Many cyclists find street parking in neighborhoods adjacent to the park, particularly near popular access points for Leif Erikson Drive or other fire lanes.

Yes, Forest Park is generally dog-friendly, but specific rules apply. Dogs must be kept on a leash at all times while on trails and fire lanes within the park. Please remember to clean up after your pet to help maintain the park's natural beauty.
The best time to cycle the Forest Park loop is typically during the spring, summer, and fall months when the weather is milder and rainfall is less frequent. The deeply forested nature of the park provides cool, shady conditions, making it pleasant even on warmer days. Winter cycling is possible, but be prepared for wet conditions and potentially slick surfaces.

This road cycling loop features a mix of surfaces. You'll encounter paved roads, but also significant sections of hard-packed gravel fire lanes, such as Leif Erikson Drive. While a road bike can manage, some unpaved sections might be more comfortable on a cyclocross or gravel bike due to the varied terrain and potential for loose gravel. The route also includes substantial elevation changes with climbs and descents.
Along this route, you'll experience the immersive beauty of one of the largest urban forests. A notable highlight is the View of Saint Johns Bridge, offering a picturesque vista. You'll also pass through the serene Adams Property, surrounded by lush forest. The entire ride offers a feeling of being deep in a Pacific Northwest forest.
Yes, this route utilizes and intersects with several other trails and fire lanes within Forest Park. You'll find yourself on sections of the Wildwood Trail, Northwest 24th Bicycle Boulevard, Northwest Firelane 1 Road, Skyline Trail, Lower Macleay Trail, and Jay Trail, among others. The park's extensive network allows for various connections.
This 50 km (31 mile) road cycling loop typically takes around 1 hour and 59 minutes to complete. This duration can vary based on your cycling pace, fitness level, and any stops you make to enjoy the scenery.
This loop is rated as moderate difficulty, requiring good fitness due to its distance and significant elevation gain of nearly 700 meters (2,300 feet). While sections like Leif Erikson Drive have a gentle grade, linking them with other fire lanes and roads can involve steep ascents. Beginners with good fitness might find it challenging but rewarding; those new to road cycling or hill climbing may prefer shorter, flatter routes initially.
The route offers an immersive experience within a deeply forested, unspoiled landscape with cool, shady drainages. You'll be surrounded by diverse native plants and have the chance to spot various wildlife, including over 100 kinds of birds, as well as mammals, reptiles, and amphibians. It's a true escape into nature just minutes from urban Portland.
While Leif Erikson Drive itself has a gentle grade, linking it with other fire lanes or roads can quickly increase the challenge with steep ascents like those found on Holman or Springville Road. Be prepared for these climbs. For optimal comfort on the mixed paved and gravel surfaces, some cyclists prefer a cyclocross or gravel bike over a pure road bike, especially if conditions are wet or the gravel is loose.
