2.3 miles from Auburn Courthouse. Moderate-steep 5 miles round trip. MAP
Less steep than Cardiac but easier for man and beast, the bypass was created to offer an easier alternative to Cardiac. It also gets you down to the river at Oregon Bar but uses some roads to make it easier.
Directions: Same as Cardiac, but branches off behind gate #145 to drop riders and walkers down to the China Bar road where a L turn just past the falling down shed of core samples will take you down a rocky old road that comes out near a parking lot. From there you find the trail going out the back side of said lot that ties into Cardiac trail closer to the river and nearer those new switchbacks. You can also take the road labeled “Birdsell” down to Oregon Bar which is even easier than the parking lot way.
