Took Old Si trail again for some burn.
Did this one a little backwards - took the SECOND turn up Boulder trail, which is much steeper. Legs were burning before we even hit the Old Si trail.
Awesome steep hike - much harder than the main trail, and almost NOBODY on it.
Definitely needed the microSpikes... almost zero traction without them. We passed so many ill-prepared casual hikers once we hit the top.
The mountain jays were especially friendly at the peak. Great run down in the snow.
