Since you're self-sufficient in a campervan, I personally don't need a sanitary block. The water and waste disposal facilities are fine, the pitches are large, but the access to the free pitches (unfortunately, as already mentioned, not signposted) is very narrow and the trees hang low. Very quiet at night. You're used to something different from a campground. Perfectly fine for two nights. The place is very quiet, and a bike tour is okay.

Quiet location, large pitches, sanitary facilities on the campsite can be used, ideal for visiting the city, 4.8 km to the Cathedral.

Quiet spot on the cliff, police check tickets twice a day, waste disposal available

It's a nice spot in principle, if it weren't so narrow that your rear wheel is already at the curb and your front wheel is half in the road. Newly arriving motorhomes then have difficulty getting past because there's also a high curb separating the bike path. It's stated that vehicles up to 7.50m in length can park there. The exit is very narrow, and you'd have to drive back to empty your waste tank. It's ideal for small vans.

Good alternative spot for visiting Étretat, 2 water/electricity hookups, free water. Take bus line 21 for €1.80 per person to the Le Grandval bus station. It runs hourly. It's 6 km by bike, but there's no bike path! The parking area is quiet, despite the nearby road. The only downside was the rooster nearby, who decided to crow even at night 🙉 The parking area in Étretat was total chaos; the campsite behind it was also completely full by 1 p.m. ...

Quiet, good waste disposal, poor Wi-Fi at our site, waste disposal before the barrier, water only available with a CCP card. Wonderful for visiting Calais.

Located directly on the road, it's a bit noisy as a result. Entry is possible without the app. Set the language, pay with Visa, print your ticket and hold it against the barrier control panel. Exit with the same ticket and a QR code. Water and electricity are only available via the app.

Quiet spot, a few upper pitches including electricity. The lower, sloping pitches flood when it rains. Upon entry, your license plate is scanned, then you choose one of the many available spaces. Upon exiting, you pay at the machine by entering your license plate number. The barrier then opens again.

It fills up quickly. Parking spaces are shown on a map at the entrance, but unfortunately, these are often inaccessible in the rain. Motorhomes park wherever they can find a spot. Even if three spaces are shown as available, finding one can be challenging, as some vehicles leave a lot of space between them. There are also many potholes. Okay for one night while visiting Le Tréports.
