Take the 2nd stage expressway north past Chaeng Wattana to the very last exit called ‘Western Bangkok Outer Ring Road’.
At the toll gate zero your odometer, follow the sign to ‘Bang Sai’ and turn left.
At 3.1km turn left again onto highway 3309.
At 4.6km turn right into the entrance (three tall Salas) of Piyawan Garden House. Follow the track all the way to the river and park near the restaurant.
The hare also suggests to bring mosquito repellent and consider long sleeves/pants to cover your appendages. Apparently, it is also Mosquito season in Bangkok.
