The small Visitor Center at Halibut Point State Park is located close to the quarry pond and the walking trails.

Dogtown Commons

Highlight • Historical Site

Although this area is perhaps better known for the Babson Boulders and their quirky phrases, Dogtown's history extends far past the Great Depression. Dogtown was originally known as the Common Settlement when it was settled in 1693. Within a few decades, there were about 60 to 80 homes in Dogtown, and by the mid-1700s through the American Revolution, there were as many as 100 families in Dogtown. Although none of these early homes remain, you can still make out cellar holes from this period in this area. Babson mapped and numbered these holes in the 1930s with caved rocks that you can see today.

Dungeon Rock

Highlight • Cave

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?

There are many trails connected to hike up this Holt Hill from all direction in Andover and North Andover trails. It offers a spectacular view on clear days including the Boston skyline. From here hikers/walkers can take blue loop trail to climb the next hill called Boston Hill and back. The blue trail is my favorite to walk for over 5 miles stroll (OUT AND BACK).
