People are very poor on this island. However, they charge astronomical prices for anything. Not worth buying anything, at least, I did not find anything worthy. Quite a few of officially looking drivers were offering rides to the beaches ay the port for $20-25 per person roundtrip. Once we went out of the gates, the prices were drastically lower. We picked a guy who offered $50 for 4 of us to the beach and back. The beach was nice, it had shady area, the water was clean and nice. We tried snorkeling, but it wasn’t the best spot for it.
I can't find the business card of that driver now, but if I find it, I'll post it here. He was great!
