Day 1: Luang Prabang to Vang Vieng – 200 km

We start our tour by leaving Luang Prang and heading south through twisting terrain to Xaing Ngeun and up into the mountains up to the Kasi Pass. From there it’s down to our day’s destination, Vang Vieng, passing LS25 near Kasi and the old runway LS16 in Vang Vieng, where we stay overnight. Vang Vieng is a fun place and great for our first night’s stop.

Day 2: Vang Vieng to Long Tieng – 150 km

Today is a big day with a lot of ‘off road’. A journey that takes us climbing up and around the Nam Gnon Lakes. Reaching those lakes gives us some great not to be missed views of the surrounding countryside. Then we hit the new road and ride down into Long Tieng. Long Tieng was a military base which during the Laotian Civil War, served as a town and airbase operated by America’s Central Intelligence Agency.

The airbase site was known as Lima Site 20A. It is that site that we’ll be at the very center of somewhere hugely significant! It has been called the ‘most secret place on Earth‘ and played a pivotal part during the War. We will visit General Vang Pao’s House along with the Kings Place, Skyline Ridge, the Runway, and for the fit amongst us, we can climb the speed brake. We’ll see some of it today and the remainder tomorrow morning. We overnight stay at a local guesthouse.

Day3: Long Cheng to Phonsavan – 120 km

Before we leave, we’ll finish our look at that very interesting and historically significant area. Then we leave for Phonsavan which we will reach in the afternoon passing through Xam Thong LS20 which played it’s own major role in the war. The new school stands on the old Hospitals base and the Air America bunk House Chimney also still stands.

On arrival there, we will visit the Plain of Jars. The Plain of Jars is a huge site of stone urns, some with lids. What the jars were used for isn’t known, but there are many guesses. The most popular guess is that the jars were used as a ‘burial ground’. Your guess could well be as good as anybody else’s. Time permitting we can visit other sites such as the 1000 Step Mountain or the Spoon Village. The evening will see us at our local guesthouse and our last night ‘on the road’.

Day 4: Phonsavan to Luang Prabang – 240 km

We’ll be up and away early for our last day, heading back via Phoukoun and Route 13. That route takes us high into the mountains, traversing bends, twists, and turns all the way. Exciting roads, exciting riding, and ‘jaw dropping’ views which would be very hard to beat anywhere in the world. Finally, we arrive in Luang Prabang and our final dinner together, undoubtedly talking about the great time we’ve had and our visit to the ‘most secret place on Earth’.
