There is a continual search to understand the role of social networks in people's lives and what the intensity of their use represents. When it comes to travel, there have been studies about the sharing of travelers’ experiences on the Internet, e.g., those of Ek Styvén and Foster (2018), Jadhav et al. (2018), Sedera et al. (2017), Sigala (2016), Bilgihan et al. (2016), Munar and Jacobsen (2014), and studies on how travel contributes to raising self-esteem and happiness, e.g., those of Olague de La Cruz, Flores Villanueva and Garza Villegas (2017), McCabe and Johnson (2013) and Abou-Zeid and Ben-Akiva (2012). The present study aims to understand the relationship between happiness and the use of social networks in travel experiences. It was a descriptive survey, using a quantitative approach. The survey was carried out with people who had traveled for tourism purposes in the past two years. An analysis of 411 valid response to a structured questionnaire was used, seeking to identify a relationship between happiness, travel experience and social media. Finally, it was observed that the use of social networks influences the sharing of travel experiences, just as satisfaction with the most recent trip also influences the traveler’s satisfaction with life and happiness.
