Playa Blanca is the best beach in the area, partly due to its distance from the outflow of the Río Dulce and the heavy pollution generated by the residents of Livingston. The sand here is a bit whiter and softer, and the water a bit bluer than you'll find closer to town. This is actually a private beach (hence the admission charge), and to get here, you need to sign up for a guided tour or hire a boat through ASOTRANSLALI (tel. 502/7947-0870). I recommend going with a guided tour with one of the local tour agencies for around Q120 ($16/£8). These tours usually include lunch and a visit to Los Siete Altares.
