Although there are plenty of beaches near Boston for families to spend the day swimming, the ocean is often cold and rough, which can cause more stress than relaxation! If you prefer swimming in warmer, calmer water, you’re in luck — there are a variety of lakes and ponds nearby for a day of splashing in freshwater. Here are 10 of our favorite swimming holes in the Boston area!
Walden Pond :: Concord
Walden Pond is the famous setting of Henry David Thoreau’s “Walden.” Enjoy swimming in Walden’s clean, warm water, or stroll along the trails through Walden Woods. Available amenities include restrooms, a boat ramp, picnic areas, and a visitor center. Daily parking fees are $8 for Massachusetts vehicles — we recommend you check the Walden Pond State Reservation X account before you go to ensure the parking lots have not reached capacity. Note that water levels are very high this year, so beach space is limited!
Mystic Lakes :: Medford
Medford’s Mystic Lakes are a true hidden gem when it comes to swimming holes a stone’s throw from Boston! Shannon Beach has a lifeguard on duty and wooded trails to explore, plus a brand new building for restrooms and showers. You can bring your non-motorized boat (power boats with no wake are allowed on Lower Mystic Lake), paddleboards, and other water toys to play here. There are also picnic areas with grills. Free parking is available on site.
Lake Cochituate :: Natick
Three connected lakes make up Cochituate State Park. All three lakes are accessible by boat, plus waterskiing and tubing are allowed on South Lake. On Lake Cochituate, you can enjoy swimming, non-motorized boating, canoeing, kayaking, fishing, and hiking in the surrounding trails. There are boat ramps, picnic areas with grills, and restrooms. Parking is $8 for Massachusetts residents.
Houghton’s Pond :: Milton
Located in Blue Hills Reservation, Houghton’s Pond is a popular swimming spot. This 24-acre pond and recreation area is perfect for swimming, fishing, hiking, biking, and horseback riding. With a first-aid station and lifeguards on duty from Memorial Day until Labor Day, it’s one of the safer swimming holes. There’s plenty to keep busy families occupied, including picnic areas, ball fields, a boardwalk, a concession stand, and a playground. There are also restrooms and showers. Free parking is available on site.
Pearce Lake at Breakheart Reservation :: Saugus/Wakefield
Breakheart includes two lakes and a forest. Pearce Lake is supervised by a lifeguard and is closer to the Wakefield entrance. Besides swimming, there’s hiking, biking, fishing, horseback riding, educational programs, picnic areas with grills, a first-aid station, restrooms, and a playground. It’s also conveniently located right next to a Target, so you can stop in on the way if you forget your sunscreen. Free parking is available on site.
Crystal Lake :: Newton
Crystal Lake and its public beach is a popular spot for visitors to swim, fish, bird watch, hike, and boat. It is surrounded mainly by private homes, so taking the T is your best option to avoid searching for street parking (it’s on the Green Line). Crystal Lake offers a long dock to jump off and a floating dock to swim out to. No outside chairs or umbrellas are allowed on the dock or beach, so bring your towel and sand toys and leave the rest at home. Picnic tables and restrooms are available. Daily passes are $8 for residents and $15 for non-residents.
Arlington Reservoir :: Arlington
The manmade Reservoir Beach was built in 1870 and has long been a popular swimming hole that includes a filtered/chlorinated swimming area. It was renovated recently with a new bathhouse, snack bar, picnic pavilion (no grilling allowed), water play area, playground, sport court, lawn, walking path, and parking lot. You can even book the picnic pavilion for parties. Lifeguards supervise the beach, and some non-inflatable water toys are allowed. Daily passes are $10 for adults and $5 for children/seniors.
Morses Pond :: Wellesley
Morses Pond covers about 100 acres of land where visitors can enjoy swimming, boating, hiking, and fishing. It includes a playground, picnic area, and restrooms. Lifeguards monitor a roped-off swimming area, and an ice-cream truck visits regularly. You can also rent canoes, kayaks, and paddleboards. Non-residents can purchase season passes for $190 for adults and $90 for children. Daily passes are $5 and are only available to residents.
Hopkinton Reservoir :: Hopkinton
Although Hopkinton is best known as the starting point of the Boston Marathon, it’s also the location of beautiful Hopkinton State Park. The park consists of two seasonal swimming beaches that are monitored by lifeguards, and there are restrooms on site. This state park also has spots for fishing, paddling (rentals available), picnicking, and hiking. Parking is $8 for Massachusetts residents.
College Pond at Myles Standish State Forest :: Plymouth
If you’re willing to drive a bit, College Pond in Myles Standish State Forest is one of our favorite swimming holes farther out from Boston. It features a sandy beach, hiking trails, biking, fishing, kayaking, canoeing, and even camping if you’re feeling adventurous. The facilities include a boat ramp, picnic areas with grills, restrooms, and showers. You could make a day of it or spend the night to explore Plymouth the next day — try the Plimoth Patuxet Museums and the local shops and restaurants. Parking is $8 per day for Massachusetts residents.
Walden Pond is closed for swimming for the summer.
The pond overflowed and there is bacteria contamination.
Hey Jenna! Walden is actually open for swimming this summer (2024). My family has been there a few times — the lifeguards are out, and the swimming is lovely! You can look up DCR closures online, where they make regular updates about which of their locations are closed due to bacteria.
