Florida Everglades and Big Cypress National Forest

The last time we were in the area staying at Midway, the loop was closed to traffic beyond the paved sections at each end. As Roadpilot said, it's often underwater, so checking ahead would be a very good suggestion. If it's open, from what I recall there weren't any overhanging trees, but the unpaved section is very narrow, and could present a problem with a motorhome if there was traffic coming the other way.
