What other abandoned places in Washington should I visit?

The Snoqualmie Tunnel in Washington isn't the only abandoned place to visit. If you are drawn to things that are being overtaken by nature and are a bit on the creepier side, here is a couple for you. Nestled in the Mount Rainier area is the ghost town of Melmont. It's been long since abandoned but you can hike to it and see what remains. There are a few building foundations, the remnants of a bridge, and rotting cars covered in plants and moss. Govan, Washington is another ghost town that you can visit. The empty shells of buildings are quite eerie, including a schoolhouse and post office.

What hidden gems in Washington are worth checking out?

You may have never known that this tunnel trail existed, but now that you do, you might be wondering what other hidden places are hiding in Washington. For another unique hike to an unusual tunnel of sorts, visit the Blue Lake Rhino Cave near Coulee City, Washington. It's a cave that is rhino-shaped, hence the name, but the shape didn't come by coincidence. The tunnel was formed when a prehistoric ancestor of the modern rhino, called a Diceratherium, got caught in a lava flow. The lava cooled around the animal's body and turned into the rock that remains today. It's well worth the scenic hike to get to it.

What are the most unique places in Washington?

Abandoned and rhino-shaped tunnels are certainly unique, and there is more where that came from. If you enjoy unusual, sometimes downright bizarre places, this might interest you. There is a very strange, yet fascinating hill near Prosser, Washington. Known as the Gravity Hill, you can stop your car and put it in neutral, and then be amazed when you watch it roll uphill. Though some question it as being nothing more than an optical illusion, others have said they have checked the elevation and can see it is an actual incline. How does your car roll up it? Good question - experience it for yourself and try to figure it out!
