The island lies about east from the southern part of
Mindoro Island. The northern tip of Tablas is about from
Romblon Island.
Mount Payaopao (also known as
Tablas Summit on old maps) at the northeastern extremity of the island, is the highest peak on the island at high and the second highest in the province (after
Mount Guiting-Guiting). A wooded central range of hills traverses the length of Tablas. The west coast is formed by the western slope of the central mountain ridge, which is narrow and well defined. The summits in the middle of the island are 1,600 to 2,000 feet high. In the center of the island is
Bitaogan Peak, high, which appears as a rounded knob from east and west and sharp from north and south.
Mount Lunas, at the back of Looc Bay, is a black ridge high, long and rounded from east and west and sharp from north and south; with it the range breaks off to the low pass from Looc Bay to the town of
Alcantara on the east coast. The southern part of Tablas is a group of many sharp conical hills, all bare and grassy except
Malbug Hill, high, and
Calaton Point, high, on the east coast, which are dark and wooded. The shore line is largely mangrove, with many beaches of coral sand and some limestone cliffs. The shore reef is continuous except off Guinauayan Point. Cabalian Point, the southern extremity of Tablas Island, is low and sandy and hard to distinguish at night, a lighthouse was built during the American Colonial period. ==Education==
