Batman was created in May 1939 and made his first appearance in Detective Comics #27. The Batcave is the secret headquarters and safe house of the Dark Knight. Throughout the decades a cast of recurring enemies have been introduced in various issues of comic books. The Batman villains are considered to be the greatest superhero rogues gallery in all of comics. Many of these super-villains have tried to find the secret location of the Batcave, can you?

Car parking and a small park with playground and barbecues is located at the posted coordinates. This will be the start of your climb to the Batcave.
A trail-head can be found by subtracting 203 and 138 from the decimal part of the final cache location. The trail to the cave is slightly overgrown but quite level once past the trailhead and easy enough to find your way. Bring along a torch to help find the cache. Once inside the cave please be careful to not disturb any bats that may be roosting in the roof.
