The best dog-friendly hikes and walks in Great Brook Farm State Park

Camp Acton is a small rustic campsite run by the town of Acton. There is no running water on the campsite, but there is a portable toilet. The sites must be reserved in advance by call the Town of Acton's Recreation Department at 978-929-6640.

The Lookout Tower is a fantastic viewing area overlooking the expansive wetlands. There is a small telescope available to observe the local wildlife. If you visit in the spring, you'll see plenty of beautiful American Lotus plants in bloom scattered across the marsh.

This trail is an excellent paved scenic route, ideal for walking, running or biking. Along the way are beautiful views of the lake, which is also a great place to stop and take a nice break. In the springtime, water is often running over the trail, so plan to get a little wet.

The Great Meadows National Wildlife Refuge is a 12-mile wetland conservation area and home to a large variety of birds and turtles. A well-maintained trail circles the pond's perimeter with marshes and beautiful lotuses that bloom in summer. There are a few short trails and a path leading to the Concord River with benches, which are ideal for relaxing and taking in the scenery. It's a favorite spot for families and photographers, with an observation tower that provides excellent views. Parking is free but limited, with clean restrooms (closed in winter) and a port-a-potty available.

Wheeler Farm, located in North Acton, Massachusetts, is a historic site featuring the remnants of an 18th-century farmstead and mill complex established by Thomas Wheeler Jr. in 1732. The property includes the foundations of a gristmill and sawmill that utilized water power from Nashoba Brook. These mills were integral to the local economy, processing grain and lumber for the community. The site is part of Acton's "Trail Through Time," a heritage trail that highlights both Native American and colonial historical sites. Visitors can explore the Wheeler Farm foundations and nearby Robbins Mill ruins, gaining insights into early industrial activities in the region. The area is accessible via trails that connect to the Nashoba Brook Conservation Land, offering opportunities for hiking and historical exploration and is the main trailhead for the "Trail Through Time."

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.

Spring Hill Conservation Land encompasses 213 acres of preserved wildlife habitat and is a part of Acton's largest protected natural area, connecting with Camp Acton, Nashoba Brook, and Robbins Mill conservation lands to form over 400 contiguous acres. The main trail through the area is a yellow-blazed loop trail that spans 2.5 miles, offering mostly level terrain with some stony stretches. Watch out for slippery rocks, mud, and roots, which can be covered by leaves in the fall! Two blue-blazed secondary trails intersect the main loop, allowing for shorter circuits. Red-blazed connector trails link Spring Hill to adjacent conservation areas (namely Camp Acton and Nashoba Brook). The Bay Circuit Trail also traverses Spring Hill. It is marked by white blazes and BCT logos, connecting to Nashoba Brook Conservation Land. There are clusters of stone piles scattered in the area that believed to be of Native American origin, possibly serving ceremonial purposes. These are highlighted along the trails, with educational panels providing historical context. There are also old stone walls that date back to the colonial era. Visitors can access Spring Hill via entrances at the cul-de-sacs on Spring Hill Road and Jay Lane, with parking available.

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
