The Tualatin Mountain Forest, known to riders as the Rocky Point trail system, is an Oregon State University research forest. The area is approximately 3,100 acres and currently has a mixture of gravel roads and 40 miles of singletrack trails optimized for off-road cycling, but also open to walking.
Update (1/24/2026)
Forest road, flagging and culvert work is taking place through the south side of the trail system by Oregon State University. Please use caution and PLEASE YIELD to any OSU or forestry employees and vehicles you encounter. Harvest operations and forest health work is planned to begin in March 2026, and will result in intermittent trail closures. Exact trail closures and timing is TBD; NWTA is working with OSU to communicate known closures to NWTA members as information becomes available.
A note on projected harvest operations
OSU’s Tualatin Mountain Forest is a working forest. The OSU College of Forestry is dedicated to forest research and management (read more about their mission, vision and research forests as living laboratories here). Harvest units are designed with recreation and aesthetics in mind, along with promoting healthy ecosystems, habitat, and watersheds. Current harvest operations are slated to consist of variable retention harvesting, where islands of 0.15 to 0.40 acres are left throughout a harvest area. Being mindful of recreation and trail restoration as a component of the forest, the islands are often anchored to notable trail features such as switchbacks. The islands are also often anchored to key habitat needs, serving as locations for forest organisms and species during disturbance events and creating healthy, more natural post-harvest regeneration opportunities. It is this type of harvest activity that is currently anticipated on the south side of the Tualatin Mountain Forest property.
Access
Access to the property is available to NWTA members and their guests provided the following criteria are met:
- NWTA membership is current, and member is in good standing nw-trail.org/join/
- Members/visitors must adhere and agree to OSU research forest visitor policies, which can be found at https://cf.forestry.oregonstate.edu/recreation/visitor-information
- Bike bands and parking tags are no longer required.
Note: The Tualatin Mountain Forest (Rocky Point Trail System) maps on Trailforks have recently been updated. This most recent update makes viewing the maps much easier for NWTA members, and eliminates nearly all of the steps previously needed.
However, if you find you are still encountering issues, we advise the following:
- Refresh and/or reload the Oregon region manually.
- The Trailforks app, like most apps, will routinely refresh on your phone. However, refresh schedules are different user to user and may also depend on your phone’s app configuration (for example, limiting updates without Wi-Fi). This is why a manual refresh or reload is recommended.
- Trails with restricted access settings, such as the Tualatin Mountain Forest, are visible to all accounts (both Pro and free accounts). Please note that free accounts only allow one region at a time to be downloaded. If you are receiving an error message as a free account user trying to download Oregon, please ensure you have no other regions downloaded.
History
The trails out at Rocky Point are said to have originated as horse and moto trails. People have been riding bikes out at Rocky Point at least since the 1970s. It started on touring bikes mostly on gravel roads, but with a bit of venturing in on the singletrack. With the advent of mountain bikes in the 80s, folks started to make a more concerted effort to make the trails functional for bikes. In 2019 NWTA and previous landowner Weyerhaeuser entered into a lease agreement, which allowed NWTA to manage access through its membership. Since then the trail system has been transformed with thousands of hours of trail building and maintenance. In 2025, the land was acquired by Oregon State University to be managed as the Tualatin Mountain research forest with recreational access.
A note from NWTA about the 2025 transition of the Tualatin Mountain Forest (Rocky Point) property to Oregon State University:
NWTA knows the Rocky Point trails are near and dear to so many members. The Rocky Point trail system, historically referred to as the Scappoose trails, was officially brought online in 2019 when NWTA signed a recreational lease with the previous landowner. Under NWTA’s stewardship, the property has become the closest major mountain bike trail system to Portland with nearly 40 miles of trails – while still very much maintaining its primary designation as a commercial forest.
After a number of years in process, the Trust for Public Land (TPL) has acquired the Rocky Point property and transferred ownership to Oregon State University (OSU), to be managed by the College of Forestry as a research and demonstration forest known as the “Tualatin Mountain Forest.”
The intent is — and always was — to include and enhance public access to the property as part of OSU’s research, education, and outreach priorities for the forest. There is no indication that recreational access, specifically mountain biking, will be removed from the property.
NWTA Leadership is in regular communication with OSU and has signed a partnership agreement for trail stewardship similar to those we hold with our other 10+ land management partners. Under the new agreement with OSU there will be no immediate changes to NWTA member access to the Tualatin Mountain Forest (“Rocky Point”).
NWTA is supportive of and excited for the potential under this new partnership. Public access is a key part of OSU’s vision for the Tualatin Mountain Forest. The College of Forestry plans to offer recreational opportunities on the forest in the future, carefully balancing these with research and demonstration activities. And importantly, OSU’s stewardship of the land as an actively managed research forest will protect this area from future development.
OSU is very conscious of the fact that maintaining access provides much-needed outdoor recreation opportunities close to Oregon’s diverse population center. NWTA has built a great relationship with the current landowner, and we welcome continuing to build a relationship in forest research, education, conservation and recreation with OSU.
Most importantly, thank you all for your continued membership, donations, volunteerism and all-around amazing support of NWTA that helps make great strides like this possible. We couldn’t have come this far in advancing the sport for all without you!
