South of RÃo Claro, Playa San Josecito is one of the longest stretches of white-sand beach on this side of the PenÃnsula de Osa. It is popular with swimmers, snorkelers and sunbathers, though you’ll find it crowded at lunchtime since it's the favorite post-snorkeling picnic spot for tour companies coming back from Isla del Caño. Watch out for capuchin monkeys!
