Manatee season in Crystal River

Crystal River is the only place in the United States where it is legal to swim with wild manatees. From mid-November through March, several hundred manatees move into Kings Bay and the spring-fed canals to escape the cooler Gulf water. Three Sisters Springs is the heart of the refuge. The canal behind the house is a daily pass-through.

Peak season is December through February. Cold fronts push manatee counts higher. The best snorkel mornings are the first warm sunrise after a cold snap.

When the manatees show up

Florida manatees migrate when the Gulf drops below about 68°F. The springs in Kings Bay hold a steady 72°F year-round, which is why they cluster here. Most years you will see early arrivals in mid-November and a peak count between Christmas and Valentine's Day.

Where to actually swim with them

Three Sisters Springs is the most famous spot but you cannot enter the spring run when manatees are present. You snorkel from the buffer zone or watch from the boardwalk. The legal swim is anywhere in Kings Bay outside marked sanctuary areas.

Most guests book a sunrise guided tour. Tours launch from Pete's Pier, Plantation, or one of the downtown outfitters and run 2 to 3 hours with wetsuits and snorkel gear included. You move slowly, stay horizontal, and let the manatees come to you. Touching is permitted only with one open hand if the manatee initiates contact.

What to bring

Most tour operators include the wetsuit, mask, snorkel, and a noodle for floating. Bring a swimsuit, a quick-dry towel, a warm change of clothes for after, water shoes if you have them, and your phone in a waterproof case. The water is 72°F. The air at 6 a.m. in January is colder than the water. Plan a hot shower at the house when you're back.

Rules that matter

Manatees are federally protected. Passive observation only. Do not chase, ride, dive down, separate a mother and calf, feed, or give water. Tour guides will repeat this and the rangers do enforce it. Following the rules also produces the best encounters. A still snorkeler is what a curious manatee approaches.
