Welcome to the Mt. Si Motel in North Bend, Washington which you probably recognize as the Blue Diamond Motel in Twin Peaks: Fire Walk With Me.
This filming location was used when Leland meets his prostitute Teresa Banks and some of her friends, which includes his daughter Laura! He flees in terror before he is seen and gets the hell out of dodge. Today the motel has seen better days. In all honesty it’s a pretty rough place and I’m not so sure I’d feel comfortable staying there, but in my visits over the years to the motel the staff is very nice and accommodating, willing to show you the very room where Laura and Ronnette get ready to party. What looks to be a huge stain of either grease or perhaps a fire on the wall was claimed to have been applied by Lynch himself for the scene.
The motel is right down the road from the Double R Diner at 43200 SE North Bend Way, so drop on by and hop around the parking lot.
