This site is full of historical items such as an Ice Age melt created gorge, the American Telephone Transcontinental cable, the U.S. military WWII redar research site, and a (lower than summit) great lookout rock. Friendly vertical well groomed trails. Highly recommend!!!

This a great easy vertical adventure near metro northwest Boston along groomed trails through the woods, with lots of interesting historical features such at the Ice Age carved Trophe Chasm (bordered with large granite boulders), and more modern items such as the ATT Transatlantic Cable, and a World War II era Air Force radar testing station. Well worth it in any weather, never crowded, trailhead parking. Highly recommend.

This is the northern terminus of the Nashua River Trail. It runs from this point all the way to Ayer, Massachusetts. The trail passes through J. Harry State Forest and is tree lined for a majority of its trajectory.

J. Harry Rich State Forest is a state-owned woodland just north of Groton. This is a beautiful woodland that has a network of wide-maintained trails and a selection of other trails for visitors to enjoy hiking, biking, fishing, and wildlife watching. The paved Nashua River Rail Trail borders the eastern side of the forest, and Pepperell Pond flanks the western side of it. The forest is teeming with all manners of wildlife, but in addition, it has many other quirky features; there is a charming bridge, a boat house, and then there are the glorious riverside views. There is plenty to occupy you in this forest.

Yes, for an easy and engaging loop, consider the Nashua River Rail Trail β Groton School Pond loop from Groton.

Another great option is the Groton School Pond loop from Ayer, which is slightly longer at 7.4 km, also with very little elevation change.
The trails in Lost Lake Recreation Area offer a mix of natural beauty, often winding through forests and alongside water bodies. You can expect peaceful environments, opportunities for birdwatching, and a chance to experience the local flora and fauna. Some areas might feature old-growth stands or scenic lake views, providing a refreshing escape into nature.
Many trails in recreation areas like Lost Lake are dog-friendly, but it's always best to check specific regulations for each trail or park section. Generally, if dogs are permitted, they should be kept on a leash to protect wildlife and ensure a pleasant experience for all visitors. Please remember to clean up after your pet.
Spring, summer, and fall are generally the most popular seasons for family hiking in the Lost Lake Recreation Area. Spring brings blooming wildflowers, while summer offers warm weather perfect for lakeside activities. Fall showcases beautiful foliage. Always check local weather conditions before heading out, especially for potential rain or early snow in higher elevations.
For a comfortable family hike, we recommend wearing sturdy, comfortable shoes and dressing in layers to adapt to changing weather. Don't forget essentials like water, snacks, sunscreen, insect repellent, and a basic first-aid kit. Depending on the season, a hat and rain gear can also be very useful.
Parking availability can vary by trailhead. Many popular recreation areas, including Lost Lake, typically offer designated parking lots. However, during peak seasons or on weekends, these can fill up quickly. It's advisable to arrive early, especially for popular routes like the BoundaryTrail, to secure a spot.
For families seeking a longer adventure, the Groton Town Forest Race 9.5 mile Loop offers a more challenging experience at over 20 km. While rated difficult, it provides a substantial distance for older, more experienced family hikers. Another option is the Nashua River Rail Trail, which is significantly longer and also rated difficult, suitable for very active families.
The Lost Lake Recreation Area is highly rated by the komoot community, with an average score of 5.0 stars. Reviewers often praise the peaceful atmosphere, the well-maintained trails, and the beautiful natural surroundings that make for an enjoyable family outing.
When hiking with family, always stay on marked trails and supervise children closely. Be aware of your surroundings, especially in areas where wildlife might be present. It's a good practice to carry a map or use a navigation app, inform someone of your hiking plans, and check weather forecasts before you go. In some Lost Lake locations, like Yellowstone, being aware of larger wildlife such as bears and bison is crucial, and hiking in groups is recommended.
