Being an archipelago, Romblon has several beaches and dive sites. Among its best white sand beaches are Bonbon, Cobrador and Tiamban Beach in Romblon, Macat-ang, Tabunan and Tambak Beach in Banton, Lunas and Bignay Beach in San Jose, and Cresta del Gallo in San Fernando. The sea surrounding Cresta del Gallo is a famous diving site teeming with marine life.Romblon is also home to the only known blue hole in the Philippines in the town of San Agustin. The entrance to the blue hole is a 6-metre (20 ft) wide volcanic chimney, which drops for 20 metres (66 ft) before opening up into the massive chamber below with a total depth of 32 to 40 metres (105–131 ft).
Mount Guiting-Guiting in Sibuyan, the province’s tallest mountain, is considered as one of the most difficult climbs in the Philippines, and is thus a major destination of local mountain climbers because of its steep and jagged summit. Another a suitable place for hiking and trekking is Mount Payaopao is Tablas. Meanwhile, Banton’s Guyangan Cave System, an Important Cultural Treasure, is where the Banton Cloth — the earliest known warp ikat textile in Southeast Asia — was found in 1936.
