다넨‬에서 가장 멋진 ‪14‬개의 천연기념물

From the big track gravel, other side very nice path to vennbahn. Second way is recommended.

The Vennbahn border tunnel between Belgium and Luxembourg is closed to protect the winter quarters of rare bat species. The path to the tunnel is beautifully designed with bat information boards. The detour of about a kilometer there (and back) on the Belgian side to the gate at the tunnel entrance is worth it. Shortly before the tunnel entrance it suddenly becomes quite cold.

We can't really recommend it. You drive about 1 km off the main path and then end up in front of a gate in front of the tunnel, which is closed. You can save yourself the detour.

Definitely worth going back and forth on this bat learning trail. Beautiful to see how nature takes this back. And educational.

Accessible from one side with a racing bike. The other side is off-road (doable, but risk of puncture)

Terrific climate in summer at over 30 °. On the way there in the cool, cooling down is guaranteed. A dream. You have to experience it.

The tunnel is closed, but this natural experience is worth seeing. The drive through is worth it.

What a great way. A detour is worth it, even if you can't get through the tunnel.
