Ralph Hill Park Trails is a 2 mile moderately trafficked loop trail located near North Billerica, Massachusetts that features a river and is good for all skill levels. The trail offers a number of activity options and is accessible year-round. Dogs are also able to use this trail but must be kept on leash.
White pine/oak forest that may provide suitable habitat for interior-nesting birds. The topography is varied, with high ridges and a steep slope down to the riverbank. The conservation area has considerable aesthetic appeal, with attractive river views and exposed bedrock formations. Also featuring prominently on the property are Winning Pond and a large beaver pond. Wetlands areas are located east of the beaver pond along Route 3 and just north of the larger portion of Ralph Hill Woodlot. Two vernal pools are also located on the property. The Town of Billerica and SVT collaboratively manage the Vietnam Veterans Park and Ralph Hill Conservation Area. Vietnam Veterans Park was the first park in the United States dedicated to Vietnam Veterans. The Middlesex House of Corrections formerly used the upper part of the property as a working farm that provided dairy products and vegetables to the prison.
Nice wide trails! Good elevation change and the water access for dogs. Woulda given 5 stars if it wasn't so close to Route 3 at one point, which made it very noisy.
The trails are well marked and the Sudbury Valley Trustees do a good job of trail maintenance. There are some trees across the trails, bikers need to beware of these obstacles. The walking is great, some up and down hill, but not difficult at all. There are several different loops you can do depending on how far you want to go. You can see the river, but the edge is mucky.
