Florida spring

Double Keyhole Spring

A dramatic coastal spring/cave system located near Hudson in Pasco County, Florida, behind the Sunwest Mine area and flowing into Fillmans Bayou. The site features twin vents in a shallow basin adjacent to marsh terrain, with the larger vent and cave entrance accessible only by boat. Strong groundwater discharge is evident and the cave passages reportedly extend hundreds of feet and hundreds of feet deep—qualified as technical or cave‐diving terrain.
