The top entrance is next to a field but has a more complicated walk-in (2019, from road side pull-ins to the south) due to the direct route below the farm being clogged up with rubbish. The bottom entrance emerges in dense jungle with site 2100 about 50m further down.

This is a through-trip in walking-size passage and an archaeological site where a few flints indicate that the cave contains palaeolithic remains. These are summarised in Ruiz Cobo Jesús and Muñoz Fernández Emilio et al, 2009.

Red marks near the floor were recognised in 2018 prompting a full documentation session by Spanish archaeologists on 11th April 2019. 3D laser scanning and photogrammetry were used to survey the cave and record the marks. One set of marks were found under a large block at the southern entrance where, the only way to view them was to crawl in and lie on your back.
