Around half five to half six. The alms round happens at first light along the main street. Whether you go at all is a real question, and it has its own section below.
Around half six. The morning produce market fills the lane running between Kitsalat Road and the palace museum, and to our mind the first half hour after light is the best of the day: river fish still moving, banana flowers, bundles of dill and mint, women selling three things each. Buy sticky rice and a bag of something fried and eat it standing up. Traders generally keep going well into the morning — the standing guidance for this market has it dispersing at around eleven — so a late start is not the catastrophe it is usually made out to be, but the produce and the light are both better early.
Roughly eight to ten. The Royal Palace Museum, built in the early twentieth century for King Sisavang Vong, is to our mind the one indoor sight worth queuing for. Shoes and bags go into lockers, photography inside is not permitted, and the interiors — the throne room in red glass mosaic, the king's bedroom left much as it was — take about an hour. In the grounds stands the Haw Pha Bang, the pavilion built for the Phra Bang, the Buddha image the town is named for. Sources disagree about where the image actually sits: it is generally reported to have been moved into the pavilion in 2013, but it has also been described as displayed in a corner room of the palace itself, so ask at the ticket desk rather than walking to the wrong building. Either way it is not the slab of gold the name implies. The image stands a little over eighty centimetres and is cast from thong, an alloy of bronze, gold and silver. The museum is generally closed one day a week, usually reported as Tuesday, and shuts for a long lunch; check the board at the gate on your first evening and build the day around it. Cross the road afterwards for Wat Mai and its gilded bas-relief facade: ten minutes, no more.
Roughly ten to half eleven. Walk north-east up Sisavangvong Road, which becomes Sakkaline, to Wat Xieng Thong at the tip of the peninsula. Built in 1559–60 under King Setthathirath, it is the one building here we would keep if we could keep only one: the roofline of the sim sweeps almost to the ground, and the glass mosaic tree of life on the rear gable is the image we came away with. Give it forty minutes and walk the whole compound rather than just the main hall, because the royal funerary carriage house at the back is easy to miss and worth the detour.
About half eleven to three. Stop. This is not laziness, it is the local timetable. Take a long lunch, go back to the room, swim if there is water. Luang Prabang between noon and three in the dry season is usually unpleasant, and the light is flat for photographs anyway.
Around three to half four. Two small museums will do more for your understanding of Laos than another six temples. The Traditional Arts and Ethnology Centre, which dates itself to 2006 and describes itself now as a museum, learning centre and handicraft shops devoted to the ethnic cultures and artisans of Laos, is genuinely well made: one floor, an hour, and you leave able to tell a Hmong textile from a Tai Daeng one. It is not at the foot of Phousi, whatever you may read elsewhere. It stands on its own small rise behind the Dara Market in Ban Khamyong, a few minutes' walk from the post office intersection and something like half a kilometre south-east of the hill, so build in the walk. It is usually closed on Mondays, which deserves exactly the same attention as the palace's closed day and catches at least as many people. The UXO Lao Visitors Centre, which explains the unexploded ordnance still lying in the ground across the north, is smaller; entry is usually free with a donation invited, at the time of writing, and it generally keeps short weekday hours, so confirm through your accommodation before you plan an afternoon around it. Neither is cheerful. Both are short.
About half four. Mount Phousi. The stair from the Sisavangvong side takes ten to fifteen minutes at a steady pace up a hill of about a hundred metres; quoted step counts vary by around fifty depending on who is counting and where they start, so treat any precise figure with suspicion. At sunset the hill is properly crowded, and the crowding has two separate parts: a queue on the stairs and a crush on the summit terrace. Climbing from the Nam Khan side, past the small shrines and the Buddha footprint, is quieter and shadier — but it solves only the queue, and delivers you into the same crush at the top. The summit problem is fixed by timing, not by route: go up about ninety minutes before sunset and come down as the crowd arrives, or climb at dawn instead. If you decide the alms round is not yours to watch, day one's first hour is free, and that is where a dawn climb belongs.
From about five. The night market fills the main street with handicrafts and Hmong textiles. Prices are negotiable, quality varies enormously, and the food lane running off it is where most visitors end up eating.
Three trips compete for this morning, and a three-day plan has room for exactly one. Choose deliberately rather than hoping to fit two.
Kuang Si is the standard choice and the right one on a first visit: turquoise pools stepping down through forest, cold enough to be a genuine relief. It lies about thirty kilometres away by road, south-west of town rather than due south — worth knowing when you are reading a map or checking where a driver is heading. Reckon on roughly forty-five minutes to an hour each way by shared minivan or tuk-tuk, settle the return arrangement before you get in, and set off by around eight so that you arrive ahead of the coaches; leave at ten or so and you will queue for the pools. The Free the Bears sanctuary at the entrance is not an add-on to be walked past — fifteen minutes there explains why the animals are there at all. You will be back for a late lunch, with the rest of the day loose.
The alternative for anyone who would rather be on the river than in it is the slow boat upstream to the Pak Ou caves, two chambers in a limestone cliff at the mouth of the Nam Ou packed with thousands of Buddha images left by pilgrims over centuries. The caves are modest and the upper one needs a torch; the journey is the point. Upstream against the current usually takes somewhere between an hour and a half and two hours depending on the boat and the water, and rather less coming down, with karst rising out of brown water and villages along the banks. Boats often pause at Ban Xang Hai, the riverside village known for its rice whisky. Take a hat, because there is no shade on the water.
Tad Sae, the third option, is seasonal in a way Kuang Si is not. It is reached by road east of town and a short boat crossing of the Nam Khan, and it runs properly from roughly the start of the rains until around November or December, then can be dry or close to it through the late dry season. Ask locally the day before rather than committing a morning to it on spec.
The decision rule is simple enough. If it is your first visit, or you want to swim, take Kuang Si. If you have swum enough or the heat is not the problem, take the boat to Pak Ou. Consider Tad Sae only when someone in town has confirmed there is water in it. The trips you do not choose are the best argument for a fourth night: Pak Ou fits a fourth morning neatly, since it is over by early afternoon.
