Alan Taylor, The Atlantic:

The winning entries in the 25th annual National Geographic Traveler Photo Contest have just been announced. First prize winner Wagner Araujo will receive a 10-day Galapagos expedition for two for his image of competitors in the Brazilian Aquathlon. Collected here are the ten 2013 prize winning photos, plus the Viewers’ Choice selection. Photos and captions by the photographers.

I’m partial to #4.
