Safari Parks
A safari park is like a large zoo, where the animals live in natural conditions. There are several safari parks in Britain and they are very popular places for visit. One of the most famous is at Windsor, which is close to London airport.
You can visit some parts of the safari park on foot. Here you can see the animals that are not dangerous, like giraffes, zebras, camels and antelopes. The animals walk around as if they were in Africa.
But safari parks also have lions, tigers, leopards and other dangerous animals. These cannot be kept with the other animals, because they would eat them. They would also eat the visitors, so they have to drive through the parts where animals live. You have to keep your windows closed and you must not get out of the car. It is not a good idea to take a new car into this part of the park, because the monkeys climb on the cars. They often scratch the paint and they sometimes pull aerials and windscreen wipers off.
Safari parks are much better than ordinary zoos, because the animals do not have to live in small cages.
