Because it's hidden from the main road Playa Pirata flies under the tourist radar and is basically a private beach for the lucky property owners at the west end of Bahia Feliz. There's no facilities, not much sand at high tide and the afternoon sun is blocked out by the cliffs. However, Playa Pirata is as close to a secret sandy beach as you get in this part of south Gran Canaria and the walk down is a lot of fun (the walk back up less so). 

Get to Playa Pirata via the steep steps running from the cliff top in San Agustín or by walking and wading along the shore from Bahia Feliz.

This beach is also known as El Besudo.
