New Jersey may not be home to massive glacial caverns but we still have a few caves hidden away. Some are easily accessible while others are for the more adventurous. Either way, there is a cave on this list for almost any taste. What we lack in stalagmites, we make up for with charm. Here are some of the most otherworldly caves in New Jersey.

1. Crooked Swamp Cave, Layfayette Township

The cave at Crooked Swamp Cave Preserve is located on a much larger wildlife preserve that includes a Great Blue Heron rookery. The cave itself is not open to the public following a 1982 tragedy but can be accessed by advanced spelunkers through guided tours offered via the New Jersey Cave Conservancy. It's one of the most remarkable NJ caves.

2. The Caves At Jenny Jump State Forest, Great Meadows

There are several small caves in this state forest, many open to adventurous hikers. Faery Hole Cave is the largest of the New Jersey caves within Jenny Jump State Forest the park and many interesting artifacts have been found there. Significantly smaller is Fairly Low Cave which lives up to its moniker. Though the cave is over 160 feet long, it is only four feet high.

3. Sybil's Cave Park, Hoboken

A visit to Sybil's Cave Park will allow you to see a historic man-made cave with a natural spring. One of America’s first big murder mysteries centered around this particular cave; the body of a young store clerk was found there in the 1840s. Edgar Allen Poe went on to use it as the basis for his short story, "The Mystery of Marie Rogêt." Sybil's Cave is one of the most interesting caves in New Jersey.

4. Sterling Hill Mine, Ogdensburg

The easiest-to-access underground adventure in New Jersey, Sterling Hill Mine is open regularly for tours. Located in Sussex County, The Mine is surrounded by fossil and rock discovery centers, making it a great place for family fun. The Museum of Fluorescence is one of many amazing attractions located on the mine’s grounds and it is home to one of the largest fluorescent mineral collections in the world. You will absolutely love exploring Sterling Hill Mine, one of the most otherworldly caverns in New Jersey.
