Question

There are many places to go on safari（观赏野生动物）in Africa，but riding a horse through the flooded waters of Botswana's Okavango Delta must rank as one of the world's most exciting wildlife journeys．
Several safari camps operate as the base for this adventure，providing unique rides twice a day to explore deep into the delta．The camps have excellent horses，professional guides and lots of support workers．They have a reputation for providing a great riding experience．
The morning ride，when the guides take you to beautiful，shallow lakes full of water lilies，tends to be more active．It is unlike any other riding experience．With rainbows forming in the splashing water around you and the sound of huge drops of water bouncing off your body and face．It is truly exciting．You are very likely to come across large wild animals，too．On horseback it is possible to get quite close to elephants，giraffes and many other animals．The sense of excitement and tension levels rise suddenly though，as does your heart rate，as you move closer to them．
In the evening，rides are usually at a more relaxed and unhurried pace．With golden light streaming across the grassy delta and the animals coming out to eat and drink．Sedate though they are，rides at this time of day are still very impressive．As the sun's rays pass through the dust kicked up by the horses，the romance of Africa comes to life．
Back at the camp you can kick off your boots and enjoy excellent food and wine．Looking back on your day，you will find it hard to deny that a horseback Safari is as close as you will ever come to answering the call of the wild．
