Interstate 10 runs through a region of uncommon Florida topography and geological features in the Northwest region of the state. Those who take the time to veer off the beaten path are rewarded with wilderness unparalleled and incredible opportunities to explore by foot, by bike or by paddle. On the surface, the area's main city of Marianna is all antiques and 19th-century relics. St. Luke's Episcopal Church, scene of the Civil War Battle of Marianna, still stands. Beneath the town, caverns (both water-filled and dry) invite exploration. Tours at Florida Caverns State Park reveal limestone stalactites and stalagmites, and you also can camp and fish here. The multi-use trails are popular with horseback riders, cyclists and walkers.
