The larger bays on this coast are Tumaco, Choco, Magdalena, Cabita, Coqui, Puerto Utria, Solano, Cupica and Octavia - some of them affording exceptionally safe and well-sheltered harbours.
Besides this, the extreme unhealthiness of its most productive regions, the Choco and Barbacoas districts on the Pacific slope, has been a serious obstacle to foreign enterprise.
It is found in many parts of the country, but chiefly in the Choco and Barbacoas districts, the annual export from the former being about 10,000 in value.
