One of my favorite activities in Phuket is go to the open markets, the open markets are really fun to visit, if you love fresh veggies,seafood and fruits this is the place to go. Markets are located all over Phuket at different locations throughout the week. My favorite is the one here, which is located in Kata Beach. I run into a lot of Phuket chefs when I go to the market, quite a few of the restaurants in Phuket pick out there fresh produce for cooking.
If you get a chance during your travels to Phuket, check out some of the markets, they really are a fun place to visit.
