One of the highlights of a visit to Luang Prabang is to get up at dawn and watch the monks make their way down Sisavangvong Street from the main temple collecting alms (balls of sticky rice) from townsfolk , in their bowls. (Check with your accommodation hosts for the best time).
Villa Santi Hotel has a great location for this, as many monks pass by the front gate at dawn and then slowly making their way back to the temple in ones and twos all morning. (So if you are not able to get ups so early, it’s still possible to share a bit of the experience later in the day).
It’s peaceful and interesting but also a wonderful opportunity for some great photos. Just remember to keep a respectful distance.
