Romblon Province, south of Marindugue consists of three main islands, Romblon, Tablas and Sibuyan together with about 15 smaller islands. The little town of Romblon is its undisputes centre, officially called "Romblon on Romblon in Romblon". Fittingly, the motto of the local is "We’re rumblin on" and they seems to "rumble on" very happily. The place is one of the prettiest in the Philippines with panoramic views reminiscent of the Meditterrance. Romblon island is the country’s main source of marble. Tablas, though the largest of the Romblon province is the least interesting. The interior of the island is mountainous and in places very bare. The mango-shaped island of Sibuyan, third largest of the Rombon Group, consists principally of the Mount Guiting-Guiting massif. Reaching a height of 6725 ft, it is scarely in the alphine class, nevertheless it is considered a very difficult mountain to climb, and was not conquered until 1982.
