It appears due to my sons high school commitments we may have to travel early June instead of mid July so...... I assume any high country hiking will be out! I wanted to hit North Cascades, Olympuc national park and Mt.Rainier. What areas usually are open mid June? I know it depends on snow ect but what can the experts tell me? I thought Noth Cascade would be out so maybe we will head to the Columbia river gorge area and the coast. We have 12-14 days to travel.
