Most nights you will find a market or walking street somewhere.

Chaweng - There is a market of sort most nights opposite the lake on the one way system and also near the northern end of the boundary wall for Centara Grand.  There is also a market  All start around 5pm every night.



UPDATE - The market in Bophut Fishermans village was suspended on 17 June 2016 - check if the market is still operating before heading over to Bophut. Bophut - Fisherman’s village from 5 pm till 11pm first and largest on Samui and usually very busy if weather permit.  Large amount of street food and clothing as well as souvenirs and gifts.  The road is closed to traffic so find parking outside the village and walk on in  Allow a few hours to stroll around.  Most restaurants are open and enjoying the crowds.  



Nathon [the capital] walking street is along a minor street between the main [one way] road and the beach road.  Starts around 5pm onwards.  Roads closed to traffic with prices usually a bit cheaper than other markets.  A great place to eat and shop, some different food is sometimes available here
