Because of heavy snow, the North Cascades National Park is only open to through traffic on SR 20 between late April and late November. The Anacortes area is hilly, the roads are curvy, and there is a moderate amount of residential traffic. The 4-lane highway that heads east to the mainland is very busy. After crossing the Skagit River flats, the route starts a long, gradual climb to the Pacific crest of the Cascades. In most places either the roads are wide or the traffic is light. After Washington Pass, the route climbs and descends a pass almost daily until reaching eastern Washington. Once in Idaho the terrain flattens as you wind your way along the Pend Orielle River into Sandpoint.

2 bikers with 40 to 50 pounds on the bikes, coming from Jasper and going to Vancouver.
The guide was very useful in the towns and to get rid of heavy traffic, specially in the surroundings of Anacortes.
We must mention three modifications :
-near Winthrop, the camping "Pine Near" doesn't exist any more;
- there is a "Bicycle Barn Camp" 8 miles west of Winthrop.
- It is possible to put tent (free) in Diablo
Northern Tier Section 1
Joseph Duncan on 5/4/11
I purchased the first section of the Northern Tier route just to get an idea of the information provided and the level of detail before buying the entire set. I was very impressed on both counts. I won't begin the ride from Seattle to Connecticut until the first week of August, 2011, but I should be able to plan and ride the trip very nicely with these maps. I'll review the whole package once I complete the ride in early October.
