We started a few miles southeast of Estacada in the parking lot at the PGE Powerstation off of Faraday Road. A 5 mile paved pedestrian/bike trail starts there and follows the North Fork Reservoir of the Clackamas River to Promontory Park where it joins Hwy 226 again. It’s a gradual incline for dozens of miles, and after a couple of hours, we found ourselves beyond The Narrows, a gorgeous spot to swim.
Cycling along this route prompted us to join a day-long Blue Sky Rafting trip later in August along this same stretch. We highly recommend their trips.
Returning to the car was an easy coast back down the road. Cyclists do need to watch out for the large divots in road pavement due to falling rock from the cliffs above.
