Is the Opal Coast a good family destination? In one sentence: yes — it's one of the most child-friendly coasts in northern Europe, with Europe's largest aquarium (Nausicaá), lifeguarded sandy beaches, seals to watch and a cost far below the southern resorts. All on a compact stretch where everything is a day trip away.
We welcome families year-round in our Le Portel mobile homes, and this guide gathers what really works with children — activities by age, the safest beaches, and how to keep spirits up on a rainy Channel day.
Why the Opal Coast for a family holiday?
Three things set it apart for a stay with children. Variety: a giant aquarium, beaches, cliffs, seals, farms and historic towns, all within 45 minutes of each other. Safety: family beaches lifeguarded in season, and a generally calm setting. Budget: accommodation, dining and activities are noticeably cheaper than on the Atlantic or Mediterranean coast.
From a central base like Le Portel, you adapt the plan to the weather and the children's mood day by day — a real comfort with a family. Our coast road-trip itinerary shows how to string days together without tiring out the little ones.
The must-do activities with children
Our pick, tested and approved by the families we host:
- Nausicaá (Boulogne, 10 min): Europe's largest aquarium, a full day — sharks, sea lions, the huge open-ocean tank. The must-see, detailed in our Nausicaá guide.
- Seal watching in Authie or Somme bay: magical for children, on the falling tide with binoculars (see our tides & seals guide).
- Foraging on the foreshore: crabs, shrimp and shellfish — the free activity kids love.
- Sand-yachting on the big beaches (Hardelot, Le Touquet): thrills from around age 8, supervised by clubs.
- Petting farms and parks in the hinterland, perfect for the youngest.
The safest beaches for children
Not all beaches are equal with young children. Favour lifeguarded and partly sheltered beaches: Le Portel (sandy at low tide, below our cliff), Wimereux, Hardelot (vast and family-friendly). Always check the swimming flags and the tide times — on this coast the sea goes out far and comes back fast.
Hosts' tip: at high tide some beaches shrink a lot; aim for the falling tide for space and warm pools where children can paddle safely.
A rainy day? Don't panic
The sky changes fast over the Channel. Keep these indoor options in reserve: Nausicaá (a full day under cover), Boulogne's fortified old town and castle-museum, Maréis in Étaples (the fisherman's trade, hands-on), and the region's museums. And from a covered terrace, watching a shower pass over the sea keeps children busier than you'd think.
Where to stay as a family on the Opal Coast?
For a family, the seaside-campsite mobile home ticks every box: separate bedrooms (put the children to bed early and enjoy the evening), a full kitchen (skip eating out every meal), a terrace, a secure setting and a controlled budget. Our Blueportel Prestige sleeps up to 6 (3 bedrooms), the Horizon up to 4.
Expect €80-140 a night depending on the season, with no fees when booking direct — far less than a family hotel. Availability and rates are online; to compare every option, see our accommodation comparison.
Stay facing the sea in Le Portel
Blueportel offers two fully equipped mobile homes at Le Phare d'Opale campsite, on the clifftop of Le Portel: panoramic sea view, covered terrace, 10 minutes from Nausicaá and at the heart of the Opal Coast.
Frequently asked questions
Is the Opal Coast suitable for young children?
Yes. Sandy beaches lifeguarded in season and partly sheltered, Nausicaá, seals, foraging and petting farms make it an ideal destination from the youngest age. Remember to check the swimming flags and tide times.
What family activities are there on the Opal Coast?
Nausicaá (Europe's largest aquarium), seal watching in Authie or Somme bay, foraging on the foreshore, sand-yachting on the big beaches, and petting farms in the hinterland for the youngest.
What can you do with children when it rains?
Nausicaá for a full day under cover, Boulogne's old town and castle-museum, Maréis in Étaples, and the region's museums. A covered terrace facing the sea also lets you enjoy the show while staying dry.
How much does a family holiday on the Opal Coast cost?
Much less than the Atlantic or Mediterranean coast. A sea-view mobile home for 4-6 people costs €80-140 a night booking direct, and cooking some meals greatly cuts the dining budget.
When is the best time to come as a family?
July-August for peak beach season and lifeguarded beaches, June and September for the best weather-to-crowds-to-price ratio, and off-season school holidays for Nausicaá and spectacular storms at reduced rates.
