After a drive through the rainforest to Golfito, we are picked up by a boat and taken to Playa Cacao. Here we begin paddling up the coast in our lightweight kayaks, with time to observe the rainforest and stop at uninhabited beaches for a swim in Golfo Dulce. The warm (85 F.) sea is very calm in the morning, giving us a good chance to see dolphins. We can leave our backpacks, cameras or water bottles in the boat, which follows at a discreet distance. Whenever we decide, our kayaks are attached to the boat for a fast fun-ride back to Playa Cacao.
