Forest Park, Rock Creek Road, Linnton, and St. Johns Bridge loop

This loop is generally considered a moderate road cycling route that requires good fitness. It features challenging climbs and steep descents, so it's best suited for cyclists with some experience rather than absolute beginners.

The route is approximately 51.8 kilometers (about 32.2 miles) long with an elevation gain of around 780 meters (about 2,559 feet). While much of it is well-paved, some segments might be unpaved and difficult. You'll encounter serene and challenging climbs, like Saltzman Road, typically below a 4% grade, as well as steep and winding descents such as Newberry Road.

The loop offers diverse scenery. You'll cycle through the magnificent green canopy of Forest Park and enjoy fantastic peekaboo vistas of the Willamette River, Mount St. Helens, and Mount Adams from certain points. The iconic View of Saint Johns Bridge is a major highlight, and on clear days, you might even spot downtown Portland and Mount Hood in the distance. Other notable spots include Northwest Rock Creek Road and the Northwest Rock Creek Road View.

The best time to cycle this loop is generally during the spring, summer, and early fall months when the weather is milder and drier. This allows for more comfortable riding conditions, especially on the unpaved sections and steep descents. Winter cycling can be challenging due to rain and potentially slick surfaces.

Specific parking areas for this exact loop are not detailed, but Forest Park has various access points with parking. Given the loop's start and end points near Linnton and the St. Johns Bridge, looking for street parking or small lots in those areas would be a good starting point. Always check local regulations for parking availability and restrictions.

While specific public transport connections directly to the start of this loop aren't provided, Portland's public transit system (TriMet) serves areas around Forest Park and the St. Johns neighborhood. You may be able to take a bus that gets you close to an access point, though you'll likely need to cycle a short distance to join the main loop.

This route is primarily a road cycling loop, and while Forest Park itself has dog-friendly trails, cycling with dogs on a leash on busy roads or through challenging terrain can be difficult and unsafe. If you plan to bring a dog, consider shorter, dedicated multi-use paths rather than this specific road cycling loop.

No, there are no specific permits or entrance fees required for cycling on the public roads and trails within Forest Park that are part of this loop. However, always respect park rules and regulations, especially concerning trail usage and environmental protection.

The St. Johns Bridge is iconic, but its sidewalks are not wide enough for shared use by bicycles and pedestrians, which can make cycling across it a challenging experience due to traffic. Be prepared for potentially heavy vehicle traffic and exercise extreme caution if you choose to ride across the bridge itself. Many cyclists opt to view the bridge from nearby vantage points rather than riding directly on it.

Yes, the route incorporates sections of several other paths and roads. You'll find yourself on parts of the Wildwood Trail, Northwest 24th Bicycle Boulevard, Pettygrove Neighborhood Greenway, and Skyline Trail, among others, as you navigate this diverse loop.

Given the moderate difficulty and length of this loop, you should bring plenty of water, snacks, a repair kit (including spare tubes, pump, and tire levers), and appropriate cycling gear. Helmets are highly recommended. A phone for navigation and emergencies is also advisable, as some sections can feel remote.
