Excellent news! The USFS recently approved approximately 10 miles of new mountain biking trails that connect Sunriver (near the Cardinal Bridge by Sunriver Lodge) with the Wanoga and Cascade Lakes Welcome Station trail networks. This occurs in conjunction with the Forest Service's intention to minimize human disturbance in the core habitat of the Ryan Ranch Key Elk Area.
Per the USFS Decision Memo shown below:
The purpose of this project is to increase areas of undisturbed core elk habitat while also providing recreation opportunities.
Trail construction will be a joint effort between COTA and the Sunriver community, with trail build events to be posted on Meetup (find COTA's Meetup page here).
Trail flagging will begin this spring, with most if not all mountain bike trails completed this fall. The majority of trails will be machine built with hand finishing, with a few sections contracted out to professional trail builders with appropriate larger scale equipment.
