Facility Overview
Cornell Tunnel Parking is a dedicated open-air roadside trailhead parking turnout located at 3596 NW Cornell Road in Portland, Oregon. Perched within the lush, verdant West Hills along the southern boundary of Forest Park, this parking area sits immediately west of the historic Cornell Tunnels—iconic arched passages originally constructed by the Works Progress Administration (WPA) in 1940–1941. The lot layout consists of a linear pull-in surface turnout situated directly along the roadway, framed by the towering native tree canopy of Balch Creek Canyon. Because the lot is an open-air surface area, there are no overhead ceiling height restrictions within the stalls themselves. However, drivers of oversized vehicles, tall camper vans, and RVs must exercise caution: the adjacent historic Cornell Tunnels feature arched masonry clearance that limits overhead passage, and the roadway itself is narrow and winding. Standard passenger cars, crossovers, compact SUVs, and light pickup trucks can navigate and park here without issue.
Prime Location & Nearby Attractions
Serving as one of the most scenic entry points to Forest Park—one of the largest urban forest reserves in the United States—this parking area is a favorite launch pad for outdoor recreation and historic sightseeing. The turnout provides immediate on-foot access to the Tunnel Trail, Cumberland Trail, and the world-renowned 30-mile Wildwood Trail. From this location, hikers and runners can complete a moderate 0.8-mile uphill trek to the historic Pittock Mansion, which delivers breathtaking panoramic views of the Portland skyline, the Willamette River, and Mount Hood. A short descent into the canyon brings visitors to Balch Creek and the storied stone ruins known as the Witch's Castle (Stone House) in Macleay Park. Additionally, the Bird Alliance of Oregon (formerly the Audubon Society of Portland) and its wildlife care sanctuary are located less than a half-mile further west along Cornell Road. For dining and shopping, the bustling Northwest 23rd Avenue shopping district and Nob Hill neighborhood are just a five-minute drive down the hill.
Access, Navigation & Transit Connectivity
Access to Cornell Tunnel Parking is directly off NW Cornell Road. Drivers traveling westbound from downtown Portland and the Pearl District ascend NW Lovejoy Street, which seamlessly transitions into NW Cornell Road before threading through the historic tunnels. Eastbound motorists approach from Cedar Mill and NW Skyline Boulevard, winding down through the hills. The roadway is two-lane, twisty, and framed by steep rock walls and forested hillsides, requiring attentive driving and adherence to posted speed limits. Highway connectivity is convenient: NW Cornell Road quickly links down to NW 23rd Avenue, US-30 (St. Helens Road), and the I-405 / I-5 freeway junction via the Fremont Bridge. Public transit does not stop directly at the tunnel due to the winding mountain terrain, but TriMet bus lines (such as Line 15 and Line 77) serve the lower neighborhood trailheads at NW 23rd & Lovejoy and NW Thurman & 28th, allowing ambitious hikers to ascend into the park.

Visitor & Driver Tips
Because this trailhead turnout has limited capacity (holding approximately 8 to 10 vehicles), spaces fill rapidly on sunny weekends and peak morning hours. Arriving early in the morning or during mid-week hours ensures the best chance of securing a space. While parking is free, drivers should practice standard urban park caution: never leave backpacks, electronics, or personal belongings visible inside your vehicle, as trailheads can be targeted by opportunistic car prowlers. When entering or reversing out of the turnout, use extreme vigilance and listen carefully; blind curves and tunnel acoustics along NW Cornell Road can mask approaching vehicular, cycling, and pedestrian traffic. Finally, because cell reception can be spotty in the deeper pockets of the canyon, it is advisable to download your hiking maps and GPS directions prior to ascending the hills.
