Beginning in the Whittaker Creek Campground, the steep Old Growth Ridge Trail ascends 750 vertical feet over a mile’s length, topping out at a peekaboo viewpoint over the Siuslaw River. Benches and interpretive panels along the way allow a moment to catch one’s breath. A short spur trail descends slightly to a lightning-struck Douglas Fir tree. The unique site and setting of the Old Growth Ridge Trail and its newer Armantrout Loop segment make it nationally significant, earning it National Recreation Trail status.

Know Before You Go:

• The trailhead is located between campsites 23 and 24 on the opposite side of the campground loop road.
• Visitors can park in the campground day use parking areas. During the winter when the park is closed to access, they can park near the entrance or in the boating area opposite the campground on the river. Please do not block the gate and use caution if parking along the major haul road.
• Trail boardwalks can be very slick when wet; use caution when traversing them.
• The day use area and 31-site campground are open from Memorial Day to Labor Day. This is a first-come, first served campground opportunity.

Point of Interest:

On the return from the top, take the Armantrout Loop Trail at Alden Glen trail junction. This 1.4-mile alternative has eight switchbacks to maintain a gentle grade on your way back to the trailhead.

From Eugene, OR: Travel west on Highway 126 through the forested foothills of the Coast Range. Turn left on Siuslaw Road (about 40 miles). Travel 3 miles, watch for signs to the campground located on your right.
