Top 5 Caves in Massachusetts

Many hand built shelters on the way here! Showcasing many styles of shelter making and was very interesting to come across so many… the cave was small but a fun stop! Especially because the trail was adorned with hand built shelters!

The Trail Through Time is a two-mile bicultural heritage trail located within Acton's Nashoba Brook Conservation Land. This loop trail, which is also a part of the Yellow Trail, guides you through twelve different historic sites featuring stone structures from pre-historic, colonial, and industrial periods, including the Nashoba Brook Stone Chamber and remnants of early mills and farmsteads. The trail crosses Nashoba Brook twice on footbridges and traverses through wetlands, woodlands, and over historic stone walls. Visitors can access the trail from multiple entrances, with a main kiosk situated off Wheeler Lane within the historic Wheeler Farm area. This section of trail parallels Nashoba Brook from Wheeler Farm (and Robbins Mill) to the Potato Cave. Keep an eye out for beavers and other animals along this pretty section of trail, especially as you near the boardwalks by the potato cave. It can be quite muddy (sometimes flooded!) in the spring so make sure you have proper footwear.

The Nashoba Brook Stone Chamber is in the Nashoba Brook Conservation Area in Acton, Massachusetts, and is an underground stone structure commonly referred to as the "potato cave." This name originates from the belief that it once functioned as a root cellar. Excavations in 2006 support this view, indicating construction during the 18th or 19th century for food storage. However, some theories propose it was actually much older, positing it was originally a pre-colonial Native American ceremonial stone landscape structure. Local lore also suggests it provided shelter for 19th-century railroad workers. The restored chamber is part of Acton's "Trail Through Time," which highlights the historical use of the Nashoba Brook area

Dungeon Rock is full of history and mystery! In the middle of the 17th century, four pirates – one of them named Thomas Veale – sailed up the Saugus River and built a shelter in the area. Except for Veale, the pirates were caught by the authorities and sent back to England where they were sentenced to death. Veale hid himself and the treasure in a nearby cave where he died when the cave collapsed due to an earthquake in 1658. His treasure was never found. Today you can visit Dungeon Rock which was formerly known as Pirates' Rock by hiking along. Maybe you will find the treasure?

The Horse Caves are a series of rocky outcroppings that played a role in American history. During Shays’ Rebellion, Daniel Shays and some of his men supposedly took refuge in the Horse Caves after their defeat by the Massachusetts militia. They were also used by soldiers during the Civil War. Even if you're not a history buff, these caves are an interesting and unique geological feature to explore.
