The ride up by bike is tough, of the 2400ft of climb, the first 2200ft of it is in in apx 3 mi. Trekking gears on a tour bike are do-able, but recomend a Mt. Bike for this climb.
On a clear evening You can see Mt Baker to the east, With Lummi Isl in the foreground.
Hike, Bike or drive, It truely is spectacular.
