We will leave the Little Si trail head at 8:00. Note time change.  

The route is Little Si TH, upper Boulder Garden loop, Old Si trail, Summit (weather dictates were we stop), back to Boulder Garden loop, finish the loop to the lower trail, and back to TH.  

This will be a steady pace with small breaks at trail junctions.  The goal is 2 hours to the top.  The pack may string out and that's okay but if you think you will need more than 2.5 hours, this hike may not be for you.   Everyone is welcome but I am helping Scramble and Basic students get in shape for their class.  

My number: 425-281-9635

Micro-spikes or equivalent mandatory as we expect compact snow and ice on the trail.

This is a dog friendly hike and my German Shepherd will be going (she needs to condition too).   Let me know if you have an aversion to dogs and I will make sure she respects your space.  Other well behaved dogs are welcome if they are strong on voice commands.

We usually linger in the parking lot after the hike for refreshments.  Bring a chair and a sandwich if you are inclined.
