My faith in Laos buses was restored when lo and behold, the 10pm night bus did appear - and even slightly early. Our travel agent friend had a colleague on the bus who gave us a heads up 40 min before it was due, and there were thankfully seats available too. Massive win.
The journey was fairly bumpy and took many a twist and turn, but, despite the best efforts of a Laos crooner and his keyboard blasting through the airwaves, we actually got a decent amount of sleep on the 12 hour journey (which actually took 12 hours too!).
However, when we saw this as a chance to complete our intended itinerary of a trip to the Vieng Xai caves, supposedly a mere 50min and 10,000kip (<£1) journey from Sam Neua, the detailed info from the lonely planet, wiki travel and various blogs started to deviate from the reality.
Supposedly the buses leave "regularly" from the local bus station, or at least at certain given times. We hoped in an overpriced tuktuk to get there in time, only to be told by the driver the buses were finished for the day and he would take us for 250,000kip (£20+). Armed with internet knowledge as we were, we dismissed his offer. And waited...
After an hour, a lady appeared behind the counter to say there was no 11am, next bus at 1pm. With 1h30 to wait we approached the tuktuks, and were offered 250,000kip best price. We declined (our kip funds were carefully budgeted for our last 24hrs in the country so we're pretty tight). We waited...
At 1.15 our lady reappears to dismissively inform us that the bus wasn't coming. Needless to say, we were kind of expecting this, so after a little deliberation, we decided we ought to bite the bullet and head out to the caves with our overpriced tuktuk.
And, well, a worthwhile decision that turned out to be. The caves were the base and hideout of the Pathet Lao, the communist independence movement, during the 9 years of bombing by the USA in the 1960s and 70s as part of their attempts to block communist spread in Asia. Assisted by the communists in Vietnam in training, supplies and shared ideology, the politburo and the locals lived, planned and survived by building their homes in the caves (there was even a theatre/cinema hall in one cave complex) under daily assault from the air. Two million tonnes of bombs were dropped, with 30% failing to detonate - many areas in the mountains are still littered with them, and at current rate of clearance they think it will take 100 years to make the country safe.
Though it was certainly more complicated and costly than we'd anticipated, it would have been a shame to let a few transport misadventures deter us from our destination. It was a real insight into the beleaguered past of the country and one that puts a few long waits for non existent buses into perspective.
