Tom Sawyer Pool's competition-size splash factory hosts recreational dips and year-round swim lessons overseen by a cadre of capable lifeguards. With a 10-entry rec-swim pass at hand, swimmers can avoid the penny peltings at the local wishing well by instead taking refreshing plunges into the pool's heated waterways––ideal for revitalizing workouts or soothing staycations from the UV-slinging sun. Doggy paddlers stranded on the shallow end can opt for Tom Sawyer's intimate swimming lessons, which ably impart maritime savvy to pool dwellers of all skill sets. A package of eight 45-minute lessons helmed by Red Cross–certified instructors spans four weeks and guides students through a wave-riding array of front and backstrokes, aqueous safety guidelines, and whip-crack towel snaps. Tom Sawyer Pool is open year-round and guests can check the website for recreational swim times.
