Tunnel Beach is located near the tiny town of Oceanside on the Oregon coast. It gets its name from a century old walking tunnel through a rocky outcropping. The tunnel is unlit and strewn with large rocks and, occasionally, logs that have been deposited by high surf. The better plan is to wait for a low tide and walk around the outcropping ... which is what we usually do.
A short video (02:45 in diration) captured at the same location has been posted on my YouTube channel at the following link:
