This ride starts from the Discovery Center at the west end of The Dalles. Ride historic highway 30 through Rowena and then up a long climb to Rowena Crest. Continue on highway 30, past Memaloose Trailhead and through large orchards, before descending into Mosier. Ride through Mosier and turn right on Rock Creek Rd. Continue up a short hill to the Mark Hatfield Trail. More climbing to the tunnels, then a short drop. A little more climbing, then gradual descent to the main trailhead/visitor's center (which was closed due to COVID). Decided to continue on highway 30 down the hill to Hood River. Return same way. Did this ride on an older triple-ring Klein bike. Does not have a Garmin computer. However, the computer it does have registered 2911 ft climbing.
