We found one in Lake Louise...the Sunny Tube Park at the Lake Louise Ski Resort. This tubing area was smaller with only two runs but the magic carpet was working and the price was right! I was concerned that we would be the oldest folks at the tube park or at the very least, the only ones without little children. Surprisingly everyone on the hill was our age. Many of them were non-skiers who opted to tube while the rest of the family hit the slopes with their skis or snowboards.
After several hours at Lake Louise, we returned to Banff and checked out Banff Upper Hot Springs. These mineral rich pools are naturally heated to 104 degrees. I was hoping that the atmosphere would be more grotto-like but instead, it was a large tiled swimming pool. But no matter....the water felt great and the sensation of being in that hot water while the steam rises and the snow flurries down was something entirely new to us. I highly recommend it! Much better than a hot tub!
