This trail provides easy entrance or exit on the north-side of Galbraith. Karma is low commitment singletrack that meanders through a clearcut. The trail intersects with Lower Bob's just before ending on the 1020 - Pipeline Connector
Continue onto the Karma Spur to Alvarado Drive. If you parked at the Birch Street Trailhead, the most direct route back to your car is: right onto Edwards St. (includes about 20 ft of trail), left onto Roland Street, right onto Whatcom Street, left onto Raymond Street, right onto Riley Street, and then right onto Birch Street.
If for some reason you end up on Lakeway Drive, follow it to the east until it connects with Birch Street.
