Carrying rainbow-coloured flags, the demonstrators marched to the beat of traditional Indian drums, calling for equal rights for them in the country.
The parade culminated at Jantar Mantar, where the demonstrators distributed rainbow-coloured flags and badges among the members of the public.
In 2009, Delhi High Court had decriminalised gay sex, which until then had been punishable by up to 10 years in prison.
The provision remains intact as far as it applies to non- consensual gay sex and intercourse with minors.
A stay against the high court verdict was sought from Supreme Court, which did not grant the request.
The apex court, thereafter, on March 27, 2012, reserved its verdict on a number of appeals which have challenged the high court verdict.
