The Bay State is filled with opportunities for exploration and adventure wherever you go. And while caves always have quite the allure, there’s a man-made cave in Lynn that has a fascinating origin story. This secluded cave in Massachusetts can be reached via a hike in Lynn Woods Reservation and it is one place that is worthy of an adventure. With legends of pirates gold, soaring towers, and incredible views along a hiking trail, the Lynn Woods Dungeon Rock is just one of many attractions to this incredible journey.

The 2,200-acre Lynn Woods Reservation, the second-largest municipal park in the country, is located in the city of Lynn in Essex County.

This seemingly normal pile of rocks holds a surprising twist and a wild story. Who would have guessed this trail could take visitors on a wild treasure hunt and walk in the footsteps of pirates?
Legend has it that, in the 1600s, a pirate hid his loot in a cave at the rock but an earthquake destroyed the cave, burying him and his treasure. In 1852, a man by the name of Hiram Marble bought the rock and dug out a new cave as well as a tunnel that remains today.

Visitors can make a request with the park rangers to open the steel door to the cave for a few hours during the warmer months. The door can be found within the rock crevice. If you're keen on exploring the cave, remember to bring a flashlight. To learn more about Dungeon Rock and the cave, read our previous article about exploring the Dungeon Rock cave.
