In order to study the matter, two highly competitve island destinations in Thailand (Koh Tao & Phi Phi) were identified as subjects for further research. Contributing factors in the context of brand identity were then applied and studied separately on both destinations, in order to identify the factors of importance.  The aim of this study is to identify competitive island destinations in the competitive tourism region of Thailand and, from a visitor perspective, determine what factors in destination branding that are important to differentiate and create an identity on the market. To conduct the study several methodological approaches were carefully chosen to collect empirical data. The collected data were then analyzed based on a theoretical framework.
