Glacier National Park

  • Seems to be awesome.
  • Rafting until mid july.
  • Some hikes here.
  • July/August seems to be the best time.
  • Expensive flights to Glacier Park International Airport, 10 hour drive from seattle.

Also:

The pros about coming in summer are that most of the trails are open, the flowers are blooming and the weather is nice (usually).July and August is our summer.
