“A steep, well-maintained trail takes you atop Mt. Si with outrageous views of Puget Sound.”— Benjamin Pontecorvo
Once out of the forest, there are many outcroppings to enjoy your lunch and some views. Most people will stop here- but the more adventurous can continue uphill and right on a stony path to the Haystack, Mt. Si's true summit. This extra 150 ft of scrambling is class 3/4 and is well worth is as the views to the North are revealed.
On your way down please do not cut trails. What saves you 30 seconds can cause decades of damage. Also you'll need a discovery pass to park at the lot. Have fun!
