Southeast of Hood River, the Dog River Trail (#675 / 6.2 mi. / 2100) climbs (steep at times) from Hwy 35 up to Surveyors Ridge. Along the way you will have many chances to gaze at the glacier carved northeast side of Mt. Hood. The trail is smooth and fast in some sections, rocky and technical in others making for a fun well rounded mountain bike ride. This mountain bike ride can be done as an out-and-back, or it can be looped up with Hwy 35 and FS 44. For the energitic, this mountain bike ride can be looped up with the Surveyors Ridge Trail (#688) for 18 miles of single track (6 up & 12 down, plus mileage on Hwy 35 if your not using the two car shuttle system).
To reach the mountain biking trailhead from Hood River, head south on SR35 for approximately 20 miles. Just south of milepost 78, there is a small parking lot on the left (east) side of the road.
If you are doing this as a point-to-point using the two car shuttle system, then continue heading up Highway 35 for about another 7 miles. Turn left on FS Road 44 and drive for approximately 3 miles until you reach road 620. Park here.
Overall, Dog River Trail is the 6th most popular mountain bike trail of all 55 mountain biking in Oregon.
