After leaving Portland, we headed back east and stopped at Multnomah Falls. We accessed the falls via the historic highway, the parking area was jammed pack and it took a couple turns to find a spot. There is a larger lot along the interstate that looked to be easier to find a spot to park in.
We took a different (longer route) home from Vancouver and stopped off in Portland for a day. I had previously only driven through on my way to the coast a few years back, and am definitely hoping to be back soon.
