Table Mountain

Look up, and the city seems to lean against a wall of stone. Table Mountain rises more than a kilometer above the streets and the sea. Its top is not a peak but a long, level line, as if someone had drawn it with a ruler. Clouds often slide across that line and pour down the cliffs like slow water. Locals call this the tablecloth.

The flat summit stretches about three kilometers from end to end. On one side stands Devil's Peak. On the other rises Lion's Head. Together they form a natural amphitheater that holds the oldest part of Cape Town. Sailors in Table Bay have used this shape as a landmark for five centuries.

The stone under your feet is old beyond easy imagining. The pale sandstone of the upper cliffs formed on ancient sea floors, layer by layer, more than 500 million years ago. Later the land rose, and softer rock wore away. What remained was this hard, level slab. The mountain is not a young peak pushed up by sudden force. It is a survivor, left standing while the land around it washed away.

People have named it again and again. The Khoi herders, who lived here long before Europeans arrived, knew it as Hoerikwaggo, often translated as mountain in the sea. In 1503, the Portuguese admiral Antonio de Saldanha anchored in the bay and climbed the great gorge that splits the cliff face. He called the summit the Table of the Cape. His route, Platteklip Gorge, is still the most direct way up on foot.

Most visitors ride instead of climb. The aerial cableway opened in 1929, after decades of failed schemes that included a rack railway. Since 1997 the cars have rotated as they travel. The floor turns a full circle during the five-minute ride, so every passenger sees the cliffs, the city, and the ocean without moving a step. Strong wind stops the service, which is worth remembering before you commit to riding down.

At the top, the air is cooler and the sound of the city falls away. Stone paths cross the plateau between low, wind-shaped shrubs. Viewpoints look north over the city bowl, west to the Atlantic coast, and south along the spine of the peninsula. On a clear day you can see Robben Island, flat and pale in the bay.

The plants deserve a slow look. This mountain belongs to the Cape Floral Kingdom, the smallest and, for its size, the richest plant kingdom on Earth. Around 1,500 species grow on Table Mountain alone, more than in the whole of the British Isles. The local vegetation is called fynbos, an Afrikaans word meaning fine bush. It looks modest from a distance. Up close it holds proteas, ericas, and reeds that grow nowhere else in the world.

Watch for movement among the rocks. The most famous residents are dassies, round furry creatures about the size of a large rabbit. Their closest living relative, strangely, is the elephant. They sun themselves on warm stone near the upper cable station. Bright sunbirds and long-tailed sugarbirds flick between protea heads, chasing nectar.

The true summit hides in plain sight. At the eastern end of the plateau stands Maclear's Beacon, a stone cairn built in 1843 by the astronomer Thomas Maclear, who used it to help measure the curve of the Earth. At 1,086 meters, the ground there is slightly higher than the viewpoints near the cableway. The walk across the plateau takes under an hour each way.

The mountain anchors Table Mountain National Park, which runs down the whole peninsula to Cape Point. In 2011 it was named one of the New Seven Wonders of Nature after a global public vote. For the people below, it is something simpler. It is a compass. If you can see the mountain, you know where you are.

Treat the mountain honestly. Its weather changes fast. A warm morning in the city can turn to cold, wet cloud on the summit within an hour. Hikers carry water and a warm layer, and they tell someone their route before starting. The mountain rewards care.

Before you leave, find a quiet ledge away from the crowds. Below you, the city hums. Beyond it, two oceans meet around a bent finger of land. The stone under your hand was a seabed before there were trees, before there were fish with jaws. It will remain long after every name we give it is forgotten. For a few minutes, you are its guest.
