Not far from the Castellan hotel, the Étang de l'Olivier is a little jewel of nature that embraces the city centre of Istres. It covers more than 220 hectares and is linked to the famous Etang de Berre.

It is also on its banks that life in Istres comes alive and is organised: starry Thursdays, the national festival and also the Dinausaur'Istres park.

The Étang de l'Olivier is also a wonderful panorama for your walks, alone or accompanied, thanks to its pedestrian ring road. You can observe the local fauna and flora, as well as the fishermen who venture out onto the water in search of fresh catches, carp, roach or even perch and pike.

Thanks to its proximity to the city, the watering hole is busy all year round.
