Along with Lago Agrio and Tena/Puerto Misahualli, Coca is the main entry point into the Ecuadorian part of the Amazon.
My suggestion
It's called Coca because the local poplulation chew coca leaves. If you can, I recommend that you try out this custom during while you're on holiday in Ecuador.
Humidity, blasts of hot air, heavy traffic... Embark for Guayaquil, the largest city of Ecuador even though Quito is the capital. We're off for a visit of the "Pearl of the Pacific", from its landscaped river promenade (the Malecón 2000) to the cerro Santa Ana, not to mention the city centre!
Ecuadorian Amazonia possesses the densest biodiversity in the world. With its 6034 square kilometres, the reserve is an incredible mix of rivers and flooded forests (due to the large quantities of annual rainfall in the Amazon). The result? A part of the Amazon that is unique and which will not leave you unaffected...
