Audio Guide of the Maisy Battery Museum

The site is generally open every day from April to September, from 10:00 AM to 5:00 PM (last admission). It is located on Route des Lits in Grandcamp-Maisy, and you can check the exact opening dates on its official website before you go.

It is not free; general adult admission is around €12, with reduced rates for children, students, and veterans. Considering it is a privately owned and independently maintained site that offers access to miles of real trenches, the price is very reasonable.

I recommend allowing between 1 hour and 1 hour 30 minutes for the full visit. The site is extensive, with nearly 3 kilometers of original trenches and several bunkers to explore, so you will want enough time not to miss any details.

Its history is fascinating because it was 'forgotten' and buried for 60 years until historian Gary Sterne found it using an old map. Unlike more polished sites, here you will see guns and command posts in a raw and authentic state of preservation.

Spring and summer are ideal to avoid excessive mud in the trenches, preferably on a dry day. If you go first thing in the morning (10:00 AM), you will avoid large groups and enjoy the historic atmosphere more peacefully.

Due to the historic nature of the terrain, which includes narrow earthen trenches, uneven ground, and underground bunkers, access is very difficult for wheelchairs. Walking on uneven terrain is required, so it is not the most accessible attraction in the area.

You are in a strategic location, just a few minutes' drive from the famous Pointe du Hoc, captured by the Rangers. You are also close to Omaha Beach and the American Cemetery at Colleville-sur-Mer.

Wear comfortable, sturdy shoes that you do not mind getting dirty, as you will be walking on dirt and grass. Also, because this is a site with so much hidden history, using an audio guide or carefully reading the brochures is crucial to understanding the strategic importance of what you are seeing.
