Geographically, the composition of Siquijor island is mostly limestone rock material. Excepting the coastal plains of Lazi and San Juan, most of the interior of Siquijor island is either hilly or mountainous. The highest point, roughly in the middle of the island is Mt. Bandilaan which is 557 meters high. Scattered throughout the island is a wealth of caves – some small, some large, but very few visited by tourists. With more than forty caves, there’s spelunkering enough to do for weeks!
A few of the larger caves are noted on most tourists maps, but to find the lesser known ones you need either organise a guide or take your time and ask around when you get to the local communities.
A brief rundown of the names of the caves, and where you may find them:
Ilihan Cave with Antique Coffin
