Three Sisters Springs - Swim with Manatees in Florida

When Is the Best Time 

The West Indian Manatee migrates to Crystal River and the surrounding springs roughly mid-November and stays around the springs until mid-March. This is not guaranteed! In 2018 they already left the springs mid-February due to an unusual high day temperature. Guided tours are offered from November to end of March. You experience most activity during the early morning. If you like to get interactions with manatees book the early morning tour in advance.

The manatees come here during winter time because they get stressed by the cold gulf if the temp goes below 68°F / 20°C. Although they look like to be prepared for cold temperatures their body has not much fat for insulation. The springs have a constant temp of 74°F / 23°C. The reason that they gather around the springs.

During high tide, they move to the Three Sisters Springs, and at low tide, they gather outside in the channel at Idiot’s Delight I and II. Often 400 to 500 manatees can be seen at the springs.

Visiting Three Sisters Springs

If you like to see them in high numbers inside the spring, come during high tide. Tide times Crystal River

It is almost impossible to avoid crowds while swimming with the manatees. Even early morning expect 30 to 40 people in the water. The Three Sisters Springs, however, are tranquil when they open the gate at 8.30.


During the peak season of the manatees, it can be pretty chilly in the morning. On average it's roughly 50°F / 10°C cold in the early morning. We experienced 28°F / -2°C which happens rarely. It was pretty cold when we got out of the water. Day temps are usually between 58°F / 15°C and 70°F / 21°C. Precipitation occurs year-round with its peak in the summer months. It’s quite hot and muggy in the summer and temps are around 90°F / 32°C.

Top Tip

We highly recommend staying here for a couple of days. Visit the Three Sisters Spring, have a look to one of the many other springs like the Rainbow Springs for swimming, enjoy the manatee encounter. Actually, we planned camping in the Rainbow Springs State Park. Due to the cold night temps of 32°F, we’d booked a room at the Hampton Inn Crystal River last minute. It was just a 5 minutes drive to our manatee tour the next morning. We appreciated having a great breakfast each day.

Review and Tips 

Crystal River in Citrus County is quite busy during winter time due to the huge number of manatees in King’s Bay. It’s the largest gathering of manatees in North America. Everybody wants to get nose to nose with a manatee. You definitely spot them in high numbers.

The Three Sisters Springs

It's the perfect location to observe manatees along the boardwalk. Volunteers answer all questions and offer guided walking and birding trails. Birding is also outstanding around the springs.

Swimming and kayaking are allowed during the summer. Anyhow, there isn’t any access through the refuge. You'd have to come by boat or kayak to get into it. It can happen that you spot a manatee, but there are very view around in summer.

If you don’t like to swim in the river in winter, you can go on a kayak tour to get a closer look.
There are plenty of tour operators around Crystal River for swimming or kayaking with the manatees and also for diving into the cavern at Kings Spring. 

Must-Know Tips

Try to book a morning tour (Swim with Manatee Adventures), as you'll experience the most manatee activitiy then. However, prices may be slightly higher for the morning tours. Some offer pictures on a USB stick, a CD or online afterwards. Check the quality of the pics before you decide to buy them. Due to the many people and manatees in the water, the visibility and clarity aren’t as good as you may expect.

Facts About the West Indian Manatees

The manatees migrate from Kings Bay and the Gulf of Mexico to the different springs during winter to survive. They need a water temp above 68°F, otherwise, manatees get stressed by the cold and can die. These gentle giants move slowly but can reach up to 15 mph. Their skin is covered with barnacles in the gulf during summer and with algae in the springs in winter. They are an aquatic relative of the elephant. Manatees breathe every 2 – 4 minutes, during resting only every 20 minutes. A newborn calf is already 3-4 feet long and an adult in average 10 feet. The weight is on average 1000 pounds but can be even higher. Actually, a manatee could get up to 60 years old, but in the wild often less than 30 years.

These amazing giants don’t have any natural enemies, but the biggest threats are caused by humans.

  • They get injured by boat
  • Disturbed by humans
  • Loss their habitat
    (It was planned to use the land around the springs for building houses and to bottle the spring water. Thanks to all backers who prevented these plans!!).
