    • Hi Elsa,

      There are no scheduled times or dates that I am aware of. Sometimes it is difficult to pinpoint the date and time of the buffalo fighting; however, these fights usually take place at the many stadiums around Koh Samui in the evenings.

      Typical of the small island culture, emails and phone numbers to find out this sort of information are not readily available. You are best to ask at your place of accommodation, as locals tend to have up to date information on where and when the fights will be scheduled.

      As for price, this is variable depending on the stadium. Plan for between 100-200 Baht – however this is not set in stone.

      You may find regular fights occurring along the North Coast (Bang Po Beach, Ban Tai) at Bang Makham.

      Best regards,
      Jess
