Connemara Ponies at Dusk While driving through Ireland's Connemara region at the end of a dreary rainy day, two Connemara ponies unexpectedly ran alongside our car and began to play. I slammed on the brakes and started shooting through the passenger window while the ponies put on a show as if they knew we were the only people around for miles. Perfect ending to an amazing family vacation. (Joshua Boyd/National Geographic Traveler Photo Contest)

Cowboy in a Ribbon of Light Rodeos always provide a sense of place. There's action, dirt, pride, you name it. It's a loud, flashy sport, with cheering and showboating. But on the underbelly are quiet moments. The moments between bucking broncs, beer drinking and the announcers crude jokes. Moments like this one, where a young boy waits patiently for the next horse to come charging out of the chutes. (Dylan Brown/National Geographic Traveler Photo Contest)

Go-afoss Go-afoss is one of the most spectacular waterfalls in Iceland. Located in the central north of the island translucent aqua water cascades over the horseshoe shaped falls and races down the canyon. Icicles cling to its rock ledges and fresh snow lies across the landscape under soft diffuse light of the type that only Iceland can deliver.

Hagia Sophia Museum Hagia Sophia is the one of the most visited museums and most prominent monuments in the world in terms of art and the history of architecture. It has also been called "the eighth wonder of the world" by East Roman Philon as far back as the 6th century. It was used as a church for 916 years but, following the conquest of Istanbul by Fatih Sultan Mehmed, the Hagia Sophia was converted into mosque. Afterwards, it was used as a mosque for 482 years. Under the order of Atatrk and the decision of the Council of Ministers, Hagia Sophia was converted into a museum in 1935. (Melih Sular/National Geographic Traveler Photo Contest)

Honor With the death of the King Father, hundreds of thousands of Cambodian citizens gathered in the streets of Phnom Penh to mourn. Children and adults alike wait for hours in the searing khmer sun, waiting for his body to be brought to the Royal Palace. Boy Scouts and Cambodian Red Cross volunteers distribute bottled water to those who are showing signs of dehydration. People are fainting in the crowd as heat exhaustion takes over. No one is sure when the King will arrive yet no one dares to give up their spot. Here, Buddhist monks line Sothearos Blvd. awaiting the return of the King Father.
