The Ah-Pah Interpretive Trail is an easy redwoods hike near the north end of Prairie Creek Redwoods State Park. Most people drive right by it, usually because they’re headed to the more popular hikes located farther south along Newton B. Drury Scenic Parkway. But if you want a short and level walk through beautiful redwood scenery with likely no one around you, then the Ah-Pah Interpretive Trail may be just what you need.

Bonus: informational signs describe how Redwood National & State Parks personnel removed the Ah-Pah logging road and then rehabilitated the slope. The work was done so well and the vegetation has grown so fast that you’ll hardly believe a road was ever here.

Hiking the Ah-Pah Interpretive Trail

Start walking level on the path that was once Ah Pah Road as you look out to the left over a small drainage that feeds McGarvey Creek. Quickly reach the first of three signs you’ll encounter over the first 0.1 mile that explain the environmental benefits of removing the road and how the process was actually completed.
You’re contouring along an open slope that features a good assortment of redwood trees large and small in an open forest. Lots of sword ferns and lady ferns line the trail, and you’ll also see salal, rhododendrons, thimbleberry, red huckleberry, and black huckleberry. You’ll hear a bit of traffic from Newton B. Drury Scenic Byway, but it fades as you progress deeper into the redwood forest.
At 0.2 mile you’ll arrive at the Chas L. McKelvy Memorial Grove, which has several downed trees, and then pass through a small grove of red alder trees. Continue on another 0.1 mile to the official end of the Ah-Pah Interpretive Trail at Merriman Grove, which features some impressive redwood trees.

I visited this trail a couple of years ago. Highly recommended! As you say the recovery of the landscape has been remarkable, and with the rapid, lush growth in this coastal forest there’s barely any sign that there was once a road here. Visitors with extra time can view an interesting contrast with the recovery of another road that was decommissioned at about the same time, through similar methods–the Steinacher Cr. Rd. up the Salmon River Rd. out of Somes Bar, Calif. Drive the stub end of the road across a high bridge over the Salmon River, to its end about 1/4 mile beyond. From there, the first part of the Steinacher Cr. Tr. follows the route of the old road bed. In this much dryer climate, recovery has been much slower–but still quite good–and the remainders of the old road cuts aren’t hidden under vegetation.
It’s been a while since I’ve been near Somes Bar. Sounds like an interesting trail!
