Just wrote a post about Olive Lake about 10km up the pass from there. Never knew it was called Sinclair Pass, guess we just take photos and don't read the signs.
The Juniper trail through there gets you some really good views of the area (I'll post about it one day). We didn't stop to take a dip in the Radium Springs and opted for the Fairmont Springs instead.
How about you?
Truth be told, had to do some quick research on that. We did hit the springs twice, it was good, but I thought the water could have a bit hotter actually. How was Fairmont?
Fairmont is big, there's one big hot tub which is a tolerable temperature and a couple larger swimming pools that are not hot. The views are better.
