Nong Khiaw (Nong Kiau or Nong Kiew) is a beautiful rustic little town on the bank of the Ou River in Laos. It is squeezed in between some of the most fantastic limestone mountains north of Vang Vieng.
Many travellers pass through on the way up river to the even more isolated Muang Ngoi, but Nong Khiaw has a plenty of charm, a decent range of accommodation, plus conveniences suchas 24 hour electricity and a connection to the road network for those interested in exploring the surrounding area.
Buses from Udomxay are scheduled 1 time daily if passengers enough (3-4 hours) to Nong Khiaw but may not run on time, or at all, during the low season (depending on passenger numbers). It is possible to negotiate a fare on either the Vang Vieng or Luang Prabang bound bus and disembark at Pak Mong (where the highway turns south). From here a tuk-tuk will take you the last hour or so to Nong Khiaw for around 30,000 kip per person.
Buses from Nong Khiaw:
The bus/minivan station in Nong Khiaw is on the edge of town on the western side of the river.
To Luang Prabang and Udomxay run daily at around 09:00 & 11:00 price 45,000 Kip. 4 hrs.+ -
To Luang Prabang by Minivan leaving at changing hours and costs 50,000 kip per person.
To Luang Namtha you have to take the bus to Udomxay and than change the bus which gives you a quite late arrival in Luang Namtha. It cost 40,000 kip to Udomxay
To Muang Khua or Phongsali you need to go to Udomxay (11:00) as well, change bus
To Vieng Thong and Sam Neua (near Viengxay and Vietnam border) the bus starts originally from Luang Prabang and you have to be on call around 12.30 +!
The buses run hardly ever on time. Buy your ticket in advance and leave your name! Private minivan to Luang Prabang can cost as low as 500,000 kip. especially if drivers have empty returns.
Over the course of the last couple of year a number of tour operators have opened their tour office in Nong Khiaw so there is suddenly something more to see. They will bring you out for various trips, hikes, river tours, bamboo raft workshop, village stay. Some of the tours can be found online. 
Pha Tok Caves, (about 2km outside town on the far side of the river from the boat landing and bus station). This cave set high in a limestone cliff sheltered villagers and Pathet Lao fighters during the Second Indochina war. The caves are accessed via steep concrete steps, and inside a few signs identify points where command posts were stationed. Entrance fees are collected at the bottom where you can also borrow a torch. The trail to the cave passes through many rice paddies and a small section of jungle. If you ask the people at the "ticket desk", you should be able to arrange a boat ride back to Nong Khiaw from a local. For 2 people in the very small canoe type longtail boats that can seat max 2 people plus driver the price is around 50,000 kip. 5,000 kip. edit
Be careful with "guides" who try to show you the second (there is 2 caves there) cave after you visit by yourself the first one. He will ask to you tips (50'000-80'000kip) for is help (that you don't need for sure). To see the second cave by yourself take the little pass at your left when you are at the entry of the first one.
Walk around the village enjoying the village feel with great views over the Nam Ou river. There is a small temple complex in the centre of town.
Walk or bicycle on the dirt road behind the Riverside resort for some scenic views and nature.
Rated one of the best hikes in Laos is the is the "100 Waterfalls" trek operated by Tiger Trail and Fair trek initiative 
Some of thier treks go to the interactive culture lodge.

Rent a mountain bike and push eastwards to remote Khmu and Hmong villages. Since there are is a lot of going up and down it makes sense to rent a mountain bike.

Riverside Guest House rents mountain bikes for 50,000 kip and city bikes for 10,000 kip.

Take the steep trail up to the viewpoint for a wonderful 360° view on the nearby valleys. Access off the main road (look for signs or ask). It costs 20000 kip (bottle of water included) and takes 1-1.5 hours to reach top.
Fantastic sunset view but bring a torchlight to come down cause it's not very easy descending.
In case you plan to do the hike in the morning, you will be able to see at the sun rising from the clouds covering the surroundings of the river each morning.
Next to the bridge, there are several small beaches where tourists can enjoy the sun and cool in the Nam Ou river.
The few small shops on the main street cater more for locals than tourists, and offer little more than basic necessities.
Money can be changed near the boat landing - Youth travel agency or over the Bridge at Riverside Guest House. Riverside can also offer cash advances on credit cards.

You can take a public boat to Luang Prabang; the trip takes approximately 8 hours and costs 110,000 kip per person. Purchase tickets at the office near the boat landing (near the bridge). The boat won't leave until all seats are filled - either 12 or 18. As of mid-April, the boat left at 11:00. Alternatively, you can arrange a private boat. Riverside Eco-lodge will arrange it for 1.5 million kip for the entire boat, or you can ask around. Takes only about 6 hours by private boat which makes fewer stops with less waiting time, and you can make as many stops as you want on the way.
Boats that go up the river to Muang Ngoi Neua leave regularly in the high season until 15:00 –takes 1 hour costs 25,000 kip. In low season there is one boat definitively at 9:30 and another at 14:00. Some of the boats continue to Muang Khua
Boats on the Nam Ou:
To Muang Ngoi the public boats leaves around 11.00 and around 14:00.
The price is around 25.000 kip.
Private boats coat 300,000-400,000 kip one way, but can be cheaper if the person driving needs to go anyway. Speedboat do not operate anymore.
To Luang Prabang
Public boats are not so common but normally start at 11:00-12:00The road offers a much faster way to go but less interesting. A private boat down to Luang Prabang (6-7 hours) would cost about 1 to 1.3 million kip. It’s recommended to get a small group together and share the cost as the trip is worth it. You can leave your name at the boat station! If it runs like a public boat you are supposed to pay around 150,000 Kip per person (4 times the price of a public Minivan) In high season there are normally enough people to go.
Speedboat to LPB costs 1 million kip and takes 2.5 hrs. (up to 6 persons)
Further on the Nam Ou to Muang Khua
The boats leave around 11.00 if there are enough people to fill it. A charter cost about 1.1 million kio, and takes about 6 hours. Visit the boat landing and pass by a few times to check if there are some/enough people. Speedboats to Muang Khua costs 1 million kip and, and takes 2.5 hours. Especially the part north of Muang Ngoi is extremely picturesque and worth visiting/cruising through. You can do that also with a day cruise from Muang Ngoi in a small boat.
Remember: In Laos even the public transportation is mostly privately owned and drivers stand in a queue to grab the next job/drive. So if there is no profit, they won’t go! If travelling alone you might be waiting for the next boat or busload of people to turn up.
