This is a lovely area on the coast south of Manila. Here you will find Anilao (Mabini) which is famous for its dive sites, Taal Lake and Volcano - said to be the lake within the lake, old churches and houses dating back to the Spanish times in Taal, Calaca and Batangas City, and the Batangas International and Container Port. There is mountain trekking - in Mt. Maculot and in Mabini and Nasugbu towns. There are fresh-water beaches in the towns around the Lake -- San Nicolas, Agoncillo, Cuenca, Balete, Tanauan and Talisay. Salt-water beaches abound in Matabungkay (Lian town), in Nasugbu, in Calatagan, in Calaca, in Lemery, in Taal, San Luis, in Bauan, in Lobo, and in Laiya (San Juan town). There are also several island tourist destinations, namely: Tingloy, Verde Island, Ligpo Island, Sombrero Island, and Fortune Island. There are also Industrial Parks and various manufacturing industries dotting the shoreline. http://wikitravel.org/en/Batangas
