What perhaps strikes visitors most upon arrival at the NamibRand Nature Reserve, a 445,000-acre desert conservation area the size of some small countries, is the quiet solitude and utter enormity of the desert, one of the oldest in the world.

The four camps on the reserve share one overarching philosophy: exist in harmony with this landscape. At the tastefully posh Dunes Lodge, which was revamped in 2009, the nine chalets and Mountain View Suite sit atop elevated decks on stilts and have roll-up canvas walls. The idea: They can be easily dismantled and within months the landscape will look much as it did before.

The main complex has a series of lounges and decks inviting prolonged cocktail hours, as well as a library, wine cellar, tea deck, fireplace, and swimming pool. If you can drag yourself from the serenity of the retreat, there are plenty of ways to explore the lunar landscapes beyond. On a morning, afternoon, or daylong drive, guests witness the starkly beautiful sand dunes and the creatures that call them home, including springboks, bat-eared foxes, spotted hyenas, African wildcats, and oryx. On a scenic flight, guests witness the red sand dunes, canyons, and a shipwreck in Spencer Bay from above. Hot-air balloon rides offer a glimpse of the dunes awash with the colors of the sunrise.

Long, slow hikes are perhaps the best way to appreciate some of the intricacies of the ecosystem, which is just as unique geologically as ecologically. The reserve is just west of the Great Namibian Escarpment, which was formed by the uplift of the southern continent about 120 million years ago. The granite Nubib Mountains rise up in the east, the ever-evolving sand dunes shift about in the west, while volcanic rocks dot the interior. One of the most remarkable sights is the millions of tiny "fairy circles," or mysterious circles in the sand, that dot the desert. Though numerous researchers have studied them, their origin and purpose remain mysterious.

The pristine quality of the reserve is thanks to a pioneering Namibian businessman, who started buying up dilapidated farms in the area in the 1990s. With the help of other donors, the reserve encompasses 12 former livestock farms that have been returned to their natural states. While minimizing the impact on the land at its camps, Wolwedans also runs a foundation that trains local Namibians for jobs in tourism and funds ongoing conservation projects. All of which perhaps deserves a toast while overlooking the fruits of their efforts from one of the Dunes Lodge's expansive decks.
