East Fork Trail #139 is a 10 mile lightly trafficked out and back trail located near Stevenson, WA that features a river. The trail is rated as moderate and primarily used for hiking and fishing.
Out and back trail that follows along the East Fork Lewis River up to Little Lookout Mountain. Trail is 5 miles out, and 5 miles back. The trail starts at the Forest Road 4200-514 bridge, crossing the East Fork Lewis River. The trail follows the East Fork upstream. 1 mile from the start, the East Fork must be crossed at a ford which may be difficult during periods of high water. Beyond the ford the trail continues upstream another 1 mile to a second ford near Poison Gulch. Beyond the second ford the trail climbs steeply toward Little Lookout Mountain and it ends at Forest Road 41.
After passing this trail head 2 weekends in a row on my way to/from Zig Zag Lake, I just had to check it out. It does take a while to get there, I already live in Battle Ground and it still takes approx 1 hr to get to the trail head. Plenty of parking (5-6 cars easy) for a trail that has very light use. We only made it about 2.5 miles in before we turned around, got a late start. The trail for the first mile was very easy. We had to use the loppers to cut through some over growth of blackberry-like bushes. There were a few places that were muddy as water was crossing over to get to the river. At 1 mile we reached the river and switched from our hiking boots to water shoes to cross the river. It was pretty easy this time of the year as the water was pretty low, never more than mid calf high. There is a pink ribbon on each side of the river to let you know where the trail is. The next mile to the second river crossing was nice as well. Mostly flat but still heavily forested. After crossing the river, where we were able to just walk across rocks. From this point you really start to climb. The next half mile we went from 1750' to 2000' and the trail just keep climbing. Along this path you see a lot of old growth trees that are charred from the 1902 Yacolt Brun. The trail had some stretches that were very narrow and/or slanted down hill. It was not that hard, but you do have to pay attention to to your steps. The 2 river crossings are very cool visually. Because we had to cut our way through 4-5x on the way in, it took about an extra 30 min. But we went a total of 5 miles (out and back) in 3h50m going at a steady pace and stopping to take in the views. I am looking forward to hitting this one again and getting all the way to the end Little Lookout Mtn. 4000'.
