My wife and I had always planned to visit locations that might not necessarily be standard tourist locations. When we saw the Tillamook Cheese factory, we knew we had to stop -- plus, we really love cheese.
There are numerous static displays of cheese-related items in the lobby heading toward the factory line itself. Life-sized ceramic cows look at you and demonstrate various types of milking apparatus. And, of course, there are samples of various types of cheese.
But, if you're a fan of seeing how things are actually made, you'll have to go upstairs to the observation deck. From there you can see the vats where cheese and ice cream are made (and an ice cream stand is open there during the summer), as well as the assembly line process taking cheese from large blocks down to individually wrapped packages.
It's impossible to go to the deli aisle without thinking of this trip.
