The land and marine coastal environment makes this exceptional site we live our adventure on! Without special care and attention, without utter respect, we compromise the future of our common heritage. DUNE Snorkeling is totally in line with a policy of permanent improvement regarding the impact of our activities on environmental issues. The choice to practice our activities on these unique and protected spots compels us to work exclusively with specifically trained guides in order to guarantee the utter respect of these discovery sites. The members of the DUNE network cofounded the ATR charter (acting for a responsible tourism) back in 2001, and committed to the ‘charter of the responsible diver’ in 2007 with Longitude 181. For 30 years, DUNE’s tour operator partners have been allowing only small groups to access the richest and most fragile spots, thus favouring a greater respect for local populations and environments.
