Williamson County Indoor Sports Complex

Perhaps not the best pool in the world, but the best pool in my world. Good price, convenient hours, never that crowded. The rest of the facility seems great too.

I predominantly use the workout room here, and I love it! When I took a friend from Connecticut here, she couldn’t stop raving about the low cost and friendly people. Williamson County residents pay $ 3 per visit, but you can cut it down to $ 2 if you use a reloadable card and buy multiple visits at once. According to the website, nonresidents pay $ 6 per visit, but I’ve always just swiped my card twice if I have a guest with me.
Over the years the gym has added and rearranged cardio machines, especially treadmills. At the busiest times (7−9am, 4−6pm most weekdays) it can be tough to find one, but I’ve never had to wait more than 10 minutes or so. There’s a large selection of resistance machines and as many benches and free weights as you’re likely to find in a much more expensive gym.
The locker rooms are always clean. There are also additional bathrooms separate from the locker rooms, so if you’d rather not walk by a bunch of people changing, you don’t have to. The Olympic indoor pool is often in use for swim team practices and meets, but there’s a smaller pool off to the side (not a kiddie pool) that can be used for swimming laps too. I can’t speak for the indoor tennis courts, but I see people using them regularly.
Aside from the cost (exceptionally low for a gym this nice), the best part about this place is the atmosphere. I’ve been to plenty of gyms where the staff and/​or the other patrons are intimidating and unfriendly, especially to newcomers or people who don’t know how to use the equipment. Here, both the staff and the patrons are welcoming and friendly. This probably says something about the demographics of Williamson County, but teenagers and seniors seem to be much better represented here than in a typical gym. The result is a low-​pressure but very well-​kept environment.
The complex is tucked away in a wooded area right next to I-​65, so it’s easy to get to. If you’re a WilCo resident, definitely go; if you’re just visiting (or even in Nashville), it’s still not a bad choice.

This is a really nice facility! The swimming pool is huge, full Olympic sized (not Junior), and there are changing rooms, locker rooms with full showers, and a cool, centrifugal swimsuit spinner/​dryer.
The workout room has lots of treadmills, bikes, and ellipticals. There are also indoor tennis courts. There is a large parking area outside.
