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?
