Triangulation Creek

Deep in the Tillamook State Forest lies rarely seen and rarely descended Triangulation Creek. With multiple access points, and multiple side falls this area has several options for exploration, but has a fairly high pay to play for most folks and high clearance vehicle is preferred. Flow will be a trickle by the beginning of summer so catch it early. On the shuttle make sure to stop at Triangulation Point for a 360 Degree view, also a common destination for OHVs.

Depending on logging operations some options for getting into the area may be blocked. Known routes into the area include Cedar Creek Road that starts at Jones Creek Campground, Cedar Butte Road near Keenig Creek Campground, and Kilchis River Forest Road out of Tillamook. Once in the area some logging operations may also effect road conditions. At the 5-Way intersection marked on the map you can drive West and shorten the approach instead of going up to Triangulation Point but this was a muddy mess in March 2025 and then you miss the nice view at the top. From the parking location follow the old road grade down around the first turn, shortly after find an easy spot to head down off the road into the trees. The approach is through relatively open forest sometimes following game trails, some times crossing road grades. If it gets steep you are too far DCR.

Immediately below R4 are 2 downclimbs.
