The Hammond Trail is a 5.5-mile stretch of the California Coastal Trail that winds through Humboldt County from the Arcata Bottoms north to Clam Beach County Park near McKinleyville. What makes this particular segment special is its history—the trail was built along abandoned railroad properties, specifically the old Little River and Hammond Railroad line that once ran from Humboldt Bay all the way up to Crannell. You’re literally walking where trains used to pass, which adds a layer of character to the experience.

It took decades to get this done. Planning and environmental studies started in the 1970s, and the final segment wasn’t completed until 2001, partly because much of the route had to be constructed across private property. Despite that complexity, the trail exists now as a multi-use path that welcomes leashed dogs.

The terrain isn’t flat—it undulates along the Northern California coastline, so expect elevation changes as you go. That also means you get better views as you move through the landscape. The combination of coastal vistas, the sense of walking through historical ground, and having your dog with you makes this a genuinely interesting outing, not just another beach walk.

To get there from Arcata, head north on Highway 101 and take the Giuntoli Lane exit, which is about 2 miles north of town. Turn west onto Janes Road and follow the signs toward Mad River Beach. You’ll park at the pedestrian bridge, which serves as the main trailhead access point. Dogs need to stay leashed, but they’ll have plenty to sniff and explore as you make your way along the trail. The route gives you options for how long you want to spend out there—you can do the full 5.5 miles or turn around whenever you and your dog have had enough.
