(CNN) — The notion of a bona fide desert lapped by the waves of the Caribbean Sea seems so far-fetched that Google automatically changes most searches for "Caribbean desert" to "Caribbean dessert."
Delightful as the ensuing search results might be, they deny netizens the glory of the La Guajira Desert.
Here, at the northernmost tip of South America, sand extends far beyond the spotless beaches, and cacti dominate a parched landscape.
Colombia's wild northeast is slowly making its way onto the tourist map. But patience and a fair dose of discomfort are required to enjoy this barren outpost. Accommodation is basic and extremely limited.
Transportation is by boat or four-wheel-drive only, and even the sturdiest vehicles can run into trouble. (Click through the gallery above for an example.)
