The 3 most visited cities in the country’s north-west- Delhi, Agra and Jaipur are what make THE GOLDEN TRIANGLE. ‘Golden’ in the name suggests that all the three cities bid stupendous prosperity and offer to visitors an enriching experience to discover India’s cultural and historical finery. The reason behind using the word triangle is that these destinations form a near equilateral triangle on the map, which is around 200-250 km along each side.
