My wife and I are thinking of heading up to NW Washington mid July and I was wondering if anybody had some suggestions on which area(s) are better this time of year or even if going in July is a good time? Would it be better to concentrate on the Olympic National Park and coast area or the Cascades, Ross Lake, Mt Baker, Wenatchee area? We'll be zipping around by car and interested in up to half day hikes to areas (we're young and reasonably fit )

We'll be in the area 2 days for sure but I'm trying to figure out if its worth adding 5 days onto the trip in July or if we should just come back a better time of year and what the best time of year is.
