Inday Nelly Mystical Cave is located in Antipolo, Rizal, Philippines.   The interesting large cave is being maintained by Inday Nelly who, guided by a prophetic dream from her childhood, bought the large parcel of land land (450+ hectares) where the cave is located back in 1970 . The cave is being developed into a tourist attraction. Steps have been constructed at the cave entrance, the cave floor has been filled with earth to level it substancially and rudimentary electric lighting has been introduced into the cave for the tourists. Thus, it may no longer be a spelunker's choice destination but it still is a very good destination for educational field trips.  The cave has a rather predominant religious influence. Numerous natural rock formations in the cave have been interpreted as religious figures and said to have healing powers. Much like how mystical Mt. Banahaw attracts pilgrims, people go to this mystical cave to heal themselves.  How to get thereBest start point for this destination is the Katipunan Avenue and Aurora Boulevard Intersection in Quezon City. From this start point, go down eastward through Marcos Highway towards Masinag. At the Masinag intersection head on straight eastward and uphill towards Cogeo. At the Cogeo intersection, head straight eastward still for about another 3.5 kms until you see see a row of identical apartment buildings (formerly a motel but now the Sta. Eugenia College). Turn right into a wide dirt road at the first corner. About 2kms onward, after passing through a quarry area, carefully look for a signboard on the left side welcoming you to the site of the Mystical Cave.   Source:Waypoints.ph
