It is separated from the Philippine Sea by the Caramoan Peninsula in the north; and is separated from Albay Gulf in the south by a chain of islands including Batan Island and Rapu-rapu Island.

It is about 3,070 square kilometres (1,190 sq mi) in area, with 80% of its area between 800 metres (2,600 ft) and 1,200 metres (3,900 ft) deep.

[1] The gulf is home to 480 fish species, and annual fishery production in 2004 amounted to some 20,000 MT, making Lagonoy Gulf a major fishing ground in the Philippines.

Coral reefs, seaweed/seagrass beds, and mangroves form the critical habitats for gulf's ecology.
