If a trail has a paved lot, a sign, and a bathroom, you're going to share it with fifty other people that same morning. That's fine sometimes. It's not the whole island.
Some of the best hikes here don't have a real trailhead at all — just a wide spot on the shoulder of the road, maybe a faded ribbon tied to a branch, and a path that locals have been walking for years without anyone putting up a sign.
These trails don't get maintained the same way. Roots, mud, no railings, no map at the entrance. You need real shoes, a full water bottle, and the sense to turn back if the weather turns.
What you get in return is the island the way it looked before it was a destination. No crowd noise, no waiting for a photo spot to clear, just trees, birds, and wherever the trail actually decides to take you.
Ask around before you go. The good ones aren't on the tourist map, and that's exactly the point.
