Thanks for everyone's suggestions. We ended up traveling I-90 to exit 151 and then going north through Quincy and then west on Hwy 2 through Wenatchee and Leavenworth. Hwy 2 is predominantly a two lane road and the grade going up and back down Stephen's Pass was not bad. The drive was beautiful and worth taking a little extra time.
All the posts talking about going through Seattle lead me to wonder if I got the O.P. wrong...I thought the final destination was the Park, not the Puget Sound corridor.
Are you going through, or turning around and heading back east after the Park? If the latter, what part of the Park are you headed for?
After leaving North Cascades NP, we will be headed south to Oregon. Thanks for the suggestions!
We are currently in the Spokane WA area and will be traveling to North Cascades NP at the end of the week. Which route has the easiest mountain grades and best driving? I-90? Hwy 2? or Hwy 20?
Thanks for your help!!
We were there last July.
We recommend the Western Brook boat pond tour in Gros Morne National Park. It was absolutely beautiful.
Another interesting museum was the cable station at Heart's Content.
Also, be sure to watch out for moose when you are driving.
