The Queen
In 1961, the queen visited India for the first time (she has been twice since) and thousands turned out to see her. Times were changing and a royal tour was not solely about processing around grandly anymore. She met with Indira Ghandi, donned diamonds and a tiara for a state event, rode on an elephant in Jaipur, and planted a tree at the Gandhi memorial in New Delhi. She was also gifted with a doll in a turban for her young son Prince Andrew.
King Edward VII
Edward visited when he was the Prince of Wales, traveling around for eight months from 1875 to 1876. Bombay was his main base, but he traveled extensively over the whole country, including to Poona (Pune), Baroda, Goa, and Kerala. He went by train to Madurai, Trichinopoly, Madras, and Calcutta, and by boat down the Ganges to Bankipur, Bihar, Benares, Lucknow, Kanpur, and Delhi.
