Plan for Fun


Then and Now:

Since the 1920's, visitors have traveled to Newhalem, Washington to surround themselves with the rugged beauty of the North Cascades. In 1918, Seattle City Light began construction on three monumental dams over a 50-year time span to provide hydroelectric power for the city of Seattle.

Top Things to See and Do in Newhalem:

  1. Play! Ring the big brass bell on Engine Old Number 6.
  2. Eat! Try a FREE sample of homemade fudge at the historic Skagit General Store.
  3. Hike! Enjoy nearby family-friendly hiking trails.
  4. Explore! Cross the pedestrian suspension bridge over the Skagit River to view Gorge Powerhouse and stunning Ladder Creek Falls.

It's Easy to Get Here, it's Harder to Leave.
