I'm planning a cross country bike trip and Ellensburg is about the right spot for ending day 2. Is there a location where camping is available for one night that would be inexpensive?

No tent camping here. I would try the KOA....much better facilities.

If you go to irene and go to the forrest and pitch a tent they give u like 2 or 3 days before kicking you out. Unless you get caught before that time. Then they prolly give u an hour or so to bug out. Its a risk but ay its what makes life fun

I agree with ward. Your best bet is the KOA, but other than that this spot is good to bike by and check out the scenery
