This paper begins with a study of the protected beach of Gerakas in Zakynthos as a nesting site of the sea turtles Caretta - Caretta, and the actions of the National Marine Park of Zakynthos. Originally thera is a study of the limitations and rules that are set by N.M.P.Z. and of the characteristics of the environment at Gerakas. Human activity is recorded and divided into that of managers and scientists of the Park, and that of the visitors - bathers, while these movements are contrasted with movements of the sea turtles. While the landscape and the naturalness of the area is being analyzed on a human scale and the physical experience of visitors. The facility is designed to eventually guide the bathers in the landscape, informing him of the specialty of Gerakas, leaving him to read the data space and the naturalness of the environment during his descent to the beach, offering or exposing different sightings of the entire landscape or limiting the textures and details of the space around it. It also acts as a separating factor between turtles and humans, leading swimmers in the coastal area where usually are not observed nests of the Caretta-Caretta, while transferring the bathing activity from the beach entirely in water - above or below. The visitor is guided on wooden platforms above the water line, by traces on the path and gives individuals the freedom to choose where they will remain in the region and the relationship they wish to have with the water. Features incorporated in the facility serve the basic needs of visitors in order not to alter the nature of the protected zone. The facility clicked on the landscape and uses penetration piles as support of individual buildings to achieve minimum intervention in the landscape, while the wood is preferred as a primary material of intervention as a natural material and one with the best relationship it might have with the landscape.
