We say goodbye to Wallace, Sequim and the Olympic Peninsula, and go to Port Townsend, am astonishing pretty historic town. The ferry has got an engine failure, has to be repaired first and we are sent away for the moment. But then the midday ferry departures on time after successful test drive, and brings us to Whidbey Island. After getting advice we decided to take the most northern rout to Yellowstone National Park since this seems to be the most varied one. Hwy # 20 leads us on the island through a pretty piece of rain forest and over some rivers. Once passed the bridge to the mainland, we land in a densely populated area with heavy traffic that fortunately decreases beyond the coast. Soon we are crossing the Northern Cascades, a picturesque landscape that charms us with freshly snow-covered mountains, racing brooks, small waterfalls and green reservoirs. No parking lot where we stop to stretch our legs where we dont have to conduct conversations to satisfy curiosity. Despite the glorious sunshine, in the evening it soon gets chilly, it has only 3° C above zero. After leaving North Cascade National Park we enter a National Forest where dispersed camping is permitted with few restrictions. We find a trail head parking lot where overnight parking is not forbidden. Having the interagency annual pass America the Beautiful, user fee is dropped.
