I'm going to be in Brugges and planning on taking a road trip to Dunkirk to see ay WWII sites. Is it worth the trip? Is there much to see/explore/experience?
There is a little museum and a monument about Operation Dynamo near the beach. With low tide the remains of a few shipwrecks are still visible. There are battle field tours, but I didn’t join one, so can’t tell you if it’s worth following.

There are still bunkers of the Atlantikwall spread around. Especially near “Fort des Dunes” at the outskirts of Dunkirk. No idea a visit is included in the tour.
The best preserved part of the Atlantikwall is to find near Ostend.
If it's worth going to Dunkirk depends how much interested you are in Operation Dynamo. Certainly not to miss are the former V2 launch bases La Coupole and Le Blockhaus near Saint-Omer. The huge gun batteries near Cap Griz-Nez too.
