About half an hour from Sibaltan towards Taytay, the road on the way to the Ille Caves has some great view points over vast mangrove forests and islands out in the bay. The cave is an archeological site that is only slowly being uncovered and will probably revel many more exciting secrets. A local tour guide takes you on a short walk through the caves, which are impressive both from the inside and the outside. For those daring and fit enough (and wearing proper footwear!), there is a short climb that leads to the top of the cave, from where there is a stunning view into the valley.
