If you like ghost towns and abandoned places, this is rad. It's $8 to get in per person/vehicle. It's a protected state landmark, so there are rangers that live in some of the outbuildings to watch the place. It's full of great photo ops and you can walk as long/far as you want to explore every single building if you like. I got some great photos, and it's very peaceful out there. Definitely worth the detour, but be aware the gravel road to the park is a long 2 miles of rumbling at 15mph. Awesome!!
It's easy to find, free to visit and park, and is part of an adorable Frontier Town that has old buildings to explore and take photos of. It's a great stop to stretch your legs, enjoy an open skyline, and grab a snack at the picnic area.
