Entries for the 25th annual National Geographic Traveler photo contest have started to flood in, and as expected, many of them are spectacular.
Nearly 6,000 photos have been submitted to the competition (you can see all of the entries here), and we have to say, whoever's judging has their work cut out for them. The winner of the contest will receive a 10-day trip to the Galápagos and have their photo featured in an issue of the magazine.
Amateur photographers can submit photos until June 30, 2013 and each entry costs $15. Click here to check out some past National Geographic photos, and take a look some of this year's submissions below:
