Oaks Bottom Wildlife Refuge is a 163-acre floodplain to the Willamette River and consists of meadows, woodlands, and wetlands. This out and back proposed hike will allow visitors to experience a little bit of everything Oaks Bottom has to offer.

Description of Trail

The paved North Woodland Trail begins just behind the bollards at the south end of the parking lot behind the bollards and restroom. Traversing this trail from the beginning, park visitors will experience forested areas with shaded canopy cover and a general downhill grade of 5%. Rustic cedar fencing lines some sides of the trail in protected habitat areas. Visitors can expect to hear road noise, frogs, and birds. This trail is frequented by runners and bicyclists and is wide enough for multiple people to pass. 

There are two sets of seven-foot long rumble strips roughly 500 and 650 feet down the trail.

The beginning of this trail includes sections of compact soil and gravel as well as sections of looser gravel. This trail has had many improvements made recently, therefore the gravel is not as compact in those new sections.

Coming up to the next trail junction, visitors may continue to the right, or for the proposed hike, visitors may continue down to the left on a newly built gravel ramp or use the adjacent set of stone steps. There is no railing accompanying this ramp and has a grade of 10-12% over 22 linear feet. There are three steps leading down made from stone and gravel.

Once down the ramp, visitors will cross a 25-foot-long wooden bridge with a width of 57 inches, railing, and mesh wire covering most of the base of the bridge. This wire may be loose in places and gravel from the trail may be built up on the lips of each end of the bridge.

Bridge crossing features wire mesh on wooden planks for traction in wet conditions.

This section of trail is by no means “smooth.” There are some small sections of loose gravel, some protruding roots in the center of the trail, protruding rock edging on the downhill side, and ponding during wet seasons.

The first true rest spot is 646 feet into the gravel portion of trail. This pullout is semicircular with a max width and depth of nine feet and four feet, respectively. After this pullout is an uphill grade of 5.5-6% over 15 linear feet.

Nearing the main viewpoint, there is another major downhill grade of 7% for 25 feet. Beyond this, visitors will arrive to the viewpoint just over 1,000 feet from the start of the Oaks Bluff Trail, or 2,600 feet from the trailhead. The viewpoint is a semicircular gravel pad on the uphill side of the trail with a maximum width and depth of 16 feet and five feet, respectively. Visitors can expect to see deer, birds, and activity from beavers.

From here, visitors may choose to turn around and head back the way they came or continue further down the gravel trail. If visitors wish to continue, the trail quality itself is similar to what they have already traversed and does not include decent turnaround locations and starts to get rockier after a few hundred feet.
