There are four tunnels, the smaller ones a few hundred meters long, the longest about 2.8 km! It was pitch black (yes, I had my bike lights on), wet, and dripping from the ceiling. I found it totally creepy and wouldn't go through it alone again.

The tunnel is closed. Carrying your bike over the scree is the only option, but it's very challenging.

Here the asphalt road ends and you can no longer continue on the BDC.

Cycled it today. It feels like it is not maintained and starts to be overgrown. Also, when turning from the road after the roundabout, you will have to cross a closed barrier.
