It is a very beautiful park with magnificent fountain & museum of natural history not far from Marseille main railway station. When I visited it in July the fountain didn’t work because of the cleaning work, but still the structure looked amazing. The park is accessible for wheelchairs, but only the lower part of it since the are stairs to climb the fountain and to visit back side of the park with children’s playground, small cafe with snacks & ice-cream. Wonderful view over Marseille is seen from the top of the fountain till Notre Dame de la Garde & far more. It is also pets friendly, but don’t forget to take a small cleaning bag for your small friend. I personally enjoyed the architectural construction and the city view, it is veeeery impressive!
