We also visit the second largest canyon in the world and the largest in Africa, as well as the most visited tourist attraction in Namibia. The Fish River has some of the most impressive geological phenomenon with the rocky floor of the Fish River Canyon estimated to be 1 800 million years old. We will walk around with the tourists and observe the natural splendor. The Fish River is the longest interior river in Namibia, but its flow now is a puny trickle compared with the immense volume of water that poured down its length in ages past. It cuts deep into the plateau which is today dry, stony and sparsely covered with hardy drought-resistant plants such as succulents. The river flows intermittently, usually flooding in late summer; and when it ceases to flow it becomes a chain of long narrow pools on the sandy rock-strewn floor of the chasm. At the lower end of the Fish River Canyon .The Fish River Canyon area has a typical semi-desert climate. During the hot summer months (October - March) temperatures can rise to 48°C during the day and cool to about 30°C at night. Relief from the heat comes in short spells with occasional thunderstorms. The average annual rainfall in the canyon area is 100mm. During the short winters, temperatures can go below zero at night, but quickly pick up during the day to a moderate 20 to 28°C.
