About Blue Hole of Santa Rosa
A near-perfect circle of startling blue water opens in the middle of Santa Rosa. The spring-fed Blue Hole drops far deeper than its modest surface suggests, making it a favorite for scuba divers as well as swimmers and curious roadside visitors.
Its clear water and abrupt depth make the place feel like a portal cut into the plain. Stay within posted swimming areas and check current rules before diving, since scuba access has separate requirements. Even from the edge, the color is worth the stop.
