Family weekend in Boulogne-sur-Mer: the 48-hour plan our guests swear by

Friday evening: the smart arrival

If you can, arrive on Friday evening rather than Saturday morning: you gain an evening and, crucially, the Nausicaá opening slot on Saturday. From the UK, an after-work tunnel crossing puts you on the coast by 8pm French time; from Paris, leaving at 6:30pm gets you here by 9pm. Settle in, and if the children are still standing, walk down to see the sea at night from the Le Portel promenade — the lighthouse sweep and the ferry lights in the strait never fail.

Logistics: do your basic shopping before arriving or at the Le Portel supermarket (open until 7:30pm). In our mobile homes, the full kitchen covers breakfasts and a simple dinner — the real luxury of a family weekend is mornings without a hotel timetable.

Saturday morning: Nausicaá at opening

The heart of the weekend. Be outside Nausicaá at 9:15am for the 9:30 opening, with dated tickets booked online (cheaper, fast lane). Head straight for the giant high-seas tank: for the first half-hour you'll have the 20-metre window and its manta rays almost to yourselves — the memory the children will tell school about. Continue along the 'Journey on the High Seas' trail, then the touch pool before the midday rush.

Allow 3 hours for this first pass with children aged 4-12. Our complete Nausicaá guide details the optimal route, the must-see animations (sea lion feeding!) and the crowd traps. Practical note: the official car park fills by 11am — another argument for the morning slot.

Lunch: in fine weather, picnic on Boulogne beach right outside the aquarium; otherwise a seafront friterie-brasserie (moules-frites, local fish and chips) or the Nausicaá restaurant overlooking the giant tank (book when you arrive).

Saturday afternoon: the old town as a castle

Fifteen minutes' walk from the port (or 5 by car, ramparts car park), Boulogne's walled old town is best visited as a treasure hunt. The full circuit of the ramparts is 1.5 km on foot, car-free, with turrets, fortified gates and plunging views: children run ahead, parents follow. The tourist office offers activity booklets for 6-12 year olds — pick them up on Place de la Résistance.

Two short visits that always please: the crypt of Notre-Dame basilica (the largest in France, 1,400 m² of underground passages — guaranteed Indiana Jones atmosphere) and the castle-museum with its Egyptian mummies and Inuit masks, two safe bets in any weather. Between the two, snack time on Rue de Lille: vergeoise-filled waffles, chocolatiers, and the cheesemonger who'll (mischievously) let you smell Vieux-Boulogne, the world's smelliest cheese.

Dinner: a 'welsh' by the port for the full local experience — cheddar melted in beer, grilled over bread and ham, with chips. Child version: fish and chips or moules-frites. Back to Le Portel for the sunset from the terrace: in June-July the sun drops into the Channel around 10pm, right in front of the mobile homes.

Sunday morning: beach, Fort de l'Heurt and sand yachting

Sunday belongs to the sea. Check the tide times the night before: if low tide falls in the morning, head down to Le Portel beach for rockpooling (shrimp, crabs — net and bucket, the favourite activity of under-10s) and walk out to the Fort de l'Heurt, the 1804 Napoleonic fort only reachable at low tide. The 'bâches' — warm lagoons left by the sea — serve as natural paddling pools from late spring.

If the tide is high, swap with the Sunday-afternoon option, or go for the coast's signature activity: an introduction to sand yachting (from age 8, 1.5-2 hour sessions run by the Le Portel or Hardelot clubs — book the week before). Guaranteed thrills and memorable photos — it's the activity our guests mention most in their thank-you messages.

For families with toddlers who prefer gentler pleasures: the Le Portel promenade by scooter, the campsite playground, and a hot chocolate facing the sea.

Sunday afternoon: capes, Wimereux or Équihen before the road

Before heading home (Sunday returns are smooth on the A16 until about 5:30pm, and tunnel queues stay light before 6pm), three possible finales depending on remaining energy:

• The big show — Cap Gris-Nez (25 min): an hour's walk on the cape path, England on the horizon and the ballet of cargo ships in the world's busiest strait. Crêpes in Audresselles on the way back.
• The gentle one — Wimereux (15 min): a stroll along the Belle Époque promenade among pastel villas, Italian ice cream, and a lifeguarded swim in season.
• The wild one — Équihen-Plage via the clifftop path (on foot from the campsite): 1.5 hours there and back above the sea to the famous upturned-boat houses.

Plan B: the rainy-day programme

Channel weather changes fast — it's what creates the 'opal' light — but a wet weekend is still a great weekend with the right plan B. Nausicaá happily absorbs 5 dry hours (save it for the wettest day). The basilica crypt and the castle-museum add 2 covered hours in the old town.

Beyond that: Aqualud at Le Touquet (indoor water park, 30 minutes), the Lace and Fashion Museum in Calais (surprisingly fun, working Jacquard looms, 30 minutes), the Atlantic Wall museum in the Todt battery (ages 8+), or Boulogne's bowling alley as a last resort. And the option that never disappoints: a board-games afternoon in the mobile home, hot snacks, rain on the bay window and the sea in cinemascope — our winter guests come precisely for that.

The real weekend budget for a family of 4

Here's the observed budget for two nights and two days, for two adults and two children, at 2026 prices:

Logistics: getting here, staying, organising

Getting here: A16 exit 31 (Boulogne) or 28 (Le Portel); 2.5 hours from Paris, 1.5 from Lille, 2 from Brussels, 50 minutes from the Eurotunnel terminal — we regularly host English families on a first hop into France. By train: TGV or TER to Boulogne-Ville via Lille or Amiens, then taxi/bus; a car remains the practical option for exploring.

Staying: a town-centre hotel works for one dry night, but the family experience improves enormously with somewhere to breathe: a kitchen for timetable-free breakfasts, a terrace for the apéritif while the children play, separate bedrooms so the little ones sleep at 8:30pm without whispering in the dark. That's the whole point of our mobile home vs hotel vs Airbnb comparison. Our two mobile homes, Prestige (3 bedrooms, sleeps 6) and Horizon (sleeps 4), tick those boxes with the bonus of panoramic sea views from the clifftop of Le Phare d'Opale campsite.

Organising: book Nausicaá online as soon as your dates are set (and sand yachting a week ahead in season); check the tide times to slot in the beach and the Fort de l'Heurt; pack windbreakers, boots for rockpooling and a kite — the coastal wind deserves it. To stretch the weekend into a longer stay, our complete Opal Coast guide takes over with 4- and 7-day itineraries.
