Existing Off-road Cycling Trails and Facilities

The City of Portland allows off-road cycling in seven City-owned locations. These include trails in Forest Park, Powell Butte Nature Park, and Mt. Tabor Park, as well as bike parks at the New Columbia Bicycle Skills Park and Ventura Park. In addition, the Portland International Raceway is open to off-road cycling for competitive events. Gateway Green is planned for off-road cycling trails, but is not yet developed. The inventory maps the off-road trails and bike parks at each of these locations that are open to people on bicycles. View printable maps below, or visit the Off-road Cycling Master Plan interactive map.

Forest Park

At 5,172 acres, Forest Park is the largest forested natural area within city limits in the U.S. Connected to the Pacific Coast Range, the park stretches for nearly eight miles along the northeast slope of the Tualatin Mountains and is home to multiple species of animals, birds, trees and plants. Over 70 miles of trails and lanes traverse the park, providing opportunities for hiking, trail running, off-road cycling, wildlife watching, and other nature-based activities. Approximately 28 miles of trails, service roads and fire lanes are open to off-road cycling. Nearly all are wide trails or service roads. 

The Forest Park Natural Area Management Plan guides land management decisions within the park, and balances goals within three management units: South, Central and North. The plan also includes unique trail design guidelines that supersede the citywide trail design guidelines, and bases recreation improvements on the carrying capacity of the park. The City and its partners have developed a variety of surveys, reports and initiatives to support the management and enhancement of the park. For example, the City has established Desired Future Conditions for the park and uses Ecological Prescriptions as well as the Forest Park Project Objective Screening Tool to guide and select proposed park management activities and improvements.

In 2010, the City considered ways to improve and expand singletrack cycling opportunities in Forest Park, which were documented in the Forest Park Single Track Advisory Committee Report and Cycling Actions.

The Forest Park Conservancy, a nonprofit organization that advocates for and assists with stewardship of the park, works closely with the Portland Parks & Recreation to monitor trail conditions and organize volunteer restoration efforts.

Powell Butte Nature Park

This 612 acre park, owned by the Portland Water Bureau and managed by Portland Parks & Recreation, is a natural area with meadowlands, forest and wetlands, accessible to the Springwater Trail. The park is in the headwaters of Johnson Creek, an urban creek with remnant populations of native salmon and steelhead. A 100-acre area in the southeast portion of the summit is designated exclusively for wildlife habitat with limited public access. Two underground reservoirs in the park provide drinking water storage.

There are eight miles of trails in Powell Butte Nature Park open to people on bicycles, including a mixture of unpaved singletrack, narrow, mid-width, and wide trails and paved trails. The Powell Butte Master Plan determines the allowed uses in the park and identifies the location and types of trails. The Friends of Powell Butte provide volunteer services at the park.

Mt. Tabor Park

Mt. Tabor Park, at 191 acres, serves the entire city as well as its adjacent eastside neighborhoods. The park is owned by the Portland Water Bureau and managed by Portland Parks & Recreation. Designed as a naturalistic landscape in the 1930s with one underground and three open reservoirs managed for public water supply by the Portland Water Bureau, the park was significantly renovated in the 1990s to improve park facilities and to restore natural areas. The Mt. Tabor Park Master Plan prioritizes continued management of active areas and facilitation of the long term health of the forest and meadow environments in the park.

Off-road cycling is permitted on 5.5 miles of designated trails. The Friends of Mt. Tabor Park provide volunteer maintenance assistance within the park.

Ventura Park Pump Track

This 7.25-acre park includes play areas, a playground and Portland’s first pump track which opened in 2012. The dirt track allows riders to complete a loop without pedaling, using banked turns and rolling hills to maintain momentum. There is an entry-level and an intermediate level track, built and maintained by the Northwest Trail Alliance (NWTA). The park provides opportunity for exercise and bicycle skill building in the Hazelwood neighborhood in East Portland.

New Columbia Skills Park

Owned by Home Forward, New Columbia Skills Park is located on one half of a pocket park at the corner of North Woolsey and Trenton, adjacent to Rosa Parks Elementary School. Funded by the Portland Development Commission and constructed by the Community Cycling Center, this skills park directly serves the neighborhood’s 2,500 residents and is open to all members of the public during daylight hours, providing a safe riding area for all ages. The park also includes the Bike Repair Hub, staffed by Community Cycling Center volunteers.

Portland International Raceway

Owned and managed by Portland Parks & Recreation, the 291-acre Portland International Raceway (PIR) includes a nearly two-mile paved loop racetrack. PIR receives no City funding but generates revenue for operation and maintenance on-site through a broad spectrum of motorized and non-motorized races and events. The Portland International Raceway Master Plan describes allowed uses and planned environmental restoration at the site. Short track cross-country mountain biking and cyclocross races occur on temporary courses set up in the motorcross course and through grassy areas adjacent to the paved racetrack. Off-road cycling is limited to programmed events.

Gateway Green

This 25-acre island between I-84 and I-205 just north of the Gateway Regional Center and east of Rocky Butte was recently purchased by Portland Parks & Recreation. In partnership with the Friends of Gateway Green, a nonprofit dedicated to creating a sustainable recreational facility on this unused property, the site is planned for singletrack trails with integrated skills features, a tot track with skills features and play area, a pump park, a flow trail, beginner, intermediate and advanced jump lines and a dual slalom course. The site may also be used for cyclocross events. The I-205 multi-use path runs along the western edge of the property, providing access to the site by bike via the 40 Mile Loop. The Gateway Regional Center provides transit services to the site from three MAX train routes.

The Friends of Gateway Green hosted Community Cross, a family-friendly cyclocross exhibition race for all ages and abilities, at the site in 2014. The Northwest Trail Alliance is partnering to construct interim trails to be used for off-road cycling camps hosted by the Community Cycling Center in summer and fall of 2016. The Northwest Trail Alliance and the International Mountain Bike Association will be assisting in design of the planned facilities.
