The tunnel is about 1 km long and without light. Short of the northern exit is a kink, so that its incidence of light is only relatively late visible. We went this way without a flashlight. A very interesting experience.

The Suonen tunnel is 1.6 km long and not illuminated. An interesting cool experience! Highly recommended!
