About this spot

This location features a circa 1900 log hoist structure originally used to lift logs from the Willamette River onto railroad cars positioned on the bank above. The facility processed logs from various sources including the Astoria area via tugboats and stern wheelers, sorting mixed timber species before hoisting operations six times daily to transport loads to Oregon City. The operation employed up to twelve workers before closing in the late 1920s. A residential structure was later built atop the hoist but remained unoccupied due to inability to connect municipal sewer services. The structure presents significant structural concerns. Access involves shimming across a tree branch and navigating a roof with numerous deteriorating sections. Ascent relies on a small rope ladder with bent roofing nails serving as handholds, creating unstable climbing conditions. The primary jump platform integrity is questionable, and the overall building stability outside the main concrete core is compromised. A longer ladder system would be needed to access a larger opening on the structure's rear side. A cement pathway leads directly to the building with a trail branching downward from the main path. Access from Portland requires taking I-205 South to exit 8 for State Route 43 toward West Linn/Lake Oswego. Turn right onto OR-43 N and continue approximately 4.4 miles to a traffic light at McVey Avenue. Turn right onto Green Street (sign may not be immediately visible when passing). Follow Green Street into the park, park your vehicle, and walk toward the water. Cross the visible bridge and turn left onto the path leading downward to the location on the left side.

Safety first. Cliff jumping is inherently dangerous and can cause serious injury or death. Conditions — water depth, submerged hazards, and access — change constantly. CliffScout is community-sourced reference information, not a guarantee a spot is safe. Always assess the conditions yourself before jumping, and never jump where you're unsure. You assume all risk.
