The National Capital Territory of Delhi is a union territory containing India's national capital and a dense collection of historic settlements, planned districts and modern neighbourhoods. The Yamuna River and the rocky Delhi Ridge shape its geography, while monuments, museums, religious sites, markets and government institutions reflect its long role as a political and cultural centre.
Travellers commonly divide a visit between Old Delhi, the monumental core of New Delhi and the archaeological landscapes of south Delhi. Metro services make cross-city travel practical, although first- and last-mile transport is often required. Summer heat, the monsoon and winter air conditions can materially affect an itinerary, so check current forecasts, public guidance and attraction schedules before travelling.
