Love this little-known hike. Right next to Little Si & Big Si, but this is WAY less crowded, and jncludes a lot of cool little scrambles, and a TON of waterfalls. The only problem with this place is the lack of parking. Plan to get there early, or you have to park a half-mile down the road and walk back. There are spots for around 10 cars at the trailhead.
In the spring, the streams are running hard, and the entire second half of this trail follow a continual waterfall. Lots of switchbacks, and not toi steep before the main waterfall.
Don't stop there! Most people turn around here after lunch... but if you like to scramble - keep going up past the falls to the right. There is a new boot trail (hard to see), that takes you up to the ledge - great scramble. We did turn around at the falls on this hike, but look for one of our previous hikes here for the GPS track to the ledge.
