We had one day in Ho Chi Minh. The port is quite close to town. We booked a trip to the Cu Chi tunnels for the day which was great. It was a good way to get out of the actual city and see the countryside. The traffic was unbelievable with bikes, cars, and motorbikes everywhere. The countryside is beautiful. There was a torrential downpour in the afternoon and so the city sightseeing had to be abandoned. However, i would like to go back there to experience some more of this interesting city.
