I've swum in many pools across the world, and this has got to be one of the best. Super friendly staff, great lane availability, lots of open hours. You can choose between lap swimming in a warm pool (diving well) or the cooler competition pool (around 80ºF). It gets a bit busy right after work but lunch time and evenings are fine. Towel rental is $1 for drop-ins and you can borrow a lock. The day pass to the pool also gets you into the main IU gym.
