The graveyard was immense; about 16,000 allied soldiers died (also about 90,000 asian laborers); 6,982 soldiers are buried here. It is well maintained - there were sprinklers in one section and a worker was trimming the grass. We didn't go into the museum.
After this visit we continued by bus to lunch and then to a spot on the river for recreation, We rode up river in a longboat and then got on a pair of linked bamboo rafts to float back to where we had boarded.
