It's called Cascades Camp and it is in Yelm. They do have a website. Here's the main website:

And here's the link to some of the fun activities that they have available:

Since my son is 10, he will ride along with a teenager who will drive the Kubota. And, his paintball activity is just shooting at targets. Kids have to be 13 to drive the Kubota or play a real game of paintball. As soon as he's 100 lbs. he'd be able to do the zip line, too. But, sad for him, that may be a few years... the kid is skinny, skinny, skinny. He just grows up and never out.
ETA... he's staying in Brightwood Station (a railroad box car), which is perfect for him. He LOVES trains!
