Decontamination is available at the port of entry south of St. George on I-15 or at nearby Sand Hollow State Park. Please check the hours for decontamination.
Waterfalls: The waterfalls at Gunlock State Park are NOT FLOWING. Waterfalls happens when the snowpack is expended and no longer sustaining higher than normal flows in the Santa Clara River. Due to high amounts of runoff this season, debris may accumulate near the top of the falls. You can still view what is left of the falls from a safe distance.
Be Cautious and Observant: Recreating on the rocks near the waterfalls is dangerous. Rocks are slick, water is swift and covered hazards exist in the pools. We strongly encourage visitors to use caution and be observant in the area.
Fireworks: No fireworks, including sparklers, firecrackers and fireworks. NO FIREWORKS!!!
