In October you will/could/should encounter the beginning of the rainy season on the west side of tne Cascades, so, in my humble opinion (unless you like rain) I recommend staying east and coming to the wet side when required.
There are 2 state parks south of Seattle that are fairly easy to get to from downtown Seattle. I recommend using old highway 99 or 1st avenue south to avoid traffic on I-5. There will be traffic, it is narrower, but you will be moving! The 2 state parks are Dash Point State Park anf Saltwater State Park.
Plenty of hiking trails and on the beach of Puget Sound, both parks are heavily treed, and are, it seems, within your required 1 to 2 hiurs from Seattle. http://www.parks.state.wa.us
Be safe.

We're having to change our Arizona October vacation to Washington state. Very open to suggestions as to where to go, with an itinerary driven by the following constraints:
Week 1, depart the Salt Lake City area Saturday morning, destination???? Open to suggestions for a week and a half. The Wed of the second week we need to be close enough to Seattle that I can drop the wife off mid day for a conference downtown, and I'll pick her up mid day Friday. The dogs and I will be camping solo for those two nights, preferably camped maybe an hour or two away to the southwest being as how we'll have leave Saturday morning to be back in Utah by Sunday evening so we can return to work Monday morning. I'd like to try and keep that part of the trips driving distances as reasonable as practical hence being southwest of Seattle at that time.
I'm very open to suggestions, especially regarding what to see and where to go given the time of year.
