We decided to go back to Hanoi and catch the overnight train to Hue. This time a hard sleeper, and hard it was. The only thing between me and the bunk was a carpet and a sheet. Surprisingly we slept quite well. Toilets and sinks were cleaner than expected and better than many I have used.
The next day we visited the Demiliterised Zone (DMZ) on a tour. It set off at 6am for 12 hours stopping only to briefly walk around or eat. Very interesting walking down Vietnamese underground tunnels at Vin Moch which were built and lived in during the war by both the local farmers and the Viet Com.
So today we moved on from Hue to Hoi An by bus. Still it continues to rain.
