Sunday. Cloudy. 12 people + 1 dog. Another hike led by Lou, the 71 year old, who just did Larch Mt in the rain yesterday (16 miles). 7am meeting. But one was late by 20 minutes. At trailhead at 8:15, after a bathroom stop at a Mcdonald off junction of Hwy 6. Then we waited for the drivers to shuttle cars to the Keenig Creek TH 7.5 miles down the road. We didn't start until close to 9am. We finished at 4:30pm. Craig's GPS says 18 miles and 3100' gain. 7.5 hours (including multiple stops of 1+ hour) is not too shabby. The entire trail actually starts at Elk Creek TH, which makes it longer. There're a number or other starting points along this trail, making it mendable according to your time/fitness level. An area map is on this PDF.
Many small creek crossings and falling waters. The river is rushing with force. Not a bad hike. 0.1 mile in from King Mt TH is a 4 way cross-section. Up ahead is King Mt summit (in 2.4 miles, and hit Elk Mt trail is in 3.7 miles), to the right is Wilson River trail (goes to Elk Creek TH in low elevation). We took the left (7.4 mile to Jones Creek TH, 10.9 to Footbridge TH, and 17.1 to Keenig Creek TH). The first couple of miles go up, not steep. Good trail. 
A very nice bridge when we hit road again, where a dirt bike trail is located nearby (Diamond Hill) and big parking lot and privy. Craig tried his water-wading idea: two big bags over his legs. Then, it's flat and following the river to Jones Creek TH. 
Tillamook Forest Center is closed with 2 padlocks on each side. Picnic tables and benches. More easy walk until Foodbridge TH. Then it's uphill and back down to the end.
