A wonderful tunnel that can be entered by crouching. Easily accessible and safe to walk through inside. However, I could not find any historical records of its construction.

The steep path to the quarry has been washed out and is very rocky due to the heavy rain in recent months. Each biker has to decide for themselves whether the stairs at the end of the trail are rideable.
