Big, Big Red

Development Route / by Captain ‘O’ & Gravel Girl

Note: This is a Development Route, meaning that it is a work in progress and currently does not meet the Dirty Freehub 5 Star standard for great routes.

A longer version of Big Red that is easily accessible from Bend. We really like this route before Memorial Day and after Labor Day. During the summer, it has a “pinball wizard” feeling as you navigate through Sunriver during the height of tourist season.

We anticipate this becoming a 5 Star ride once COTA completes the new mountain biking trails just to the west of Sunriver. (Currently we have it listed as a Development Route.) We continue to work this route, making subtle but significant changes. We have ridden this route in its entirety.

    Great, eclectic ride. I had no real GPS issues other than me *assuming* I was going one way and the seeing “off course” on the Garmin. ?. One note I would add is there is no water until around mile 42 when you hit a Shell station in Sunriver. There is a liquor store near the corner of Lunar Dr. and Spring River Rd. At mile 37.4. Just make a left (instead of a right) and go about 100 yards and it is on the left. So pack plenty of liquids.

    Great route. Keep up the good work, folks.

    This was a super fun ride. Thank you! Navigation at 3.15 miles (just after the bridge above Benham Falls) can be a bit confusing (I encountered a couple of folks there who were riding in circles looking for the way). Take the dirt trail that heads south from the east end of the parking lot, not the trail closer to the river at the west end. Unlike DennisK, I enjoyed the path sections near Stage Stop Drive. It’s a fun way of seeing a neighborhood that you can’t do in a car.

      Thanks for the feedback, this really helps us make the routes better! We have added a couple of additional notes to the cue sheet and slightly re-mapped the section at mile 3.15 to make the routing more clear. There will be a few more changes to the route as COTA does additional work in the area. But … it keeps getting better. Thanks!!

    From DennisK:
    Here are a couple of comments. Add / Change when do the major update to the route after COTA finishes it’s work with the new trail system.

    * Between miles 14 and 15 and 32 and 33, I would just stay on Stage Stop Drive and skip the paved bike paths. They are very confusing.

    * At about mile 30.5, turn right onto Big River Drive and get back on S Century Drive at about 31.5 for a break from traffic.
