Inner Tube Water Polo open play is free for adults over 21 to try out a week before the league begins. We play 6v6 in the heated pool at San Jose Athletic Club on Sunday nights at 7pm. Enter on the 4t h Street side through the pool gate. Join us for this free event and if you like it, join us for the league starting 6/24. It WILL be a blast! It's the most fun sport you have never played!
