Part of, and great access to, the extensive Tiger Mountain trail system. I have use this trailhead to reach the Tradition Plateau, Poo Poo Point, and West Tiger Summits 2 and 3. You can get to the trailhead via the Metro stop, or the Sound Transit bus from Seattle stops a few blocks away. There's also a decent amount of parking for when the wholly inadequate Poo Poo lot is full. Definitely one of the hidden treasures of the Issaquah Alps system.
I'm certain it must be beautiful, but was too crowded to even get there. Will attempt on another date.
