It extends 37 miles (60 km) eastward into the Caspian Sea, and reaches a maximum width of 19 miles (30 km). Though technically the easternmost extension of the Caucasus Mountains, the landscape is only mildly hilly, a gently undulating plain that ends in a long spit of sand dunes known as Shah Dili, and now declared the Absheron National Park. In this part the peninsula is dissected by ravines and characterized by frequent salt lakes.
