Before the summer heat leaves us this fall, take a dip in one of these five indoor pools around town.
Switch up your workout routine and swim some circuits in Boston’s largest heated lap pool. The retractable roof makes the pool a viable destination for all seasons. 39 Dalton St., 617-236-2000
Plunge into the refreshing waters of the Hyatt’s 52-foot saline indoor swimming pool. The space is adjacent to the hotel’s StayFit Gym complex, making it easy to follow your swim with a trip to the sauna and the gym’s chilled towel service. One Avenue de Lafayette, 617-912-1234
The Royal Sonesta’s atrium-style pool is salt-based and completely chlorine-free. The pool has three lap lanes perfect for getting in a workout, along with a large resting area for those just looking to take a dip. In the warmer months, you can relax and lay out on the pool’s seasonal sundeck. 40 Edwin Land Blvd., Cambridge, 617-806-4200
The Four Seasons’ indoor pool is surrounded by floor-to-ceiling windows, which provide a breathtaking view of the Public Garden and Beacon Hill from eight floors up.
