About this spot
Porcupine Reservoir sits in Cache Valley near Paradise, Utah, held back by the 165-foot Porcupine Dam. The popular jumping cliffs rise from 8 to roughly 60 feet at the reservoir's southeast corner, but there's no shoreline trail to them, most visitors swim across open water to reach the base, and the crossing is longer and colder than it looks, so bring a flotation aid. Check water depth and submerged debris before jumping since levels shift with reservoir management. The reservoir is popular for fishing, boating, and swimming, but it's day-use only with no lifeguards, no overnight camping, and no developed facilities. Free public access; no permit required.
Safety first. Cliff jumping is inherently dangerous and can cause serious injury or death. Conditions — water depth, submerged hazards, and access — change constantly. CliffScout is community-sourced reference information, not a guarantee a spot is safe. Always assess the conditions yourself before jumping, and never jump where you're unsure. You assume all risk.
