West Ridge Trail to Karl Knapp (formerly Prairie Creek) Trail Loop

Overview

This is a classic Prairie Creek Redwoods loop that links airy ridgetop forest with cathedral-like creekside redwoods. Starting and ending at Prairie Creek Visitor Center, the West Ridge → Zigzag #1 → Karl Knapp route runs about 5.7–6.0 miles total with roughly 800–900 feet of elevation gain. Plan on 2.5–3 hours depending on pace and how often the trees stop you in your tracks. If you want more variety than a flat stroll but still crave those “giant redwoods up close” moments, this loop nails it.

Route Snapshot

Head out from Prairie Creek Visitor Center and climb West Ridge through dense old-growth. Expect rolling terrain and some steeper switchbacks—nothing technical, but you’ll feel it. At Zigzag Trail #1, drop to the valley floor and pick up the Karl Knapp Trail for an easy, mostly flat return along Prairie Creek. Karl Knapp delivers the goods: dark, almost gothic groves of impossibly tall, slender trees, redwood benches to pause on, and stretches where the path runs beside a wide, shallow creek. In late autumn, watch from the footbridges for Coho salmon moving through the water.

What Stands Out

The contrast is the point: West Ridge’s higher, quieter forest and then Karl Knapp’s lush lowland giants right at creek level. It’s a more rewarding day than sticking only to the flats, but you still end with a gentle, scenic cruise back to the visitor center instead of pounding downhill to your car.

Difficulty and Conditions

West Ridge and Zigzag #1 bring the effort with sustained ups and downs; Karl Knapp is the cool-down. In winter, a small seasonal footbridge on Karl Knapp is removed; you may need to wade a shallow, rocky-bottomed channel that’s often just a few inches deep. Traffic noise from Newton B. Drury Scenic Parkway can be audible in places, though it’s much less noticeable when the parkway is periodically closed. Cell coverage is limited—grab a paper map before you go.

Logistics

Start and finish at Prairie Creek Visitor Center (restrooms available). Parking is usually free along Newton B. Drury Scenic Parkway or under the redwoods on the road to the campground; paid parking is just past the campground kiosk. Summer fills early; larger vehicles typically use the Elk Meadow stretch of the parkway. No day-use permit needed, and pets aren’t allowed on park trails.

Best Time to Hike

Year-round is fair game thanks to the redwoods’ shade and coastal air. For salmon viewing, aim for late autumn. If you can, go early for softer light through the canopy and fewer people; on select days when the parkway is closed, the forest feels especially quiet. Winter hiking is beautiful, but be ready for that short creek wade on Karl Knapp.

Easier Alternative

If you want the redwood magic without the climb, the 2.5-mile Karl Knapp–Foothills–Cathedral Trees loop starts at the same visitor center and stays mostly flat while still visiting big trees and bridges along Prairie Creek.
