I clicked on the link. It detailed how you can sign up to be led on a walk through the swamp. Not on boardwalks, but in the water. The particular one I was looking at was rated 5/5 difficulty and was a 5 mile adventure through “a couple inches to a couple feet of water.”
We found ourselves surrounded by lush shades of green, the silence of a dirt path under our feet, and a view backlit by rays of the setting sun, flooding through the tree branches. The path we hiked started out as a typical Florida hike: flat land running along a river, mangrove trees with their roots dipping into the water, signs warning of alligators, and the forest floor covered in greenery, teeming with life.
