Wear better shoes than flip flops. There are rough trails and they are continuously overrun with jungle. Not sure if there are actual caretakers to the property once owned by the later actor Errol Flynn. Portions of a ruined resort, as well as Flynn's home/pool are still visible and accessible, but beware of dangers due to rotting wood, hornets nest...A "rasta" makes his home somewhere on the island, so don't be surprised if he emerges from the vines. He may try to sell you something or trade.
