Respect and admiration for nature is already represented in the resort’s logo, which was idealized by the rupestrian inscriptions on the Morro das Aranhas (Spider Hill). Guests at Costão do Santinho have the privileged experience of being within an area of 750 thousand m² (8,000 sq. ft.), where there are rocky coastlines and dunes preserved in a Private Natural Patrimony Reserve, denominated as such, in 1999.

There are furthermore ecological itineraries in which guests are in direct contact with all the reserve's biodiversity, such as the lagoons and streams not to mention the magnificent archeological museums. The Costão ecological itinerary includes: Ecological trail Moçambique Beach Ingleses Beach Dunes Top of Morro das Aranhas Top of Morro dos Ingleses Trip round Morro das Aranhas Morro dos Ingleses Point Lagoa da Conceição Coastline Costão do Santinho is the only resort in Brazil , which has open air Archeological Museums. The Archeological museum at Santinho Beach is home to historic patrimony, which dates back about 5 thousand years. In this Santinho beach paradise, there are rupestrian inscriptions on the sides of the basaltic rocks, which always face the ocean. The logo of Costão do Santinho Resort and its SPA, can be seen on one of these rocks. There is another paradisiacal retreat at the side of the Porto do Costão Marina, at Ingleses Beach. The Brunidores (Burnishers) museum is an archeological site, which has a variety of rocks, which were used to make tools and other basic stone artifacts, and it is known as Burnishers or Lithic Workshops. The resort judges that to understand and preserve this Rupestrian Art is more than an ecological attitude, it is an enormous privilege, as these inscriptions are the only vestige, which has been left consciously and voluntarily by pre-historic beings.
