For travelers who want Colombia’s wilder side. Caño Cristales is the best-known name here — a river that runs red, yellow, and green for a few months a year, thanks to an aquatic plant found almost nowhere else. It’s remote, and worth the effort to reach.

The Colombian Amazon, reached by boat from Leticia, is a genuinely different trip from the rest of the country. And the Pacific coast is one most visitors never consider — known among those who do for whale watching season and beaches that stay empty.
