Twin Caves Spring
Magnitude 3Merritt’s Mill PondMariannaPublic
Photo by: Florida SpringsA popular cave-diving sinkhole. Access is publicly accessible via paddle from the river or within the millpond. The spring system includes multiple submerged cave tunnels reaching depths of ~30 m, and is known for often low visibility or zero‑visibility conditions due to heavy silting in the cave passages. While water at the pond surface can be moderately clear, interior cave clarity is variable and potentially hazardous. For the best chance of clarity, look for water heights below 76.8 feet.
