The Baltak Fishery Reserve is located in Balubad, Atimonan in Quezon Province. The Baltak Fishery Reserve is an artificial reef based marine sanctuary, constructed and managed by a local fisherfolk organization and fully supported by the Local Government of Atimonan. The original cement structure was installed underwater in 2003. Currently, the reserve has seven concrete pyramid structures, the latest of which is a 17 foot high, eight 8 layered structure. The submerged concrete surfaces are now home to a number of coral species, sponges, algae, and bivalves. Scores of red snappers with size ranges from 1-5 kilograms dominate the area, while hundreds of jacks of differing sizes, graceful batfishes and marching pompano accompany divers visiting the area.

It is traversed by the Maharlika Highway, which extends up to Bicol Region that links the regional and provincial movements to Manila.
