Manatee-safe spring snorkeling, shallow scuba and summer scallops on Florida's Nature Coast
Overview
Crystal River and Homosassa combine warm aquifer springs, a protected winter manatee refuge, shallow local scuba training and seasonal Gulf scallop snorkeling. The signature wildlife experience is passive snorkeling at the surface in Kings Bay, not scuba with manatees. From November 15 to March 31, seven federal manatee sanctuaries close to entry, and Three Sisters may be temporarily closed to swimming during cold-weather aggregations. King Spring has a marked winter scuba keyhole; Three Sisters scuba is allowed only April 1 to November 14. July 1 to September 24 was the 2026 Citrus County scallop harvest window. Non-divers can use boardwalks, a wildlife park, marsh trails and archaeological sites. Plan locally by car and permitted day operators, not liveaboard.
Winter manatee observation is possible only through passive surface snorkeling or land viewing; protected sanctuaries stay off-limits.
Kings Bay spring water remains near 22°C, but Three Sisters and King Spring each have specific seasonal scuba and vessel rules.
Homosassa and Crystal River are documented launch bases for regulated July-September bay scallop snorkeling.
