Kings Bay, protected by the refuge, contains over 70 individual springs.
The refuge protects 20 named springs, including the Three Sisters Springs complex.
Manatees are strictly protected under the Marine Mammal Protection Act and the Endangered Species Act.
The refuge does not have direct boat launch access; visitors must use local commercial or public ramps to access the bay.
Manatees can consume up to 10-15 percent of their body weight in seagrass daily.
The springs are discharge points for the Floridan Aquifer, one of the most productive groundwater systems in the world.
Crystal River National Wildlife Refuge is the only refuge in the United States specifically created to provide sanctuary for the Florida manatee. It protects the primary warm-water springs in Kings Bay, which maintain a constant temperature of 72 degrees Fahrenheit year-round. This thermal consistency makes the site a critical refuge for manatees seeking shelter from cold Gulf of Mexico waters during winter months. The refuge manages over 80 acres of land and water, including several islands and spring heads. Visitors can access interactive exhibits at the visitor center that detail the regional ecosystem and conservation efforts. The area is part of a complex network of springs that serve as a globally significant habitat for the West Indian manatee. Non-motorized watercraft are frequently used to navigate the surrounding bay areas to observe wildlife in their natural habitat. The site is actively monitored by the U.S. Fish and Wildlife Service to balance tourism with stringent animal protection regulations.
The boardwalk overlooks at Three Sisters Springs provide the clearest views of the spring run and manatee aggregation areas.
Observe manatees from a distance and avoid touching, chasing, or blocking their path.
Visit during the winter months for the highest density of manatees, as they congregate in the warm springs to avoid cold ocean temperatures.
Use polarized sunglasses to significantly improve visibility through the water's surface.
Do not attempt to feed, give water to, or ride the manatees, as these actions are illegal and harmful to the animals.
Some areas within the refuge may have temporary closures or restricted access during peak manatee season to protect the animals.
Maintain a quiet demeanor near the water to avoid disturbing wildlife; strictly follow all 'no wake' and 'manatee sanctuary' zone markers.
