Mysore Palace Lighting timings:
Sundays & Public Holidays :7pm-7.45pm
Mysore Palace visiting hours is everyday from 10 am to 5.30 pm. There is no weekly off for Mysore Palace!
To see the Mysore palace illumination no ticket is to be bought. Arrive a little early to settle at a vantage position. The charm is to be there when the palace is lit in one stroke, rather that arriving after the illumination is already on. For both daytime visiting and illumination, entry is through the southern gateway.
Also note that during the Mysore Dussehra festive days, the illumination is done on all the days, for extended hours.
Also note, the lighting would be cancelled if the state declared mourning on account of events such as demise of important personalities.
