ISB is in a housing development in Nonthaburi province's Pak Kret District, a northern suburb of the Bangkok metropolis.

To reach there by car/taxi from central Bangkok (approx 45 mins), use the second stage expressway north to the Chaeng Wattana exit (follow signs to Pak Kret). Turn left into Chaeng Wattana Road and go on for 2 kilometres. Turn left off Chaeng Wattana Road

at the flyover (just before Big C/HomePro supercentre) onto the Pak Kret bypass. Travel 1.5 kilometres to the end of the bypass

and turn left into Samakee Road. After another 500 metres, turn left into Nichada Thani (big sign). Just after the sharp bend right (past 7/11 shop), turn left into Nichada Thani housing development. ISB is 300 metres from the entrance barrier. You will need one photo I.D. for Nichada Thani and another to enter the school itself. (Taxis do not need your ID and cannot enter the school.)
