Narrow and in the trees. Lots of ferns and miscellanous foliage around the trails. Forget about seeing the sun. Probably 6 or so different routes through the forest, which is an undeveloped county-owned section of land between Issaquah and Redmond. Has some genuinely difficult trails, and a few steep and loose climbs.
How to get there:
Get off I90 at the Front St. Exit in Issaquah, get going north up the plateau on Issaquah Fall City road. Continue following the road, it will turn right at a T junction. Turn left on 32nd Street. Take a right on Beaver Lake Drive. A couple miles down the road on you will see a small gravel parking area and a not very well marked trailhead. Go down the trail, at the first trail crossing there will be a map of the trail system on a tree. If these lousy directions confuse you, refer to a map of the Eastside, Section 36 should be on it.
More or less just a trail system for people in the neighborhood.
