The current study develops a second order measurement instrument for sustainable tourist behaviour through confirmatory factor analysis from tourists' responses based on three prominent destinations in India namely, Goa, Munnar and Manali. Factorial validity, invariance analysis and nomological validity were also assessed. Resultsshowed that STB is a second order reflective factor consisting of destination specific pro-environmental, socially responsible, environmental learning, cultural and economically favourable behaviours. Furthermore, while environmental engagement is a significant enabler for STB, the latter contributes significantly in the development of memorable experiences and tourist satisfaction.
