Four major springs are located within the forest, making it a great place to swim, dive, snorkel and canoe. Alexander, Salt, Juniper and Silver Glen Springs all have wonderful swimming areas, and snorkeling and spring diving give the visitor an underwater view of a unique ecosystem. In addition, all of the springs have runs (streams), which offer some of the best canoeing in Florida. Crystal clear water flows swiftly through tropical wilderness on all the spring runs, and they vary in length from one to seven miles. For a longer canoe trip, the Upper Oklawaha River offers the visitor a chance to paddle a real Florida blackwater river. The entire canoe run takes two full days; with four different take out points along the river the trip can be reduced. Eleven developed campgrounds offer the camping enthusiast unlimited options. Ten of the developed sites offer full RV hookups, and the campgrounds range in size from 14 to 197 individual campsites. Bathroom facilities with hot showers, picnic areas and concessionaires are available at most of these facilities. For those who wish to rough it, primitive backpack camping is available throughout the forest, with a permit from the main office. Several of the trails also have primitive campsites with water along their paths. The other recreational opportunities in Ocala National Forest include 100 miles of horse trails, a twenty-two mile bicycle trail, fishing and limited hunting with permits.
