Driving out to Three Pools is pretty easy, its a nice little day trip outside of the Portland area, about a 2 hour drive. Easy to get directions to with a quick Google search. Unfortunately at times it can get pretty crowded but that should be expected with arguably the best swimming hole in the state of Oregon. There is a 16.5 cliff to jump off that is super fun, I climbed up and jumped off a few times but I love that sort of thing, if youre not as into that then theres a few smaller pools to lounge out and soak up some sun. I had a great experience here and cant wait to do it again. If you are visiting Portland in the summer time I would suggest to make this a day trip like I did.
I heard they are trying to start turning cars away after the 90 car parking spot is filled, try to make it as early as possible!
