I am always in awe of my friend, Gaelyn, who lives in Arizona. She is a park ranger at the North Rim of the Grand Canyon in spring and summer, and has a background in geology. She is not afraid to travel alone, and has gone to South Africa several times to explore the national parks there, as well as the geology of the area. She takes some of the most beautiful photographs of the animals and scenery there.
If I could pick an iteniary for her next trip, I would suggest Safaris in Namibia:
There are many Safaris in Namibia that will take someone like my friend, who is interested in geology, days to explore. Starting in the northern part of Namibia, there are the Skeleton Coast and the Kaokaland, which is extremely remote. The desert landscapes are vast . They give the impression of utter wilderness, much like areas in northern Arizona. She would be right at home there.
The Southwest of Namibia has some of the most striking desert views in the world, so anyone who is thinking of taking a trip to this country should definitely include a couple of days to a week to explore them. Visitors to this area arrive pre-dawn via a drive through the valley, which is bordered on both sides by huge dunes. The trip is not complete without a hike around Sossusvlei with a climb up one of the largest dunes.
North Central Namibia is home to the Etosha National Park, where you will find extensive grasslands, evaporation pans, and large numbers of exotic wildlife. One drawback to this area, though, is that it is one of the more popular areas to visit so you will have lots of traffic and more people to contend with.
In Southern Namibia you will find the Fish River Canyon, pictures of which remind me of southern Utah in the United States. There are impressive geologic features and the area is home to herds of wild horses.
With so many vistas and areas to visit, you could spend a month or more and not see it all. That, of course, would mean coming back again and again. I would never be bored with travels to Namibia.
