U-ugak Beach and Cave is located at Mauban, Quezon, Philippines.

U-ugak Beach and Cave is a place where the sea meets the mountain. Untouched by civilization, this idyllic place is about one and a half hour travel by boat from Mauban Port to Barangay Cagsiay III. The crystal clear water teems with different species of fish, shells and corals. Various plants grow beside the rocky mountain which is ideal for hunters. But hunters will be delighted with caves not on mountain tops, but under! One has to swim deep to enter the caves and marvel where the dry sands come from.
