Pakbeng is in Bakeo Province, Northern Laos.
This small village lies half-way between Huay Xai and Luang Prabang, perched high on the banks of the Mekong river. You will likely be in Pakbeng because the two-day boat between Huay Xai and Luang Prabang has to stop for the night, and a number of guesthouses have been set up to cater for the passing tourists. It`s also the eastern end of Road 2, originating in Udom Xai. To call Pakbeng sleepy is an understatement. It's quiet to the point of being dead. Still there are sufficient restaurants for one pleasant night.
24 hour electricity arrived relatively recently in Pakbeng, but you'll still experience regular power outages (bring a torch or mobile) and find most of the town is shut down by 22:00. What Pakbeng does have to offer is a good night's sleep and sunset views over a particularly scenic stretch of the Mekong.
Most visitors will have to stop here over-night on the slow-boat trip to/from Luang Prabang. It`s also possible to arrive by speedboat en route to the north. Much more uncomfortable than the slow boat, however you will arrive before the slowboat so you have the option of choosing a guesthouse and showering with no queues. You also get to see the town as the only Westerner. Another possibility is to reach the place by bus-- this is a rough and long option.
The boat landing is at the end of Rd 2 on the Mekong. Slow boats leave in the morning in both directions. They depart when full but expect to start at around 09:00. Arrive early to get one of the better seats (as far away from the loud engine as possible). The dropping off boat normally arrives at about 17:00, but this is Laos, so bear in mind that this is a guideline. Laos transportation departs when the driver can be bothered. It's best just to relax and enjoy the peace and quiet. And have a beer, of course.
Pick-ups make the trip to Udom Xai around 07:00 and leave at the northern end of town on Rd 2.
A bus Leaves at 12:00 from Muang Ngeun (near the Thai-Lao border ), costs 30,000 kip, and takes 1.5 hours.
There are only a few streets, so walk around. Most of the guesthouses are along the first 50 m of the main street as you head up the bank.
With the roads and particularly the rocky bank just above the boat landing being very steep, it might seem tempting to accept an offer for someone to carry your bag for you. Just ensure that if you do so you agree on the size of the tip beforehand.
There is nothing much to see except the mighty Mekong and rural Laos life.
A couple of local wats may interest the obsessive temple enthusiast.
Find a bed, eat something and sleep ... and prepare for another day on the boat
Recently a local guy  there started trekkings, with a sleepover in a hilltribe village . Can be nice before you get on that slowboat again.
Pakbeng is remote and offers very little in the way of shopping, but if you're about to spend the rest of the day on a boat it would be a good idea to pick up snacks from the row of market stalls that line the main road in the morning. There is 2 atm's, bcel and ldb, in at the end of guesthouse strip and third one for apb being built (11/2014) farther towards the big streert.
Several guesthouses and some "restaurants" offer food, but don`t expect anything special. There's an Indian restaurant with decent curries along the main street, called "Hassan". The friendly manager will also package meals for consumption on the slow-boat. Be careful while paying though, he might tend to give you back too litle or hand you unusable (too old, broken) dollar-notes. (Don't accept a dollar-note that's a little ripped, it will be unusable later)
Locals set up small sandwich stands along the road to the waterfront each morning. You can buy basic sandwiches of bread and Laughing Cow cheese. Or ask your guest house to provide you with a packed lunch, as you are going to be in for a 9 hour boat ride without meals. Some boats do have some food and drinks for sale too.
Standard beer options are available from guest houses, at inflated prices. To ensure a good nights sleep, try the local "lao-lao bong" -- water poured over fermented rice and slipped through a straw.
Standards are low at this village near-the-end-of-the-world. Just look around as things change fast. The guest houses in Pakbeng are all along the main street, just hundred metres away from the boat docking area. A room with shared bathroom will cost about US$3, while a private bathroom will costs an extra US$1-2 (rooms can mostly be paid in Thai baht and Lao kip as well). There might be places where you can get a room for US$2, but you 'll have to search long and bargain hard. Considering hot water: make sure that your bathroom has an individual electric water heater, as there are guest houses with central boilers that only provide a certain amount of hot water for the whole guest house on a first-come-first-serve basis.
Touts are prevalent in Pakbeng, and you will be bothered. However, these touts are very laid back, especially compared to Thailand. If you are after a really cheap option, it is possible to get a mattress and a mosquito net under a veranda for about US$0.50. Just watch out for monkeys.
It is possible, but not necessary, to book accommodation in Pakbeng in advance, as there are plenty of guest houses and almost all visitors stay only one night. Do note that before sunset the dock is fairly active and there may be substantial noise until things cease for the day.
The exception to this rule is if you're looking for something a little more upmarket, in which case you have only two choices.
Pakbeng is in the small town so there is nothing to worry
Huay Xai and Luang Prabang by boat are the normal destinations for anyone leaving Pakbeng. The slowboat to Luang Prabang is scheduled to leave at 7:30am but doesn't depart until 9:00-9:30am on a good day.
Bus to Muang Xay (also known as Udomxai) leaves between 8.30 and 9.00. The price is 50,000 kip and the ride takes around 4 hours. The bus station is about 30 minute walk away from the slow boat pier. When you get to the intersection of Pakbeng road and the big road, turn right and walk past the market and petrol station and you'll see the station (a wooden house) on your right.
