This paper outlines a description of research carried out at a public university in Colombia where students of the Hospitality and Tourism Management program took four general English levels in 2017 as a requirement to graduate. According to the data collected, these levels were not enough to acquire the necessary knowledge and skills to interact in English. This need, determined through questionnaires, and a CNA report were the starting point of this research study, whose main objective was to enrich students' language learning skills and knowledge through a CLIL curriculum. This participatory action research is framed within a qualitative study. After designing, implementing, and piloting one unit, including four lessons, we determined that not only students' language learning skills can be improved but also their confidence, participation, solidarity, and awareness of their and others' learning process through the activities designed and strategies proposed by this approach.
