The area is access sensitive!
Park on the side of the road, at the GPS point you should see a hole in the foliage, that leads to a muddy path. Use it to climb up the hill till the cave. There are a lot of loose rock in the cave and the low part of the routes are pretty crumbly, please do not make this area overcrowded. In case of rain the access path can be very slippery and sometimes even not practicable at all.
