I wish the guide was more interested in the tour he gives us. Sorry I was disappointed. Expected more stories historie than facts I could read on the panels.

It's nice, but it's COLD. Make sure to pack an extra jacket or a sweater. Do not underestimate it, it's like being in a really big freezer. The tour is quite nice though, it's really in depth! There are some stairs which you need to conquer but I think they also have a wheelchair accessible route! Would recommend.

Well preserved bunker with many exhibits and details. Unfortunately the guide spoke only French, so we didn't receive enough information. Maybe audioguides or signs in english could save the situation. The excursion is long, be ready to walk a lot, as well as cold temperature inside all year around, so better to take a coat.

From the people running the visitor centre to the guys conducting the tour, it was excellent. The walk up to the entrance is quite arduous for us oldies and then you have to walk down wet stairs, to get to the tunnels. The tour takes quite a while and is a fair bit of walking. Loud noises abound as some of the ventilation and engines still work, and they are demonstrated! Super interesting, a unique experience. The English tour was at 1500, French and German language tours are also available.

Very interesting and well presented by the staff.

Amazing glimpse into the Magniot Line fortifications - the bunker system is incredibly well preserved and huge in scope! The 3 hour tour is great value at 12 euros, although if you want it in English you have to book ahead (I jumped on a German tour but knowing some WW2 background helped me understand most of it through context). Bring something to keep you or kids warm as it's about 9 Celsius in the bunker and you quickly chill! Info in English is essentially nonexistent, but to see some of the above-ground structures and tank/infantry defences you'll need to follow the red and green trails (no charge). I just drove slightly north and parked on the E85 road which has easier access - you can't miss the tank defences! All-in-all a great attraction and great value - I highly recommended the tour.

Amazing.
