We can divide the history into two parts, we have the ancient history of Montanita as native place (territories Valdivia culture) and recent history that we can place it back about 40 years ago.
The Valdivia culture has an age of 3500 years BC. Famous for its development and its famous ceramic statue "Venus of Valdivia". More info es.wikipedia.org/wiki/Cultura_Valdivia .
The recent history of Montanita is not far away in time. Surfers few years ago reached the coast and discovered the tip of Montanita and wonderful and powerful waves, impressed by his charm and unspoiled place, he began to spread the word throughout South America. Some time later an Irish opened the first hostel / bar at the top.
From that started coming more and more surfers and hippies who found refuge in this place, peace and kindness by their inhabitants.
About 15 years ago, tourism is emerging as a more constant, that's when people start having hotels, restaurants, hostels and craftsmen.
