Playas del Coco, Pacific coast beach in Guanacaste Province, Costa Rica.

Playas del Coco is a beach town in the Sardinal district of Carrillo canton, Guanacaste, on a curving bay of the Gulf of Papagayo. A small rounded island covered in dark green vegetation sits offshore near the centre, and many small white boats are moored across the water. Dense trees and low buildings with reddish and pale walls line the shore behind the beach.

Playas del Coco emerged about 150 years ago when the first settlers arrived to dive for pearls and fish artisanally; logging was also profitable. From the 1930s it drew vacationers, and in the 1960s locals offered rudimentary cabins and sodas. Don Claudio Rojas opened the Casino Playas del Coco in the late 1950s, and the 1995 opening of Guanacaste Airport accelerated residential tourism.

Playas del Coco is where the celebration of the Virgen del Mar began, rooted in the story of local sailors who were lost at sea; the feast was later adopted by Puntarenas. The town's name is also remembered in Héctor Zúñiga Rovira's song "1930", about vacationers travelling to Guanacaste when the horse was the main means of transport.

The dry season runs from November to May, while late May to early November is humid with intermittent rain; October is the wettest month. Average temperature is around 27 °C. The town lies about 20 minutes from Guanacaste Airport and 40 km from Liberia, making it a base for diving, sailing and sport-fishing trips.

Playas del Coco is the birthplace of the traditional celebration of the Virgen del Mar, which began with a story of local sailors lost at sea. The feast is now held in Puntarenas, which adopted it as its own.
