September on the Emerald Coast: a light like no other
There’s something special about a September vacation in Northern Brittany. The sea air remains mild, the Côtes d’Armor regains its serenity, and the landscapes take on a hue that summer doesn’t offer. The GR34 trails can be explored without the crowds, the Bay of Fresnaye can be admired in the silence of calm mornings, and the sand on the beaches of Saint-Cast feels vast once again.
That’s exactly what we offer: the tranquility of a low-season stay, without compromising on comfort or the quality of your experience at Le Châtelet.
The water park, the beach, the sea
Our heated pool area remains open in September, so you can enjoy the water no matter the weather. As for the beach, it’s just a short walk from the campground —about a hundred steps down, and you’re there. You’ll appreciate this rare privilege: having the beach right at your doorstep, without having to share the path with hundreds of other vacationers.
From the panoramic bar, the view of the bay is one of the most beautiful you’ll find along this coastline. Imagine enjoying your morning coffee overlooking the Atlantic, bathed in the slanting September sunlight.
For water sports enthusiasts, bike and paddleboard rentals are available at the campground—great ways to explore the bay at your own pace.
