Southern Utah Lakes & Reservoirs Guide

By Ethan Carter · Discover 435

When St. George hits 105°F, hiking is out of the question past 9 AM. Here is your practical breakdown of Sand Hollow, Quail Creek, and Gunlock for cooling off.

1. Sand Hollow State Park

The crown jewel of Southern Utah water recreation. Famous for its warm blue water, red sand beaches, and massive off-highway vehicle (OHV) sand mountain that literally drops right into the water.

2. Quail Creek State Park

Just a few miles north of Sand Hollow, Quail Creek is generally colder, deeper, and quieter. It is tucked into a valley, creating a windbreak and making it much calmer than Sand Hollow.

3. Gunlock State Park

Located west of St. George, Gunlock is smaller and more rugged. It's famous primarily for its seasonal waterfalls, which only flow during heavy snowmelt years (typically late spring).

Swimmer's Itch (Cercarial Dermatitis) Warning

A critical note for locals and visitors: Swimmer's Itch is a seasonal issue in both Sand Hollow and Quail Creek, typically peaking in early to mid-summer when the water warms up.

Park Passes and Fees

All three reservoirs are Utah State Parks. Day use fees are generally $20-$25 per vehicle depending on the park and residency status.

Highly Recommended: If you are a Utah resident planning to visit more than 4 times this year, buy the Utah State Parks Annual Pass ($125). It pays for itself rapidly and makes popping over to Quail Creek for a 2-hour evening paddleboard session feel free.
