  • Very Strenuous

Steady gain with some very steep  parts.

This hike will be led at a CHS 1 pace so if you are not comfortable hiking at a slower pace, this may not be the hike for you. We will hike together. Please do not run ahead of the group. 

I will likely want to stop on the way back to Seattle for a meal.  This hike is a long drive from Seattle so please do not make any other plans as it will likely be a very long day.
