Blue Spring State Park’s spring run in Orange City is scheduled to close to swimming and other in-water activities on Sunday, Nov. 15, as it becomes a winter refuge for manatees.

Saturday, Nov. 14, is the last scheduled day for swimming, though Florida Dive Company advises visitors that an early arrival of manatees could move the closure forward. Visitors hoping to swim should check the water status before making the trip.

Once the seasonal closure begins, swimming, tubing, diving and paddling in the spring run will not be available. The park itself remains open from 8 a.m. to sunset, including its boardwalk viewing areas along the run. Blue Spring’s water stays near 72 degrees, drawing manatees seeking warmer water as the St. Johns River cools.

Visitors need a day-use reservation before arriving, including Florida State Parks annual passholders. The reservation requirement began July 15, according to Friends of Blue Spring State Park. Reservations can be made up to 60 days ahead, with same-day bookings available if space remains. There is no separate reservation fee; standard admission is $6 per vehicle for two to eight people.

Save the reservation barcode on a phone or print it, and annual passholders should bring their pass. A reservation guarantees one entry during park hours, but reentry depends on capacity. Campers can use their overnight reservation as entry confirmation.

The winter closure applies to the spring run, not the entire park. Florida State Parks also has a separate notice regarding the French Landing boat ramp and canoe and kayak rentals and launches, so visitors planning a boating trip should check the current park notice before traveling.

Blue Spring State Park is at 2100 W. French Ave. in Orange City. Florida State Parks lists April 1 as the normal start of swim season, although reopening can be delayed if manatees are still using the spring.
