Welcome to Playa Blanca
The beach is located about 20km southwest of Cartagena, on the Isla de Barú. It's usually a stop for boat tours heading to the Islas del Rosario. Beware: when the boats arrive, peddlers descend in their droves, offering everything from beach chairs to massages (most of them ridiculously overpriced). Keeping these folks at bay can be an irksome challenge. The only thing worth buying is cocada, a sweet coconut treat available in a variety of flavors.
Playa Blanca is also good for snorkeling – if you can see past the jet-skis.
