Located just 20 minutes from St. George in Washington County, Sand Hollow State Park is one of Southern Utah’s most dynamic outdoor destinations. Combining warm reservoir waters with towering red sand dunes and expansive desert terrain, Sand Hollow offers a rare blend of water recreation and off road adventure in a single location.
For visitors exploring Zion National Park and the surrounding area, Sand Hollow delivers a high energy contrast to canyon hiking, making it one of the best things to do in Southern Utah during spring, summer, and fall.
Why Sand Hollow State Park Is So Popular
Sand Hollow stands out because it offers two completely different landscapes in one park:
- Sand Hollow Reservoir, warm clear water ideal for swimming, boating, paddleboarding, and kayaking
- Sand Mountain OHV Area, expansive red sand dunes and technical desert trails for ATVs and UTVs
Few state parks in the Southwest provide this level of versatility.
It is common to see visitors boating in the morning and riding ATVs across dunes in the afternoon.
Sand Hollow Reservoir: Warm Water Recreation in the Desert
Unlike many alpine lakes in Utah, Sand Hollow Reservoir warms significantly during late spring and summer, making it especially attractive for swimming and water sports.
Popular Water Activities
- Swimming from sandy shoreline beaches
- Power boating and wake surfing
- Paddleboarding and kayaking
- Jet skiing
- Fishing, including largemouth bass and bluegill
The reservoir’s red rock backdrop creates a striking contrast against blue water, making it a favorite for photography and drone footage.

Sand Mountain: Southern Utah’s Sand Dune Playground
Adjacent to the reservoir lies Sand Mountain, a massive red sand dune system popular with off road enthusiasts.
This area features:

- Technical rock crawling
- Scenic desert overlooks
- Extensive ATV and UTV trail networks
The terrain accommodates both beginners and experienced riders.
