What Travellers Say
Reviews Summary
Visitors consistently praise the Old Caoling Tunnel for its unique cycling experience, comfortable temperature inside, and the stunning coastal views that await at the end. The affordability of bike rentals and the ease of the flat terrain make it accessible for many. Some find the tunnel itself a bit monotonous after a while, and the coastal path can get busy, but overall, it's a highly recommended activity for its blend of history and natural beauty.
"The tunnel is very comfortable for riding a bike. It is built on a mountain slope facing the Pacific, which makes the ride easy but not very challenging. Inside the tunnel, there is always a steady, comfortable wind blowing, and it’s wide enough for 2 e-scooters to pass each other — even wide enough for an ambulance to get through. It seems the tunnel has been approved for emergency vehicles as well. Overall, it’s a lovely riding experience."

"This was a 1st time experience cycling inside the tunnel I really enjoyed it and the tunnel stretches over 2 km with no partition or any sky view, at the end we can see the sea shore"

"Great place for bikers. The tunnel is very very long - flat route inside. The bike rent is very reasonable for the price and time of use. Worth it! Scenic view outside the end of the tunnel. It was pouring hard when we visited, but still had fun!"
