The road continues north from here to the beaches of Punta de Palma, a popular weekend getaway for folks from Puerto Barrios [1] and where a sliver of sand meets the Caribbean Sea.
There are some refreshment stands but little else here. Although locals might try to talk it up, you’ll probably be very disappointed. If you really want to hit the beach, there are some better options near Lívingston [2] and across the bay at Punta de Manabique Wildlife Refuge [3].
