It is necessary to put gasoline in 3 ATVs that travel 27 km of coast all night from 7pm to 8am. The beaches that are monitored range from Playa Manzanillo to Playa Vigía, a large part of this extension of the coast is virgin and in this we can appreciate a great biodiversity, from mangroves, rivers, lagoons, bioluminescent, a great variety of birds, turtles, crocodiles, vegetation and of course the most beautiful sunsets in Oaxaca. By protecting sea turtles we protect an entire ecosystem.
