Safety · Destination Guide
Manatee-safe spring snorkeling, shallow scuba and summer scallops on Florida's Nature Coast
This is a federally managed manatee refuge with visitor water-access constraints, not a theme-park swim. Check current USFWS sanctuary markings and closures first. Use a local qualified instructor/guide for scuba and any freediving, keep boats out of no-entry habitat, and monitor NWS, NHC and FWC conditions. For serious injury call 911 first; follow with DAN for dive-specific medical advice. Never advertise a wildlife meeting or a particular spring as guaranteed open.
Separate three activities: (1) passive Kings Bay surface snorkeling with manatees, (2) lawful spring scuba inside specifically open water, and (3) Gulf scalloping under FWC fishing rules. In Kings Bay, do not dive down on manatees, harass animals or enter sanctuaries. King Spring scuba is within the buoy-marked winter keyhole/otherwise legal water, and Three Sisters scuba is restricted to April 1-November 14. Spring vents, moving boats, unpredictable silt and local restrictions demand a briefing. All formal apnea training requires an attentive qualified buddy, recovery procedure and appropriate site. No overhead penetration. Summer heat, lightning and Gulf storms can change operations rapidly.
In a medical emergency in Crystal River/Homosassa, call 911 and give a precise dock/launch location. TGH Crystal River hospital at 6201 N Suncoast Blvd lists an emergency department; TGH North also lists a 24/7 Citrus Hills emergency center. For suspected dive injury supply oxygen if trained and available, avoid further dives, and call Divers Alert Network at +1-919-684-9111 after activating EMS. Do not assume a specific local hyperbaric chamber is ready for emergency recompression; destination, transfer and stabilization require EMS/DAN direction. Keep emergency contacts and mobile coverage backups for boats.
Protected manatee sanctuaries
USFWS no-entry boundaries apply November 15-March 31 and can be reinforced by temporary cold-weather Three Sisters in-water closures. Never enter closed water, regardless of a tour or rental.
Do not convert a snorkel encounter into a dive
Use passive viewing from the surface and follow FWC’s look-don’t-touch guidance. USFWS prohibits harassment, including chasing, feeding, surrounding or diving down on resting or feeding manatees. Leave every animal room to move and do not initiate contact; scuba bubbles may disturb them.
Boat traffic, navigational channels and low visibility
Kings Bay, Homosassa channels and Gulf flats carry boats and variable tidal/current/sediment conditions. Use surface visibility measures, guided routes and a buddy; do not assume spring clarity eliminates collision risk.
Summer lightning and Gulf storm risk
NWS reports frequent thunder in late May-early October; NOAA Atlantic hurricane season runs June 1-November 30. Captains may cancel; do not enter water during lightning or ignore storm and marine warnings.
Follow USFWS no-harassment rules and FWC look-don’t-touch guidance. Do not chase, feed, touch or disrupt manatees; keep their routes to warm-water refuges unobstructed. Winter sanctuaries protect essential survival habitat. Keep fins away from sediments and seagrass, obey slow-speed zones, do not anchor on seagrass or dump scallop shells in inland channels, and support habitat restoration efforts. FWC advises reporting injured manatees to 1-888-404-3922. A spring's visibly clear water is not a guarantee of water quality or unrestricted access.
Do Not Do This
Avoid entering when protected manatee sanctuaries. Confirm local briefings before committing.
