This is a very nice pool facility, with 3 fast water slides, wave pool, diving well, lap pool & large hot tub (the latter for adults only). For the first 30 minutes after it opens each day it's not too crowded and is wonderful. By an hour after opening time, it's standing-room-only in the wave pool and the line for the water slides can by 10 min long. The noise level at this indoor facility can be truly astounding -- if I plan to sit & read while the kids swim, I bring & use earplugs.
The water temp in the lap pool is nice & cool for swimming laps, in the other pools it's warm for wading. I haven't tried the hot tub.
There's a decent sand volleyball court outside by the patio.
This is one of the best pool facilities you'll find in Portland metro. If you are from Denver/Boulder metro or another area where every other town has a community rec center, then you might not be impressed by anything but the crowds here. But in the Portland area, where funding is short for public recreation facilities, this is a must-go destination.
