Just a word of warning, when you arrive in Luang Prabang you will find many tours on offer. Many to go and see the elephants in their natural habitat. Unfortunately, not all tour companies are genuine, in terms of conservation. I personally recommend Tiger Trail Tours. It is genuinely set up in order to help the elephant. They have an elephant park which you get to visit, it is the elephants permanent home. Other tour companies only rent the poor elephant for the tourist period and then when they are done with them they are sent back to dangerous tree lopping activities. So ask the hard questions about where their elephants come from, do they live in a permanent conservation camp? etc etc. (for those of you who are interested in putting money towards saving the elephant).
On a happier, most exciting point after an elephant tour (could last a few days) I would then also highly recommend trying some of the fantastic value massages ($14 for one hour massage, 30 minute body mask, and sauna...aaahhhh).
All this excitement has left an impression on me and I fly back to L.P in two weeks, to try it all again and to chill out. Low tourist season I believe,so that would be good. Remember not walk about too much as USA landmines are still blowing up locals and unsuspecting tourists. So be careful where you wonder off to !
