King Spring is a boat-access freshwater spring in Crystal River.
King Spring is a boat-access freshwater spring on the south side of Banana Island in Crystal River. The site combines a shallow basin with a deeper cavern reach, so it works best for divers who want calm spring water, clear structure, and a route that still needs buoyancy control. Seasonal manatee rules and refuge boundaries shape the plan, and winter access is more constrained than summer diving.

Depth range, seasonality, and planning context.
Reported Depth
4.6m - 19.8m
Depth Note
Shallow water over the vent is about 15 ft, with a deeper cavern section around 50 ft and an overall spring depth near 65 ft.
Best Season
May through September is the easiest window; winter is mainly for guided manatee viewing under refuge rules.
Typical Conditions
Shallow spring basin, a deeper cavern option, and visibility that is usually decent but can drop when bay water moves in.
Hazards, restrictions, and access requirements.
Key Hazards
Safety Notes
Keep clear of sanctuary buoys, avoid stirring bottom sediment, and only enter the cavern if your training and gas plan fit overhead water.
Access Restrictions
Boat access only. From November 15 to March 31, manatee-sanctuary boundaries restrict diving to the marked keyhole or areas outside the sanctuary.
Legal Notes
Crystal River National Wildlife Refuge rules apply, including seasonal sanctuary boundaries and any in-water guide requirements during manatee season.
Community notes to help plan your visit.
Scuba Diving
Scuba is the primary way to experience King Spring. The basin is beginner-friendly, but the cavern route and seasonal sanctuary rules make a guided plan the safer fit.
Freediving
Freedivers can use the shallow spring area when conditions and rules allow, but the site is better known for guided scuba and manatee-viewing access.
Snorkeling
Snorkeling is a core activity here, especially in manatee season, but entry zones and sanctuary boundaries still matter.
