According to Hike Tri-Cities, the McNary Dam Tunnel Hike begins in Plymouth and runs about 5 miles along the Columbia River to McNary Dam. It’s considered a moderate to easy trip and suitable for most hiking levels. Small children could have difficulty inside the abandoned railroad tunnel. It gets dark, can be wet with standing water, and rocky. Bring a flashlight for sure – although the tunnel is less than a quarter mile, it curves in the middle which blocks out light for a brief time. In the summer months, beware of rattlesnakes.
