Gopal Lal Ji Maharaj Ka Mandir is a Krishna and Radha temple near Hanumantal, Jabalpur's large old tank. It is associated with the Pushti Marg tradition and is a more specific religious stop than a casual lakeside wander.
Pair it with Hanumantal Lake and the nearby Jain temple area. The setting is local and lived-in, so it works best if you are already exploring this part of the city.
