The smallest number of people required on some tours is two. ……………….. 10. Children can join the Mount Kilimanjaro trip from the age of ten. ……………….. THE TRIP OF A LIFETIME Take a trip to East Africa. You begin this trip by visiting the wonderful wildlife parks. As well as travel by coach, there is also an opportunity to take a short trip in a hot-air balloon over the parks to get a better view of the wildlife. After visiting the wildlife parks you have the choice of either spending the rest of your holiday (7 nights) climbing Mount Kilimanjaro - the highest mountain in Africa - or, for the not so adventurous, sunbathing on the beautiful white sand beside the Indian Ocean. (It is also possible to stay an extra week at the coast). Day One: Fly from London Heathrow to Nairobi, Kenya. Day Two: Drive to the National Park at Lake Manyara. This park is famous for the large variety of birds, which you can see there early in the morning. Day Three: Leave Manyara for the Serengeti National Park, where you may see elephants, lions and giraffes. Days Four to Nine: Spend these days travelling by coach around the park. All visitors have a window seat on the coach with a clear view for photographs of the park and animals. Although the animals are not worried by tourists taking photos, we ask visitors to speak quietly so as not to disturb them too much. Accommodation in tents is normal in the parks. All have private washing facilities. The tents have plenty of space, are very comfortable and have a solid floor. The guides are highly experienced, but there is always the possibility that you may be very unlucky and not see certain animals. Day Ten: Departure for the mountain trek or to the Indian Ocean. The Indian Ocean Hotel is on the beach and all rooms have air-conditioning and sea views. All water sports are available and there are tennis courts, which you can use free of charge except during high season, when there is a small booking fee. No special skills are needed to climb Mount Kilimanjaro, but if you choose this trip you must already be fit and healthy and ready to accept some very basic accommodation in mountain huts. Most tours and safaris can only operate with a minimum number of passengers. If this number is not reached, we might cancel the tour. If this happens, we will make a decision at least 8 weeks before departure and will try to arrange a different holiday. Minimum numbers can be from 2 to 15 according to the tour. For practical reasons, children under the age of 8 (under 12 on climbing holidays) may not be accepted on certain tours.
