Ferry ports are usually getaway places but Rupert Parker decides to cover the 50km between these two French towns on foot, following the English Channel

I’ve always thought that this part of France deserves further investigation but in the past I’ve always been on the way to somewhere else. Yet it pays to linger and the Côte d’Opale, or Opal Coast, stretches west from Calais along the English Channel, with its characteristic interplay of grey and blue, between sky and the sea. It promises windswept beaches, giant sand dunes, steep cliffs and quaint seaside resorts.

I arrive in Calais via Eurostar on a bright sunny afternoon and enjoy a night on the town before two days of intensive walking. Fresh fish is on the menu here so I opt for the Brasserie de la Mer and am not disappointed. Next day, the weather is set fair and as I make my way to the beach I’m surprised to find it almost deserted, just a couple of dog walkers.

In the distance are the white cliffs of Dover, the silence broken by car ferries chugging their way to and fro. The tide is out so I’m able to walk by the sea, on firm sand, passing numerous break waters. Ruined remains of WW2 bunkers and gun emplacements are reminders that this was once part of Hitler’s Atlantic Wall, built to prevent an allied invasion. After an hour, I reach Sangatte’s large radar mast, and leave the beach to walk on a surfaced track on top of the newly renovated sea wall.

By now there are lots of people enjoying the morning sunshine, but I’m soon back on my own as I head off upwards into the countryside. I’m aiming for Cap Blanc-Nez, the highest point around, although only a measly 120m high. It’s marked by a grey obelisk, built in 1922 as a memorial to the WW1 Calais squadron who patrolled the Channel.

The views across the sea to the Kent cliffs are stunning, and the place is a magnet for day trippers. It’s a bit of a shock to find so many people and the car park is heaving. Fortunately, as I follow the path, I leave the crowds behind, passing more WW2 bunkers before descending to the beach. I can now make out the holiday resort of Wissant in the near distance and the other high point, Cap Gris Nez, far behind it.

It’s about another hour along the beach and I dodge kite surfers and wade shallow rivers before arriving at my destination. Children are frolicking in the waves and the village is in full-blown holiday mode. Restaurants on the sea front promise moules frite and platters of fruits de mer, but I settle for a beer to celebrate the end of my five hours of hiking.

Next day, it’s another glorious morning and I set off early as I’ve more ground to cover today. My feet are slightly sore so I walk along the sand in bare feet, letting the salt salve my blisters. Hardy joggers and a couple of swimmers are my only companions and at the water’s edge tractors are buzzing around the mussel poles.

I’m aiming for Cap Gris-Nez so after an hour, leave the beach at La Sirène, climbing upwards through wild flowers towards the lighthouse. It’s visible for miles around and is an essential beacon for Channel shipping. During WW2 this area was heavily fortified and I pass German bunkers as I follow the track down to sea level.

When I reach the shore, the track stays on the land, but there’s still three hours before high tide so I prefer to walk on the beach. It’s slightly tricky as there are rocks and boulders to negotiate before I reach the small fishing village of Audresselles. The seafood restaurants are tempting me but I press on, walking on the pebbles.

Ambleteuse has an impressive Vauban fort, built in 1680 to guard the estuary of the River Slack. It’s only accessible at low tide and the path diverts inland but I’m able to wade across the channel with the shoes in my pack. Still more beach walking before climbing across a headland on a sandy track. I drop down back to sea level and reach Wimereux, with its busy promenade complete with big wheel, and stop for an ice cream.

I’m now on the home stretch and the path leads away from the coast before passing through sand dunes to the Pointe de la Crèche. Steep steps lead upwards and I traverse car parks full of camper vans, as I carry on along the cliff. Finally I drop down to sea level and reach the beach at Boulogne, packed with wind surfers and swimmers. There’s just time to visit Nausicaä, the largest aquarium in Europe, before I celebrate the end of my hike with an excellent dinner at La Matelote.

It’s been an enjoyable two days but I feel I’m just getting started. The trail I’ve followed between Calais and Boulogne is part of the longer GR120, also known as the GR du Littoral, which runs 285km from the Belgium Border to Mer-les-Bains on the edge of Normandy. That’s next time’s challenge.
