Peterson Ridge View Point

With plenty of terrain to explore, avoiding doubletrack in this area is easy enough to do and well worth the effort.

Although the terrain is too easy for this to be a destination ride, this is a favorite ride for those staying in the Sisters area, and worth checking out.

CW directions are given in the guide below, but the west side terrain is less technical, making a CCW loop somewhat easier.

This is a shared use trail system, with equestrians on the doubletrack and on some of the singletrack.

Plenty of ways to bail out to FR16 and FR4606, if needed.

Rather than simply riding the loop, use the many connectors to create a serpentine ride.

Directions: From Sisters, go south on Elm St then turn left on Tyee, TH is on your right. View Larger Map. No Map?.

Peterson Ridge Area Topo Map

  • TH: Bear to the left at the fork. Pass intersections #6 at.9mi; #8 at 1.1mi and #14 at 1.8mi, over relatively flat terrain, crossing several doubletracks and drainage ditches. Cross FR4606 at 2.7mi.
  • 3mi: From the #16 (3mi) intersection, ascend a butte, passing #18 intersection at 3.6mi and cresting the butte at 4mi. Descend and cross a doubletrack, then ascend (crossing two additional doubletracks) to #20 intersection at 4.7mi, just prior to the Plainview ditch crossing.
  • 4.8mi: Climbing steadily, cross two doubletracks before reaching the #22 intersection at 6mi, then cross two doubletracks before reaching the #26 intersection at 7.5mi. Cross FR665 at 8.7mi and reach the ride summit at the #33 intersection (9mi).
  • 9.7mi: After a short but sharp descent, the Peak View point marks the mid-ride point. Climb alongside some doubletrack to the next summit at 10.1mi then descend to the #25 intersection at 11.3mi.
  • 11.9mi: Pass the #29 intersection then cross FR1608 at a 4-way doubletrack intersection. Stay on the singletrack and reach the Peterson Ridge Viewpoint, just past the #21 intersection at 12.1mi. Cross the Plainview ditch then pass the #19 intersection at 12.8mi. Cross FR900 at 13.1mi as the trail levels off somewhat, then resume the descent, passing the #17 intersection at 14mi, then reaching the Squaw Creek #15 intersection just prior to the 'big' bridge (14.8mi).
  • 15.6mi: Pass the Eagle Rock intersection (maybe climb to the other side or loop around), cross FR4606, then pass the #11 intersection. Back to the flat portion of the ride, pass the #7 intersection at 16mi and the #5 intersection at 16.5mi, on the way back to the TH.
