The National Geographic magazine has a competition for travel photos every year.
You can go to this page to see the winners or all competition entries for 2015.
Here is an example:
“The night before this photo, we tried all day to get a good photo of the endangered white rhino. Skulking through the grass carefully, trying to stay 30 feet away to be safe, didn’t provide me the photo I was hoping for. In the morning, however, I woke up to all three rhinos grazing in front of me”. Ziwa Rhino Sanctuary, Uganda.
