The former RV hotspot is now once again a great, quiet (in the off-season) beach. Camping is prohibited and police check that this is being observed. Beautiful bay with fine sand and beautiful palm trees, surrounded by rock formations in yellow and black. Brilliantly beautiful. In the high season the bar is probably open too.
