Blue Hills Reservation

Blue Hills Reservation is the great outdoors escape valve for Boston families who don't want to drive two hours to the mountains. Located 15 minutes south of downtown in Milton, the 7,000-acre reservation has 125 miles of trails, a freshwater swimming pond, a wildlife museum, and the highest point in the Greater Boston area — all completely free.

The most popular family hike is the Great Blue Hill summit trail. At 1. 5 miles round trip with about 500 feet of elevation gain, it's challenging enough to feel like an accomplishment but manageable for kids 4 and up (and toddlers in a carrier).

The Eliot Tower at the summit is a stone observation tower with 360-degree views: the Boston skyline to the north, the Blue Hills chain to the south, and on clear days, Mount Monadnock in New Hampshire. Kids love climbing the tower, and the sense of achievement at the top is real.

Houghton's Pond is the summer destination. A spring-fed freshwater pond with a sandy beach, lifeguards (seasonal), picnic areas, and restrooms. The water is clean, relatively warm by mid-July, and shallow near the shore — ideal for young swimmers. The beach area gets crowded on summer weekends, so arriving before 10 AM is strongly recommended. There's no admission fee.

The Trailside Museum, operated by Mass Audubon, sits at the base of Great Blue Hill. It's a small natural history museum with live native wildlife — owls, hawks, snakes, turtles, and a river otter. At $6 for adults and $4 for kids, it's an inexpensive add-on that works well before or after a hike. The museum also has educational programs and guided nature walks for families.

Getting there: drive from Boston via Route 93 South to Exit 3 (Houghton's Pond) or Exit 2B (Great Blue Hill). The Red Line to Ashmont and then the Mattapan trolley gets you close but not all the way. This is one of the rare Boston-area attractions where driving is genuinely easier than transit.
