Lagos is one of the most visited places both in the region of the Algarve as well as Portugal in general. More than 60% of its territory is a nature conservation area and all of the beaches and the marina of Lagos have been awarded with the Blue Flag certification. There is a rich cultural heritage in Lagos with many important monumental and historic buildings. Local traditions, heritage and culture are well preserved and actively promoted. In order to reduce the environmental impacts of tourism in Lagos and to respond to the recent increase in environmental awareness among tourists, several hotels in Lagos have demonstrated their corporate commitment to sustainability. In recent years Lagos won numerous awards for its diverse sustainability practices.

Portugal participated in the 2019 Sustainable Top 100 Destination Awards at ITB Berlin by submitting a sustainable tourism story.
