At a Glance

  • Remote old-growth Coast Range river corridor
  • One of the quieter trails in the Siuslaw, rarely crowded
  • Old-growth Douglas fir and bigleaf maple river banks
  • Good spring and fall birding along the riparian corridor
  • Accessible without the long forest road approach of Kentucky Falls

Overview

The North Fork Siuslaw Trail follows the upper course of the Siuslaw River's North Fork through a Coast Range river corridor that most visitors to the Siuslaw National Forest never find. While the cape, dunes, and waterfall trails draw the majority of hikers, the North Fork provides a different experience: a sustained river valley walk through old-growth Douglas fir and bigleaf maple with minimal company and the kind of quiet that is increasingly rare in the Coast Range.

The trail gains 800 feet over 4 miles, mostly in gradual steps as the corridor rises toward its headwaters. The river is audible throughout most of the route and accessible at multiple points. Old-growth trees in the valley bottom include Douglas fir over 200 years old and bigleaf maple with moss-covered branches that arch over the river.

This trail is within Siuslaw National Forest in the southern portion of the forest, inland from Florence. The forest road approach is longer than for the coastal trails but not as extended as the Kentucky Falls drive.

The Route

Miles 0 to 2.0: Lower Fork Valley

The trail begins near the North Fork and follows its eastern bank upstream. The forest in this section is a mix of old-growth and mature second-growth, with old-growth becoming more prominent in the undisturbed valley bottom. Several river viewpoints provide looks at the clear water and gravel bars.

The trail is well-maintained in the lower section with consistent trail tread and no significant obstacles.

Miles 2.0 to 4.0: Upper Valley and Cascade Zone

The upper section of the trail enters older and denser forest as it follows the river into a narrowing canyon. Several creek tributaries join the main channel here, and small cascades are visible at the tributary junctions.

The trail becomes slightly less distinct in the upper section as traffic thins. The tread is still clear but occasional blowdown requires minor route-finding. The turnaround point at 4 miles is near a particularly scenic section of river with old-growth on both banks.

When to Visit

April through November is the comfortable season, with spring (April-May) offering the best combination of high creek volume and trail dryness. The road access can be problematic in heavy rain periods during late fall and winter.

What to Bring

  • Rain gear for shoulder season visits.
  • Many hikers carry 1.5 to 2 liters of water. River water requires treatment. Individual needs vary.
  • Waterproof footwear: the trail edges can be muddy in wet conditions.
  • An offline map. Cell service is absent throughout.

Practical Details

Northwest Forest Pass required (as of 2026). No restrooms at the trailhead. Dogs are allowed and must be leashed. Dispersed camping permitted with standard LNT practices; see the Leave No Trace guide.

For veterans and active military free pass programs, see veteran benefits for national forests. Check current conditions for road status before heading out.

Getting There

From Florence, take Highway 126 east approximately 8 miles to Mapleton. From Mapleton, take North Fork Road north and east, following it approximately 20 miles to the trailhead. The road is paved initially and transitions to gravel. High-clearance vehicle recommended for the gravel sections.

From Eugene, take Highway 126 west toward Mapleton (approximately 50 miles) and then follow North Fork Road as above. Total drive from Eugene is approximately 75 miles.

Cell service ends before you reach the trailhead. Download offline maps and GPS coordinates before leaving pavement.

Trailhead Parking

Frequently Asked Questions

How remote is the North Fork Siuslaw Trail?
The trailhead is accessible via gravel forest road about 20 miles from Florence. Once on trail, the area sees light use and the river corridor has a genuinely quiet character. It is not backcountry remote but it is far less visited than the coast and dune areas of the Siuslaw.
Is the North Fork Siuslaw a good winter hike?
The low elevation makes it accessible most of the winter, though the access road can be problematic after major rain events. Winter brings the highest creek volumes and the most dramatic river character. Expect wet conditions.
What wildlife might I see on this trail?
Roosevelt elk are present in the North Fork drainage. River otters have been reported along the creek. Black bears are active in the forest. Spring and fall migrations bring a variety of songbirds and waterfowl through the riparian corridor.
Are there any waterfalls on the North Fork Siuslaw Trail?
The trail passes several cascades and creek drops that qualify as small falls, though nothing comparable to Kentucky Falls or Sweet Creek Falls. The appeal here is more the overall river corridor character than specific waterfalls.
Can I fish on the North Fork Siuslaw?
The North Fork Siuslaw River supports wild steelhead and cutthroat trout. Fishing regulations apply; check current ODFW regulations for the Siuslaw drainage before fishing.
