Hamma Hamma Falls is a 75-foot two-tier plunge on the Hamma Hamma River in Olympic National Forest, viewed from a concrete bridge over the gorge near the Mildred Lakes Trailhead. The drive is the obstacle: 13.3 miles of Forest Service road off US-101 (the back half is rough). Once parked, the falls are right there — no hike. Pair with the Lena Lake Trail nearby for a longer day.

0 miles each way, rated easy. Mildred Lakes Trailhead lot at the end of FR 25. Free.
