This is the day that captures Bocas in one boat trip. Cross to Dolphin Bay to watch resident dolphins, snorkel the shallow reefs at Coral Cay (with lunch served over the water), and land on the powder-white beaches of Cayos Zapatillas, two protected cays inside Panama’s first marine national park. Warm turquoise water, easy reefs and classic Caribbean scenery — the single best introduction to the archipelago.
