Looking for abandoned, haunted buildings to explore in Central oregon.? -

My girlfriends and I want to do a girls trip and all of us are fascinated by abandoned building and exploring them. Would love to spend the night in an asylum or something like but the only ones I can find are on East coast. We could drive to Washington or California as well. Tours would be great but really hoping for something like the asylum in WV where they lock you in around 9 and let you out at 5am and you can explore on your own. Thanks for the help.
