Exploring Bohol Caves
Bohol Island is made up of extensive karst (limestone) formations, such as sinkholes, ravines, the curious Chocolate Hills, and a large number of caves, many of them unexplored. It is considered by most as a cave country and got its name from the word “buho”, meaning “hole” from which spring water usually gush forth.
To date, there are more or less 1,400 caves that were discovered throughout the island. The caves are often found near coastal towns of the island with a few situated inland yet near to rivers and streams. The caves in southwestern and northwestern Bohol are made up of Pliocene limestone, and tend to be narrow, long, and wet; while those in southeastern Bohol are Miocene limestone that tend to be larger, deeper and drier.
During cave explorations, one may come across streams whose source is a hole in the ground, only to flow a few kilometers further on and disappear underground then gush forth again in the distance. This is a sign that caves exist in the area.
The underground world of the caves already explored was found to be beautiful, with astounding stone formations called stalagmites and stalactites and ponds. Many bizarre invertebrates like the albino crabs were found. They evolved and adapted to their dark environment. Bats inhabit most of the caves though.
Most of these caves were used as hideouts during wars. Some are easily accessible yet others need climbing equipments and climbing expertise in order to enter. Some caves are dangerous in the rain as water levels inside may rise up rapidly. For the 1st timers, it is highly advised that they seek guidance and proper orientation from local cavers to avoid untoward accidents.
Equipments used are main and back-up lighting systems, to ropes, slings, carabiners plus other technical gear. But these depend upon the cave to be visited so it is quite important to have expert guides during each trip.
Fairly a new sport in the Philippines, it is considered with suspicion for some who hold superstitious beliefs regarding the caves. Some town officials and local residents may also be wary of these trips believing that cavers come for known Japanese treasures.
Surveyed and mapped caves in Bohol were found to be moderate in size and with ponds. Others show severe earthquake damage particularly in Guindulman town. Most caves are vertical drops that lead to horizontal passages, many of which are interlocking, and need climbing equipment and require experience. Some thrilling passages can only be entered by submerging oneself underwater.
Several caves are within the ancestral domain of Eskaya tribe, which covers portions of Guindulman, Duero and Bilar. Cavers have to get permission from tribal leaders before exploring, for failure to respect tribal customs and traditions could lead to these areas being closed.
Spelunking / Cave Exploration
One of the many crystal-studded passages within the cave's maze has an underwater route leading to dry land and was often used by Dagohoy and his men to escape the clutches of the Spaniards. The largest cave, however, is Sudlon Cave, nestled in a lovely mountain environment and is home to a huge population of bats.

The Buhong Tiawan Cave is located one and a half kilometer from the town center of Antequera, Bohol. The entrance of the cave can be found in the wall of a limestone hill and to reach it one has to walk one kilometer through dense vegetation.

In the annals of history, this cave served as a hideout of the locals during the Japanese occupation. At present, the cave is the home of birds and bats.
The Hagakgak Cave is located two kilometers from the center of Antequera town. The cave can be reached via a dense trail whose entrance is estimated to be 15 meters wide at the base of a sinkhole. The cave is literally undisturbed and is difficult to maneuver because the inside can be wet and muddy at times. There are portions where one has to pass thru narrow passages in order to enter a cavern where majestic formations of stalagmites and stalactites can be viewed. The rare albino crabs of the species sundathelphosa Filipina and fishes have adapted themselves to this dark habitat.
The Inambacan Cave is located two kilometers from the center of Antequera town and is more accessible than the Hagakgak and Buhong Tiawan caves. The caves’ special feature is the cavern with small stalactites and stalagmites which is often submerged in flowing water. The water may go over 1.20 meters deep where only a mere 30 centimeters of space remains before the ceiling. Local guides are necessary if one goes spelunking in the area.
The Antequera Cave is located in a village of Antequera town. The cave, where a summit pit is grown over with ferns, is known to be the home of phytons. It is otherwise called as the “snake pit”. The snakes feed on rats from the nearby fields.
