Overview
Tucked quietly away in the scenic red rock country of southwestern Utah, this state park centers around a beautiful, refreshing reservoir surrounded by rugged lava fields and orange sandstone hills. The park is most famous for its spectacular, seasonal cascading waterfalls that plunge over orange rock ledges when the reservoir overflows in spring, creating an ethereal and highly sought-after oasis for swimming and photography.
Practical Info
Every day7:00 AM – 7:00 PM
Suggested Duration1.5-2.5 hours
Best TimeAn unmissable but highly restrictive phenomenon occurs in spring (March to May) strictly during high snowmelt overflow years (Note: The world-famous red rock cascading waterfalls only appear when the reservoir spills over the red sandstone bluffs; check live park updates as it remains completely dry in regular seasons). Hit the ledges by 9:30 AM.
Getting ThereSituated northwest of St. George at 1450 Gunlock Road. Accessible strictly by car: from downtown St. George, follow Sunset Boulevard northwest, which transitions into Gunlock Road. Wind through the desert hills for 15 miles to the reservoir; a dedicated state park free paved surface parking lot sits positioned directly at the foot of the rock spillway cascades.
Travel Tips
- Highly Seasonal Overflow Waterfall: The park's famous waterfalls only flow when the Gunlock Reservoir exceeds capacity, typically during peak spring runoff (March–May). Check the live waterfall status on the official page before making the trip to avoid disappointment.
- Slippery Red Rocks & Cliff Jumping Ban: Sandstone surfaces around the falls harbor invisible slick algae and moss. Cliff diving or jumping into shallow unmonitored pools is strictly banned due to recurring severe spinal injuries.
- Early Morning Capacity Limits & Credit Card Only: During peak spring flow, lots are saturated by 9 AM, triggering 'one-in, one-out' traffic controls. The entrance stations are fully automated and cashless; ensure you have credit cards ready.
Reviews
Positive
- When the spillway waterfalls cascade down the red rock cliffs due to high reservoir levels, the contrast of orange stone and white foam is visually stunning.
- The reservoir surface is wide and calm, ideal for swimming, paddleboarding, and boating, with flat, clearly signed accessible viewing boardwalks.
- Public facilities are frequently maintained; the upgraded flushing restrooms are spotless, and the picnic pavilions are clean and organized.
- It charges a reasonable, transparent per-vehicle entry pass fee with no inflated tourist-trap pricing inside, offering exceptional outdoor value.
Heads up
- The iconic waterfalls are strictly seasonal; during the long dry season, it is just a dry slab of rock, turning into a photo trap for many visitors.
- Once the spring waterfalls flow, visitors flock in; because the park is small, crowd density instantly surges with intense lines and severe parking shortages.
- Outside the falls and reservoir dock, peripheral sandy hiking trails offer zero tree shade, making sunstroke a real risk under the baking summer sun.
- Public transit is unavailable, requiring driving; during peak flows, slippery overflow rock edges lack sufficient safety ropes or anti-slip warnings.
