"Namibia is other worldly. The northerly Kunene region is one of the most remote areas on the planet, vistas are never ending, and the landscape is lunar-esque. The Skeleton Coast is raw, desolate and eerily beautiful. A raging sea meets an angry coastline, plus there are myriad species of desert adapted wildlife. The Namib desert is the oldest in the world and home to the highest sand dunes— this majestic region is a photographer's dream." Would you like to visit Namibia's deserts and coastline?

"People often think of China as an urban setting and rarely consider that it's the fourth largest country in the world with many natural wonders, from the southwest jungles to the Gobi Desert in the northwest. People visiting China will often include outdoor travel within the context of a larger, heritage-based trip. In the Huangshan area, you can walk along the ridges of the stunning Yellow Mountains one day and then on the next day they can bike or trek past bamboo forests through verdant rice valleys to an assortment of picturesque villages."

"I have to start with Plitvice Lakes in Croatia, along with sleeping in the plush new treehouses near the National Park. I would also suggest a seven-day cruise around Kornati islands with a visit to Telašćica Nature Park and, of course, island Mljet—which is often overlooked and provides one of the most pristine settings in the Mediterranean. Mljet is considered the mythical island of Ogygia where, according to Homer, Caliope held Odysseus prisoner." Are you interested in visiting Croatia's lakes and islands?

"Book a 6-day rafting trip through the heart of the Grand Canyon via the Colorado River. Many outfitters have been running the trips for 20 or more years, and the guides really know the history of the canyon. The food is great, and you'll marvel at being a mile down in a canyon, camping on the banks at night, and roaring through the rapids from Crystal to Lava Falls. At the end, escape nature by helicoptering out to Las Vegas for a show. Kids love it (but it's best if they are 10 and above)." Have you visited the Grand Canyon?

"The Ngorongoro Crater is the world's largest inactive volcanic caldera, formed when a volcano erupted and then collapsed inward almost three million years ago. Now it's a 12 mile wide hole in the earth's crust with mesmerizing 2,000 foot vertical walls. The cinematic light with the vertical backdrops are the things a photographer's dreams are made of. The crater boasts the densest concentration of iconic wildlife in Africa: seven prides of lion, lots of endangered black rhino, huge herds of zebra and wildebeest, leopards, giraffes, ostrich, warthogs, and jackals roam the open grasslands, dense forests, and lakes full of pink flamingos. Proximate to the crater is Africa's greatest natural wonder, the Great Migration." Would you like to visit Tanzania's Ngorongoro Crater?
