When the water temperature drops in the Gulf of Mexico, hundreds of West-Indian manatees move to the warmer waters of Crystal River. The naturally-occurring warm water spring offers a constant 72°F water temperature in the bay, and a safe heaven to these endangered animals. If you are dreaming about encountering manatees in the wild, then head to Three Sisters Spring, at the heart of Crystal River. It is the only spot in Florida where people can legally swim and snorkel with manatees.

How to get to Crystal River for snorkeling?

Crystal River is a small city located in an inlet of the Gulf of Mexico, a 1.30 hour drive from Orlando and Tampa, and 4.30 hours from Miami. Due to environmental regulations, the easiest way to encounter the manatees is to book a tour in Crystal River. Many tour operators and diving centers in the town offer snorkeling tours, with prices ranging from $30 to 80 per person. Contact them in advance, because some snorkeling sites (including Three Sisters Springs) are sometimes closed, depending on tides, season and water temperature.

Crystal River snorkeling tips and recommendations

The area to explore covers the spring and its surroundings, where the depth is constant, around 5 to 12ft (1.5 to 4m). The crystal-clear waters offer spectacular underwater visibility, and the constant temperature of the springs (around 72 to 74°F) allows you to practice snorkeling all-year-round in good conditions.

Snorkeling with manatees at Crystal River

The areas around the springs are critical for protection of the West Indian manatee, and have been designated as manatee sanctuaries. One-sixth of Florida’s manatee population can be found in winter in Crystal River area. Because of this, more than 200 to 300 manatees can be present at the same time in Three Sisters Springs. They congregate in the warmest areas, especially in the winter months, from November to March.

Underwater landscape at Crystal River, Florida

Encountering manatees underwater is a profound experience you will always remember, but keep in mind that these gentle and giant animals are in the warm springs for survival. In winter, outside the springs, manatees experience cold stress and hypothermia. To allow the manatees to enjoy a peaceful rest in the springs, do not harass or disturb them. It is prohibited to touch, chase, or try to feed them.
