Hillsborough River State Park in Thonotosassa was opened to the public in 1938 as one of the original state parks developed by the Civilian Conservation Corps (CCC). This 3000-acre park occupies land on both the north and south banks of the Hillsborough River. A CCC-built suspension bridge over the river connects the 2 areas. The section of the river that flows through the park contains several small rapids, including a class 2 rapid, as it flows over limestone outcroppings. River rapids are a rarity in Florida.

Fort Foster State Historic Site is located within the park. The original fort was built in December 1836 by Col. William S. Foster and his 430 men. Its purpose was to defend the Hillsborough River bridge crossing during the Second Seminole War and to resupply soldiers in the field. The fort that occupies the site today is a reproduction. Public access to the fort is restricted to Thursdays at 10:30a.m. when a ranger-led tour is conducted. Two times each year there is a living history reenactment. The Fort Foster Rendezvous takes place in January, and the Candlelight Experience at Fort Foster in December. There is also an interpretive center containing over 100 artifacts found at the historic site. The center is open daily from 8a.m. to 5p.m.
