The sweltering heat of a Florida summer doesn't mean you have to be stuck indoors for months on end. After all, the best way to beat the heat is also lots of fun and great exercise: swimming! Nobody wants to spend every single day at the pool or a crowded local beach. Which is why these swimming holes in Florida are some of the best you can find in the state. Switch things up and keep it interesting by visiting as many of these alternatives as possible!

1. The Venetian Pool, Coral Gables

It might come as no surprise that the country's largest freshwater swimming pool is right here in Florida.

3. Grayton Beach State Park, Santa Rosa Beach

5. Weeki Wachee Springs State Park

9. De Leon Springs State Park

Guests can explore the underwater world at depths up to 30 feet in this state park located about 30 minutes from Daytona.

Address: 601 Ponce Deleon Boulevard, De Leon Springs, FL 32130.

10. Bahia Honda State Park, Big Pine Key
