Albeit the increasing popularity of the walking-tour tourism, little effort has been invested to understand people`s motivation for walking-tours and to develop a related measurement scale. The purpose of this study was to develop and validate a walking-tour scale as perviously addressed by Park & Hyun (2009). Towards this goal, as suggested by Park & Hyun, eight dimensions were purified through a means of expert judgement and pre-testing. Following this, a survey of 300 participants who visited Course 7 of Jeju Ollegil was analysed to validate the dimensions of the measures. The scale items were then purified to examine the scale`s dimensionality, and to evaluate the scale`s validity, factor structure, and reliability including cross-validation. The scale development procedure yielded a four factor measurement scale with acceptable levels of reliability and validity. Four motivational dimensions (14 items) of walking-tour were labelled: Self-introspection, Self-meditation, Self-achievement, and Self-purification. The findings and applications of the developed scale are discussed both in terms of methodological and theoretical implications.
