Places columbus explored included all except : south america caribbean islands india central america

He explored everything except India.

The correct answer is India. Cristopher Columbus never reached India. He was sent by the Spanish Crown to find a western sea route to get to India faster, because Europeans considered India as one of the richest parts of the world, in terms of natural resources and spices. On this route, he crushed into the American continent and explored the Central and South American coasts.
