| Other Names | Jordan Cr. & Diamond Mill, Jordan Creek, Jordan Creek OHV Area, Tillamook State Forest, North Fork Wilson River, Jones Creek, Runyon Creek, Cobmaster, Deerfence, Elk Wallow Rd, Smith Homestead Day Use Area |
| Last Known Status | Open |
From the novice play ride area surrounding the campground, to the logging runs to the peak with great views, to the deep woods single track, to the steepest crustiest climbs in Tillamook, this area has something for everyone.
The upper trails are narrow and difficult with very few chances to turn around. Motorized trails are marked and rated on trail maps and kiosks, but not necessarily on the trails themselves, and regions of the area close with changing fire, logging, and ecological conditions, so pay attention.
The most inviting swimming hole you'll ever see sits in the back right corner of staging area (under the wooden arch bridge) with crystal clear water, smooth rocks, and natural stone steps. There are more swimming areas in the surrounding park as well.
This area gets busy on weekends and only a couple of the camping sites have picnic tables and shade, but you can have the whole place to yourself mid-week. With cheap camping, a wide range of difficulty, and new trails being added periodically, this park is an all around winner for the family.
