Halloween 2026: the Terrifying Sea of Sand returns with new features

On Halloween 2026, Mer de Sable transforms into the Terrifying Mer de Sable. For the 10th edition of the event, a host of spine-tingling activities is on the agenda to delight the whole family.

For its ninth edition, the Spooky Mer de Sable makes its way to the Ermenonville amusement park, from October 3 to November 1, 2026. The park in Oise, just 45 minutes from Paris, once again transforms itself to offer Ile-de-France families a memorable Halloween experience.

How to make the most of your Halloween visit?

For the sensitive souls, the park sensibly offers anti-scare stickers available at the welcome desk. These handy passes help keep the creepiest characters at bay, ensuring a visit suitable for younger visitors or anyone who prefers a gentler atmosphere. This thoughtful touch reinforces the park’s family-friendly vocation, where “you don’t have to be tall to be scared.”

The experience is also enhanced by autumnal treats: mulled wine, Pumpkin Latte, and other seasonal delights warm guests between thrills. The themed shops let you extend the experience with keepsakes bearing this edition’s imagery.

The park opens its doors every weekend starting October 3, then daily from October 17 to November 1, 2026 during the Toussaint holidays, from 10:30 a.m. to 6:00 p.m. This expanded schedule provides plenty of chances to experience the event, whether you’re a thrill-seeker or simply curious to discover a tradition that has become a fixture in the Île-de-France cultural landscape.
