Hiking East Fork Lewis River

If you like rugged, primitive trails, creek crossings with no bridges and finding a great view at the end of the trail, this hike is for you.

The East Fork of the Lewis River Trail is a little bit off the beaten path so it doesn't get much maintenance, but it doesn't get crowded either. The trail starts out crossing the river on an abandoned car bridge. The first miles is an old road bed overgrown with alder, and WTA volunteers have reshaped the trail bed to transform its straight lines into a more natural "trail shape". There are two creek fords that can run high after heavy rains and then after about a mile the route goes across the river and is only passable when the water is low (Summer through early Fall usually - depending on how much you like to wade).

On the other side the trail continues on an abandoned road, but the alders are taller and lush sword ferns abound. About two miles in you pass some flat areas that might do for small campsite right along the trail. Then you cross the river again but by now the river has diminished in volume and the crossing is less scary. Beyond this crossing evidence of the old road disappears altogether and the forest thickens. Every so often there is a huge fire scarred old growth trunk; like tombstones commemorating the 1903 Yacolt Burn that swept through the area.

The last couple miles climb steadily upwards and the trail starts to disappear, covered over by ferns and other vegetation. As you ascend the south facing slope, it gets drier and the trees smaller and more dispersed allowing glimpses of Lookout Mountain above.

Finally the trail ends at spur road 599. From there you can follow 599 to the saddle between Little Lookout Mountain and Lookout Mountain at about where 599 intersects road 4220. There is a great view of Mount Hood. To get a little higher up scramble up another eighth of a mile to the rocky summit of Little Lookout Mountain (4,000 feet).

Due to a backlog of maintenance concerns WTA added this trail to a list of places to prioritize as part of the "Lost Trails Found Campaign". 2017 project work on this trail supported by a generous Matching Awards Program Grant (MAP) from the National Forest Foundation.

WTA worked here in 2022, 2021, 2020, 2019, 2018, 2017, 2016 and 2011!

WTA Pro Tip: Save a copy of our directions before you leave! App-based driving directions aren't always accurate and data connections may be unreliable as you drive to the trailhead.

Getting There

Go north on I-5 from Vancouver and take exit 9, then drive Highway 502 east for 7.7 miles to Battleground. Or, from I-205 from Vancouver, take Highway 500 East (Exit 30) which turns into 503 north to Battleground.

502 (Main Street in Battleground) and 503 (Lewisville Highway) intersect in near a mini-mall with a Safeway. Head north on 503 for about 6 miles. Turn right on Rock Creek Road and go about 8 miles continuing past Lucia Falls and Moulton Falls.

Turn right on Sunset Falls Road just past Moulton Falls. Continue east for about 7 miles. Continue past Sunset Campground. The road now becomes FS Road 42 as you enter the Gifford Pinchot National Forest.

Follow 42 for about 5 miles of bumpy potholes and look for a wide spot on the right side of the road. The trail begins on an abandoned road that is blocked with boulders and largely grown over with vegetation.
