Practical notes
entry is free and the open monument is accessible daily in daylight — the interior passages are dim and maze-like, so carry a phone torch, wear sturdy shoes, and avoid visiting alone late in the day. Nearest metro: Qutub Minar or Saket. Allow about 30 to 45 minutes, easily combined with the Qutub complex, Zafar Mahal and Mehrauli Archaeological Park nearby. It is one of the most rewarding stops on a Mehrauli heritage walk — both for its architecture and for the sheer strangeness of finding your way through its passages.
