Over at Heroines Monument, as part of the celebrations of two sisters who saved Phuket from the Burmese, they're having a party.
Every night from 15th March to 24th March, there's live music from a popular band, a fun fair and food festival. I went to last nights show, but the main act was on very late, 10:30pm, but there was a good support band before them. The last two days are a beauty competition, I'm too old to enter, the age limit is 25. They should have a beauty competition for the older women too!
The festival is in the evenings over the next week, during the day there are still plenty of stalls open, you can't miss it, it's at the Heroines Monument in the center of Phuket, shown on the map below.
