The park charges a Thai tourist Bt20 for the entry fee and a foreign tourist, 10 times higher or Bt200.
But the group of 50 Malaysian tourists refused to pay the fee at all, Panapol Chiwaserichon, chief of the Tarutao park, said.
Panapol said he did not want to get tough with tourists so he would hold a meeting with tourist boast and tourist company operators to discuss how to collect the entry fee from their clients.
