After the exit from Lal Quila metro station, the first temple you reach is Shri Digambar Jain Lal Mandir Ji, and then Shri Gauri Shankar temple – both on the left-hand side. Walk further a little and you will reach Esplanade Road (cycle market) again on the left-hand side.
Enter the Esplanade Road and walk straight till you reach Shahi Jama Masjid on the right-hand side.
