The children's use of technology is increasing year by year and recent statistics show that children receive their first smartphone and autonomously navigate the Web when they are 10.3 years old (on average). Nevertheless, while the number of tourism packages for families with children grows, the number of websites that can be directly visited by children is small; more relevant, is the number of tourism applications developed for children. This paper discusses the design of usable and accessible websites for children, and proposes, as a case study, our experience on a dedicated section of the tourism website of a Naturalistic Oasis located close to Treviso, in Italy.
