The range is an extension of the much larger
Luberon range. Although it is not high – some 498 m (1,634 ft) at its highest point – the Alpilles range stands out impressively, as it rises abruptly from the
Rhône valley and from the very flat alluvial plain of
Crau. The range is about 25 km long by about 8 to 10 km wide, running in an east–west direction between the Rhône and
Durance rivers. The landscape of the Alpilles is one of arid
limestone peaks separated by dry valleys. ==Communes==
