Mount Dora, Florida

Blue Spring State Park has repeatedly won the best state park in America award. There are several reasons. From March through October, the big blue spring and its mile-long stream to the St. Johns River is a peerless subtropical delight for swimmers, scuba divers, tubers, canoeists and fishermen. Rentals are available. From November into March, it’s a haven for manatees. The crystal-clear water makes it possible to actually see the gentle giants (as much as ten feet long and a thousand pounds) as they swim slowly in the deep 73° water. Nearly a mile of boardwalks has been built along the blue springs stream that showcases not only the manatees, but some of America’s most spectacular native subtropical vegetation. A full-service campground is available, including separate campsites for backpackers. There are six rental cabins.
