Created in the 1920s, River Oaks, which includes several loops of Buffalo Bayou, remains Houston's ultra-chic and exclusive residential district. At the time, its residents came here in search of a little freshness to escape the stifling summers. The huge mansions with galleries, typical of the southern United States, can be appreciated all the more in spring, when they open their doors for the Azalea Trail. The Memorial Park, a vast oasis of greenery, completes this elegant picture.
