Elm Creek Chalet bathrooms & water open
Sign on the door says open from 5:00 am - 10:00 pm. No bike racks outside the door, and no trash/recycle containers at the door. But, there is a large trash bin near the small shop next door to the Chalet if you need to dispose of anything.
Needless to say, lots of shade riding around Elm Creek! Also, wasn't too busy, especially for a Saturday, but I was there in the afternoon, so I don't know how busy at other times and days.
