Cool yourself down on those hot summer afternoons at the Arnold swimming pool. Open seven days a week from June 1 to mid-August from 1–5 p.m. and 7–9 p.m. except on Saturdays. Adult swim time is at 5:00pm to 6:30pm on Monday, Wednesday and Friday. Our babies swim free in the baby pool. Don't forget to sign up the youngsters for public or private lessons.
