Sand Hollow State Park

Utah’s most-visited state park, Sand Hollow, earns its popularity with a warm-water reservoir and access to miles of desert landscape prime for off-roading adventure.

Red sandstone cliffs rise from the beach, the reservoir glows emerald green against the red shore, and Sand Mountain’s dunes stretch south across the horizon. On any given summer day, you’ll see boats, paddleboards, jet skis, and ATVs all working the same park, without any of them crowding each other out.

What you’ll find onshore: roadrunners, quail, lizards, and the occasional snake sunning on the rocks. 

What you’ll find in the reservoir: largemouth bass, bluegill, crappie, and a Cessna 320 twin-engine airplane. 

When to Visit

Spring

Average highs climb through the 70s and 80s, the reservoir is holding peak water capacity for the season, and the occasional wildflowers bloom along the shoreline.

Summer

The reservoir truly shines, with highs near 100° and water temperatures between 81° and 86°. Mornings and evenings are an excellent time to spend on the dunes, while mid-day is free for floating. 

Fall

Weather settles back into the 70s and 80s with warm water temperatures holding into October: fewer boats, same inviting reservoir. Excellent conditions on Sand Mountain.

Winter

Mild days in the 50s and quiet trails. The dunes are rideable, the views are postcard-worthy, and you might get lucky enough to have the place to yourself.


Things to Do

Boating and Wakesports

The reservoir is one of the warmest in Utah and a favorite for wakeboarding, water skiing, and tubing. Launch from the marina on the west side, where you’ll find a boat ramp, dock, and plenty of parking for trailers.

Fishing

Cast from the shore or from a boat for largemouth bass, bluegill, and crappie. A Utah fishing license is required. The reservoir is certified free of invasive mussels, so plan for a boat decontamination stop on your way in.

Paddleboarding and Kayaking

The south and east coves stay calm most mornings. Rentals are available through park concessionaires, and early-morning paddles are as peaceful as it gets in Greater Zion.


Scuba Diving

Yes, really. Sand Hollow has an on-site dive shack and clear enough water for certification dives. Call ahead for lessons and rentals. You’ll be able to see the famous Cessna 320 twin-engine airplane and a VW bus, among other oddities. 

For boat launch hours, decontamination requirements, and rental information, visit Sand Hollow State Park.

Ride the Dunes

The terrain ranges from wide-open bowls for beginners to technical hill climbs that draw riders from across the country. Bring your own rig or rent from a local outfitter. Guided tours are available and highly recommended if it’s your first time on the dunes.

Sand Hollow is the only Utah state park with direct OHV access to Sand Mountain, a 15,000-acre stretch of dunes, ravines, and slickrock ridges just south of the reservoir. A tunnel beneath SR-7 connects the park to the riding area, so you can stage at your campsite and ride straight onto the sand.

Greater Zion offers a broad network of off-highway riding across the region. Explore more routes here.

Tee Off Next Door

Just outside the park entrance, Sand Hollow Resort is home to the award-winning Sand Hollow Golf Course.

Orange sand traps cut through green fairways against a backdrop of red cliffs and the reservoir beyond. Repeatedly included in GolfWeek’s Top 100 Resort Courses, it’s a bucket-list round for any serious golfer and a scenic one for anyone who likes walking a beautiful course. Sand Hollow Resort is equally as beautiful, offering a variety of rooms, suites, condominiums, and vacation homes.

Camp at the Water’s Edge

Sand Hollow has five campgrounds, each with its own personality:

  • Westside Campground has 50 full-hookup sites closest to the boat ramp and day-use beach. It’s the go-to for boaters.
  • Lakeview Campground offers a mix of full and partial hookups on the east shore. Newer, quieter, and spaced for privacy.
  • Sandpit Campground sits nearest the Sand Mountain tunnel, with a mix of partial hookups, dry sites, and large group sites that hold up to a dozen vehicles. This is OHV headquarters.
  • Beachside Campground has three walk-in sites and two reservable cottages — one pet-friendly, one ADA accessible. Cottages sleep up to six and book up to four months in advance.
  • Primitive Campground runs along the east and south shores for dispersed dry camping. No hookups, one vault toilet, and some of the best stargazing in the park.
Campsites book quickly in spring and fall — reserve well in advance through the state park website.

Plan to Stay Awhile

Sand Hollow anchors a day on the water, but the surrounding area fills out a full trip. Nearby Hurricane and La Verkin offer lodging and small-town charm. Zion National Park is a 35-mile drive east. And Greater Zion’s accommodations, restaurants, and additional state parks — Quail Creek, Snow Canyon, and Gunlock — are all within a short drive.

Babylon Arch

Tucked into the Red Cliffs National Conservation Area about 25 miles from Sand Hollow State Park, Babylon Arch rewards hikers with red rock formations, sandy washes, and a striking stand-alone arch about a mile down the trail. It’s a moderately challenging route.
