Cycling there is fun, especially with a mountain bike. The trail is a mix of dirt and sand, with uphill and downhill sections, but it's scenic and deserted. It's best to go in the morning; the afternoon would probably be better as it's on the eastern side of the island. During the rainy season, a freshwater stream flows into the sea, but the path might become more difficult.
Don't go here. The journey is far too strenuous only to end up on a littered beach. The beaches on this island are (still) all deserted, beautiful, and much easier to reach, so why come here? Save yourself the time and go to a different beach.
