Swimming Lakes You Need to Discover - West of Boston

1. Walden Pond—Concord

Since it’s a favorite spot for summer swimming, we have to start with Walden Pond. Walden’s waters are super clean and warm, plus there are lifeguards and roped-off swimming areas for smaller kids. A bathhouse with restrooms and changing areas is easily accessible near the main beach. Daily parking fees of $8 for Massachusetts vehicles and $30 for out-of-state cars apply.

2. Cochituate Lake—Natick, Wayland

People flock to the three sections of Lake Cochituate—north, middle, and south—for boating, kayaking, canoeing, windsurfing, fishing, and, of course, swimming. There are plenty of places to picnic, and nearby trails are perfect for stretching your legs. When swimming in areas managed by Cochituate State Park, daily parking fees are $8 for Massachusetts vehicles and $30 for out-of-state cars. The Wayland Town Beach also allows out-of-towners to visit and swim with a day pass.

3. Hopkinton Reservoir, Hopkinton State Park—Hopkinton

Hopkinton may be best known for being the start of the Boston Marathon, but it’s also home to the terrific Hopkinton State Park.

The state park also has ample spots for picnicking and trails for exploring. Daily parking fees of $8 for Massachusetts vehicles and $30 for out-of-state cars apply.

Only Newton residents can buy summer membership passes, but non-residents can purchase a day pass for $15 per person.

6. Morses Pond—Wellesley 

Morses Pond is a bit of a hidden gem in the local freshwater swimming scene. But it’s one that’s well worth adding to the list of places to head when the temperature rises.

There are also canoes, kayaks, and paddle-boards for rent if you're feeling adventurous. Non-residents can purchase season passes; $190 for adults and $90 for children. Daily passes are currently only available to residents for $5. 

7. Arlington Reservoir—Arlington

The Arlington Reservoir is a great place to take kids for a freshwater dip. It has a swimming area with a beach that’s monitored by lifeguards, a concession stand, a bathhouse, a playground, and even summer concerts. Buy a season pass if you plan to come often, or a day pass for a one-time visit. Those who are feeling adventurous can ride bikes to the reservoir, which is very close to the Minuteman Bikeway. As a bonus, Arlington Recreation hosts free summer concerts every other Thursday.

8. Breezy Picnic Grounds Waterslides—Douglas

Summer is a breeze here with three 300ft waterslides (plus a kiddie slide for little ones under 42"), a swimming hole, picnics in the park, a concession stand, lifeguards, and free parking. This place is the definition of how to spend a lazy summer day, basking in the summer warmth and glow.
