Trail Overview

Hamma Hamma Falls is a scenic drive through the lush Olympic National Forest that is perfect for beginners, families, and any vehicle looking to experience the breathtaking beauty of the Olympic Peninsula. This roughly 7.2-mile route follows Forest Road 25 (Hamma Hamma River Road) as it winds along the roaring Hamma Hamma River, climbing from an elevation of 558 feet to nearly 1,900 feet. The first portion of the drive is paved and relatively smooth, passing popular access points like the Lena Lake Trailhead, which offers excellent hiking into the wilderness. As the route continues, the pavement transitions to a gravel and dirt surface that, while easily passable for standard passenger vehicles, is notorious for containing numerous potholes that require slow and careful navigation. The ultimate reward of this journey is the stunning Hamma Hamma Falls, a dramatic two-tiered waterfall where the river plunges through a narrow rocky gorge, visible from the road's bridge crossing. A small parking area near the bridge provides a spot to pull over, stretch your legs, and take a short walk down to the water for a closer view of the misty falls. This area also serves as a trailhead for more challenging hikes, such as the Mildred Lakes Trail, making it a great base camp for further exploration. The route is typically accessible late spring through fall, though winter weather can bring heavy snow and road closures to these higher elevations. Visitors should pack out all trash, yield to oncoming traffic on narrow sections of the road, and check Olympic National Forest regulations for parking pass requirements, such as the Northwest Forest Pass, at the trailheads.

About 2 miles prior to end of trail, slippery snow. Didn’t go to the end, turned back down. If you have a winch with some extra work you’ll be okay. Self recovery highly recommended. We helped out a few people out there with no gear.
