Fringed by resorts and cottages, the cove offers calm waters for swimming and snorkeling and is one of Pagudpud's most visited coastal attractions.

Visitors can expect a curved white-sand cove with clear blue-green water, bordered by hills and lined with resorts, cottages and small eateries. The beach area is open for swimming, wading, sunbathing and photography with views of the Dos Hermanos islets offshore. Shallow areas near the shore are suitable for snorkeling when sea conditions are calm. Facilities are concentrated along the beachfront access road.
