Beautiful hike. Crowded. Make sure you bring water as there is no where to fill up. Not even visitor center. No restrooms. Just overstuff porta potties. Come early. Parking difficult. We got here at 310 pm and found some. But there’s a lot of people. We waiting in line to get into park 1 hour! They need a better system!

Holy mountain views, Batman! That's all there really is to say about this famous photo spot. From here you get great views down into Paradise Valley, Mount St. Helens, Mount Adams and, on very clear days, Mount Hood.

This 19.1-acre park is a wide, grassy open space with plenty of pathways for a great run. There is a big hill on the grounds that is popular for flying kites, a playground, a sundial, and a gorgeous view of Seattle. The park gets its name due to the ruins of a former coal gasification plant, preserved behind a fenced area.
