The south and south-east part of the district, which lies between Mount Abu and the main spine of the Aravallis, is mountainous and rugged, and is drained by the West Banas River. Abu Road, a station on the main Delhi-Ahmedabad rail line, lies in the valley of the West Banas. Dry deciduous forest is common in this part of the district, and the higher elevations of Mount Abu are covered in conifer forests. Abu Road is the biggest city and the main financial hub of Sirohi District. Sirohi district has the fewest villages in Rajasthan. The portion of the district west and north of Mount Abu is drier, lying in the rain shadow of the mountain, which blocks the southwest monsoon. The southwest corner of the district is drained by the Sukri river, an intermittent stream that drains the western slope of Mount Abu. The northwestern portion of the district is drained by tributaries of the Luni River. The Northwestern thorn scrub forests cover the western and northern portion of the district. Warada is the last village of Sirohi located on Sirohi–Siyana Road. In 2006 the Ministry of Panchayati Raj named Sirohi one of the country's 250 most backward districts (out of a total of 640). It is one of the twelve districts in Rajasthan currently receiving funds from the Backward Regions Grant Fund Programme (BRGF).
