This temple site is included in the itinerary of most pre-booked tours to the Cu Chi tunnels. He temple itself is an impressive building set in extensive grounds and unlike anything else you are likely to see in the guise of religion. The internal design of the temple is a truly amazing array of colour and we went there for the midday service to see the very colourful monks and nuns conduct themselves in the main prayer area whilst the tourists are welcome to view from the gallery above.
Interesting though it is, putting it into the same itinerary as Cu Chi is a bad idea – My Son is best viewed at lunchtime which means you will have a mad dash around the Cu Chi site either first thing in the morning or before it shuts in the afternoon.
