Pretty -- don't be deceived by what looks like a trail on the far side of the falls though, it's not a real trail.

There is a small bit of gravel road up to the 1,614-foot Cougar Mountain. Although it is gravel, the road is generally well-maintained, but might be a little unpleasant on super, super skinny tires. This is one of the Issaquah Alps and a must-climb if in the area. You get great views from the summit.

Keep an eye out for the signs on the trees for the criss-crossing trails.

When navigating to the peak, some of the downed trees and vegetation can make it a bit confusing. There's white spray painted arrows on the ground at the most confusing spots, so keep an eye out for those!

Cougar Mountain Park spans nearly 3,000 acres, featuring over thirty-five miles of fantastic trails winding through second-growth forests, streams, wetlands, cliffs, and historical mining caves. There are breathtaking views throughout the park of the Cascade Mountains, Lake Sammamish, Bellevue and Seattle, along with other more secluded areas, which are ideal for spending time surrounded by nature away from the fast pace of the city. Most trails are mainly for hikers; however, some allow horseback riding, so keep an eye out for equestrians as you explore this beautiful area.

About 0.24 mile below the summit of Mount Si, this viewpoint on the Mt. Si Trail offers sweeping views of the Snoqualmie Valley through the trees. There are some boulders in the way of the view, but some will scramble around to see the view. Be careful, as veering off trail can be unsafe. The best views are close, at the summit!

The scramble up and down the final pitch is exposed and dangerous. Be careful, go slow and follow the “three points of contact” rule.

To reach the top of Mount Sai, you have to climb a steep rock wall. You need to be very careful when coming down as it is somewhat dangerous.
