About this spot
The Blue Hole of Santa Rosa is a famous bell-shaped artesian spring on old Route 66 — a clear pool about 80 feet deep, kept near 62F year-round, popular for swimming, scuba training, and jumps from the rock rim. It gets busy on summer weekends.
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.
