Spend the morning on the water or at the swim beach. Break for lunch at your vehicle or at one of the covered picnic areas. Spend the afternoon on the dunes or the slickrock trails, then head back to your RV park before dinner.
If you are looking for things to do in St. George, Utah beyond Sand Hollow, the area delivers well. Snow Canyon State Park is 20 minutes north with some of the best hiking in the region. Red Cliffs National Conservation Area offers desert trail options. Downtown St. George has restaurants, shops, and a growing food scene that gives you a break from camp cooking.
The ability to hit multiple parks from a single base camp is what makes the St. George corridor work for RV travelers. You are not locked into one location. You have Sand Hollow for water days, Snow Canyon for hiking days, and Zion National Park less than an hour away for the bigger excursions.
Making Sand Hollow State Park Part of Your Southern Utah RV Trip
Sand Hollow deserves more than a quick stop on the way to somewhere else. The reservoir, the dunes, and the trails add up to a full day of recreation that stands on its own. For RV travelers based in the St. George area, it is one of the highest-value day trips available. The drive is short, the variety is real, and the scenery competes with anywhere in the state.
Plan your visit around the season and the day of the week. Spring and fall offer the best balance of warm weather and manageable crowds. Summer brings the warmest water but also the biggest crowds, especially on weekends. Midweek visits in any season give you the best experience with the least hassle.
Check campsite availability early if you want to stay overnight, and stock up on supplies in St. George before you head out. Whether you camp at the park or visit from your home base, Sand Hollow State Park earns a permanent spot on the Southern Utah itinerary.
