【简答题】
You often hear people refer to Africa as a country, not a continent. It is often a region that is described as being unified around poverty, disease and despair. Africa is far from being a homogenized continent. It has more than 50 countries, each with unique culture, landscape and tradition. Africa’s diversity is apparent to anyone who travels to the continent. In the north, you have countries like Morocco, Algeria and Egypt, which have a long tradition of welcoming visitors. Further south there is Kenya and Tanzania, both renowned for their wildlife and for Africa’s tallest peak, Mt. Kilimanjaro. On the southern tip of the continent is South Africa, the region’s economic and political superpower which in itself lies many fascinating cultures. There are also the trouble spots like Congo and Sudan which are almost all but avoided by travelers. Travel in Africa can be rough. It can also be a great joy. If you have patience, a willingness to maintain an open mind, a desire to explore and the ability to laugh at the strange, your African travels will change your life. There are many entry points to Africa. Your best bet in terms of cheap airfare is to fly into one of the bigger cities like Johannesburg or Nairobi. Depending on where you are starting from flights to Africa can be either quite cheap or outrageously expensive. As is true nearly everywhere, flying into the biggest cities is usually your best bet for a cheap ticket. Many people who travel to Africa prefer to do so in a group or through an organized adventure trip. This is especially the case with safari trips. BootsnAll has some of the best African adventure trips and safaris in the world. We work closely with local tour providers to offer you many options at very affordable rates.
