I read a previous review that said the cavees were nothing special, just caves. I guess that's one point of view. None of them are Carlsbad Caverns, but they are interesting, generally easy to explore, and each has its own personality.
Rebecca's Cave is a small entry walk-in to a chamber where you can see the grave of an 18 month old girl who died here when her parents took shelter during a hurricane. Most of the caves were once - or still - a hurricane shelter.
Bat Cave once sheltered bats, but none were present during my visit. It requires stepping over some rough limestone, but nothing too serious.
Great Cave requires climbing three ladders and maneuvering over several outcrops of rough limestone. It's a good idea to wear closed shoes, long pants and gloves.
Peters Cave requires climbing rough stairs about 140', or climbing about 3' down the stairs from the top. The entry is fairly low (3-4'). It is the one cave currently used as a hurricane shelter.
Skull Cave is very easy to access and the opening is roughly in the shape of s skull.
The most unique - and most challenging - is Nani or Chandelier Cave. The entrance is small and requires climing over rough limestone to enter a tricky chamber with stalactites and stalagmites. Wear sturdy shoes, long pants, knee pads and gloves. The unmarked access road is across from the Mosquito Control facility.
