High-energy thrills include sand-yachting on the beach at Boulogne-sur-Mer, where participants aged eight to 88 will learn how to sail along the sands with just a few minutes’ instruction. Younger children are invited to meet penguins, sea-lions, turtles and sharks in the French National Sea Centre, Nausicaä. Families can also put their heads together and design a remote-control car and race it against similar creations made by fellow guests. Catapult-making, an assault course, Easter cookery and egg hunts, evening games, a family disco, and even mini-spa treatments are among the other activities on offer.

The break is based at the three-star Hotel Moulin aux Draps, set in 22 acres of grounds just outside Boulogne. The hotel offers a choice of accommodation – from interconnecting rooms, to doubles, twins, singles and dorms – and holidays are fully inclusive of food, some wine and all activities. 

The Opal Coast Easter Adventure is available 30 March-2 April and 2-5 April 2018, and costs from £249 per adult and £199 per child, including full board, based on families sharing one or two rooms, activities and transfers to Boulogne-sur-Mer.

Meanwhile, the new Opal Coast Family Adventure Holiday is an extended, four-night version of the same break, available in the school summer holidays, 30 July-3 August and 6-10 August 2018. It costs from £329 for adults and £299 for children, on the same basis as above and with a similar mix of activities, but offering extras such as high ropes and a forest ramble, both for the whole family, and a cheese-and-wine voyage for the grown-ups. Plus, there’s a trip to Le Touquet, where there are seven kilometres of golden sands to enjoy and chic boutiques and gourmet food shops to explore.
