Iona National Park

Listen first. The wind moves across the gravel plain with a dry, steady hiss. Small stones shift under your boots. In the early morning a cool grey fog may still lie over the ground and soften the edges of the hills. By midday the light turns hard and white, and the horizon begins to shimmer. This is Iona National Park, in the far southwest of Angola, where the Namib Desert reaches north out of Namibia.

First, a note on geography. The park lies in Namibe Province, on the coastal side of the great escarpment that climbs east toward the cooler Huíla highlands. Many travellers come down from Lubango and the Huíla plateau, so the two regions often appear together in a journey. The drop from the green plateau to this dry country is sudden. In a single day you move from farmland and eucalyptus trees to sand, rock, and open sky.

Iona is Angola's largest national park. It covers roughly 15,000 square kilometres, an area larger than many small countries. The land was first protected as a reserve in the 1930s and became a national park in 1964. Its southern edge follows the Cunene River, which forms the border with Namibia. To the west is the Atlantic coast. Between them lies a wide sweep of dunes, gravel flats, dry riverbeds, and isolated granite hills that rise from the plain.

The desert here exists because of the ocean. The cold Benguela Current flows north along this coast and cools the air above it. That cool air holds moisture but rarely produces rain. Instead it rolls inland as fog, often at night and in the early morning. For many plants and animals, this fog is the main source of water. Beetles, lichens, and low shrubs survive by catching tiny drops from the passing mist.

Now for the first surprise. Scattered across the plains you may see a plant that looks like a heap of torn, leathery ribbons lying on the ground. This is Welwitschia mirabilis. It grows only in this desert belt of southern Angola and Namibia. Each plant has just two leaves. They never fall off. They keep growing from the base for the whole life of the plant, and over time the wind splits them into long, curling strips.

That life can be very long. Scientists estimate that some Welwitschia plants are many hundreds of years old, and the largest may be well over a thousand. The plant was named after the Austrian botanist Friedrich Welwitsch, who documented it in southern Angola in the nineteenth century. Please keep your distance. The roots are shallow, and footsteps or tyres on the soil around a plant can damage it. Look at it as you would look at an old monument.

The wildlife of Iona is adapted to scarcity. Oryx, the large antelope with long straight horns, can go for long periods without drinking. Springbok move in loose groups across the flats. In the rocky hills, Hartmann's mountain zebra climb steep slopes that look impossible for a horse-like animal. Smaller life is everywhere if you look closely — lizards on warm rocks, tracks in the sand, birds that nest in the shade of a single shrub.

The park also carries the marks of Angola's recent history. The country's long civil war ended in 2002. During the war years, conservation work here largely stopped, and many large animals were hunted heavily. Some species declined sharply or disappeared from the area. Since the war, the Angolan government and partners have worked to rebuild protection. In 2020 the conservation organisation African Parks began managing Iona together with the Angolan authorities.

Here is the second surprise. Iona is not an empty wilderness. People live inside the park. Pastoral communities, including Himba and Mucubal herders, move cattle and goats across this land as their families have done for generations. You may see a small settlement of rounded huts, or a herd raising dust on the horizon. Conservation here has to work with these communities, not around them. Water, grazing, and wildlife all share the same dry ground.

Iona also connects to a much larger protected landscape. Across the Cunene River lies Namibia's Skeleton Coast National Park. The two countries have agreed to manage the area together as a transfrontier conservation area — a protected zone that crosses a national border. Animals do not recognise borders. Joined together, the two parks form one of the longest stretches of protected desert coastline in Africa.

Travel here needs planning. Roads are mostly tracks of sand and gravel, and distances between water sources are long. Most visitors come with an experienced local guide or operator and a sturdy four-wheel-drive vehicle. Mobile signal is weak or absent across much of the park. Carry more water than you think you need, and tell someone your route. The desert is calm and beautiful, but it does not forgive mistakes.

The best moments in Iona are often the quiet ones. At dawn the fog lifts slowly and the dunes turn from grey to pale gold. In the late afternoon the low sun throws long shadows from every rock and shrub. At night, far from any city, the stars are bright and dense. The Milky Way crosses the whole sky. The only sounds may be the wind and, now and then, the call of a distant jackal.

So take a moment where you stand. Feel the temperature of the air, and notice whether the fog still hangs on the hills. Look down at the ground — the gravel, the pale lichen, perhaps a line of small tracks crossing the sand. Everything around you survives on very little. As you move on, watch for the dark shape of a Welwitschia on the plain, and remember that it may have been growing there for centuries before you arrived.
