||The Archipelago of the Azores has a high potential for tourism differentiation at an international level due to its distinctive and unique characteristics and natural beauty. Seascapes have high biological diversity, ecological and economic connectivity, and aesthetic and cultural value (Atkinson et al., 2011), although seldom subjected to assessments. Additionally, marine geological heritage has been only occasionally exploited by Azorean companies, mostly because there is a lack of data about underwater geodiversity, geological heritage, and its valuation, for recreational purposes. This study (within the project SCAPETOUR – SeaSCAPEs promotion to diversify TOURistic products) aimed to analyze visitors perception regarding the importance of seascapes features and their value, more specifically: a detailed and full characterization as well as sectorial analyses of selected coastal and underwater trails for tourism and a valuation of seascapes for tourism and conservation purposes, including visitors perception regarding the seascape features. In the context of species conservation and ecosystem protection, it is important to increase users and stakeholders knowledge on the natural value of the assets to promote sustainable use of the ocean and marine life.
