5 /5 Darius Vlad: You have to pay a entrance fee to get inside.
But after you get in you have beautiful beaches and sand dunes up until you reach the fort.
There will be a self guided tour, you can walk almost everywhere you want had have amazing sights and tunnels to explore (be aware that mose are dead ends and youll need to follow your steps back) but nonetheless the historical place is amazing to visit.
