The Mecca of all the lovers, without places to go and extra money to spend in Delhi, is the beautiful and serene Lodi Garden. It was designed over two dynasties–the Sayyids and Lodis (15-16th century)–to be a sort of everyone-take-one graveyard for their families. During the British times the garden went under the moniker of Lady Willingdon Park, all that stopped with the Independence when they reverted back to being good old Lodi garden. In 1968, the gardens were spruced and relandscaped by JA Stein and Garrett Eckbo. There are several tombs in this area. You can climb to the top of some of them.
