Brad, Angelina & Kids Visit French Adventure Park

Days after wrapping filming on her new movie Wanted in Prague, Angelina Jolie, along with Brad Pitt and their family, made a surprise visit to a French amusement park, according to the staff there and the local Charente Libre newspaper.

"We're a small little town, we're not used to having celebrities," said one employee at the Aventure-Parc in Massignac. The facility, located in France's Charente-Limousin region, features tree-climbing, rope swings and other outdoor activities for kids.

"We don't get French celebrities, so it's completely crazy to find yourself standing with Angelina Jolie and Brad Pitt, the most chased-after couple in the world in front of you," said the employee. "Completely crazy."

While the park's six workers were seated at a picnic table having lunch, one told PEOPLE that on Monday afternoon a blacked-out Mercedes van pulled up carrying the Hollywood couple and three of their children, Maddox, 5, Pax-Thien, 3, and Zahara, 2.

"I asked myself, 'Who is this man with a ball cap and this woman with black sunglasses?' " one staffer told PEOPLE. "We were all extremely shocked."

The awed staff offered to waive the standard 5 € entry fee, but Jolie and Pitt insisted on paying. They stayed an hour, using the playground area that included a bouncy castle and a children's obstacle course among other facilities.

"To see Brad Pitt knocking around in a bouncy castle with his children [and] screaming like wild animals was like a hallucination," said park operator Benjamin Gautier.

The three-acre park, which also features rope climbing courses between trees, normally welcomes 100-150 people during the day, but was otherwise empty because of overcast weather, according to staff.
