Description

Location: North Cascades, WA

Date: Sunday, June 22, 2025

Participants: priority given to BMC 2025 grads – max 12

This is a great early-season fitness and scrambling challenge. Twin Sisters North offers outstanding ridge scrambling on excellent rock with route-finding and optional spicier sections. It’s a big, rewarding day that blends mountain biking, hiking, and fun Class 3-4 scrambling. Once on the ridge, we’ll be treated to sweeping views of Puget Sound and Mount Baker from the summit. The rock here is a rare type of dunite—solid and grippy rock that is unique to Washington. Expect an 10-14 hour car-to-car day.

Trip Breakdown:

  • Drive: ~2hrs from Vancouver
  • Bike: 10km with 600+m elevation gain on well maintained gravel road (~2hrs)
  • Hike & Scramble: 2km + 500m vertical (~5-7hrs round trip)
  • Bike Descent: ~20-40min depending on pace

Important Notes:

  • This trip crosses the U.S. border, so make sure to have your valid passport or required travel documents with you
  • No water sources past the bike drop—you’ll need to carry all the water you need for the hike and scramble.
  • Bring a bike lock as we will stash and lock our bikes in the bushes before the hike.
  • Glissade descent might be avoided if participants feel uncomfortable with the steepness, and instead retrace the ridge on our return.
