My husband and I had tried to visit this observation desk last summer & it was always closed. This summer Linebergers restaurant is gone, but the observation deck was OPEN. This observation deck is located at the back of Ole Smoky Moonshine Holler. At the back of the holler you will see an elevator & stairs. IF you go up to the 3rd level, you will be on the observation deck.
From the observation deck you can walk around and get a 360 degree view. From the back you can see parts of River Rd and the Sky LIft. From the sides you basically get views of business rooftops. But, the best view is probably seen from the front facing the parkway. From here you get a view of the Space Needle, Arcadia, the Park Vista, Star Cars, Blaine's and Moonshine Holler down below. When we were there, there was a live band performing in Moonshine Holler. So it was kind of neat to watch them perform from above.
Overall, this observation deck is OK. You do get a nice view of the Space Needle & Sky Lift from here. Plus I liked the overhead view of Moonshine Holler. It doesn't cost anything, so it doesn't hurt to take a peek.
