Geocache Name:

Manunka Chunk Tunnels (GC82B5)

Difficulty/Terrain Rating:


Why this is the Geocache of the Week:

As the end of October nears and Halloween draws close, the air has a certain chill to it. The trees turn into skeletons of their former selves. At least, for me, Halloween is one of the best times of year and always puts me in the mood to visit spooky or haunted places. The Manunka Chunk Tunnels in New Jersey have been abandoned since sometime in the early 1900s—well, let me clarify: abandoned from their intended use. Intrepid urban explorers and geocachers have been visiting these tunnels for years. In order to earn your smiley, you’ll have to summon loads of bravery, don a sturdy pair of mud-proof boots and journey through darkness. Sounds like a perfect fall adventure to me!
