The Masai Mara is one of the best known and most popular reserves in the whole of Africa. At times and in certain places it can get a little overrun with tourist minibuses, but there is something so special about it that it tempts you back time and again.

Seasoned safari travellers, travel writers, documentary makers and researchers often admit that the Masai Mara is one of their favourite places. So why is that? Perhaps it is because of the 'big skies', the open savannahs, the romance of films like 'Out of Africa' and certainly because of the annual wildebeest migration, the density of game, the variety of birdlife and the chance of a hot air balloon ride.

Also because of the tall red-robed Masai people whose lifestyle is completely at odds with western practices, and from whom one learns to question certain western values.

A combination of all these things plus something to do with the spirit of the place - which is hard to put into words - is what attracts people to the Mara over and over.

The Masai Mara lies in the Great Rift Valley, which is a fault line some 3,500 miles (5,600km) long, from Ethiopia's Red Sea through Kenya, Tanzania, Malawi and into Mozambique. Here the valley is wide and a towering escarpment can be seen in the hazy distance. Most of the game viewing activities occur on the valley floor, but some lodges conduct walking tours outside the park boundaries in the hills of the Oloololo Escarpment. The animals are also at liberty to move outside the park into huge areas known as 'dispersal areas'. There can be as much wildlife roaming outside the park as inside. Many Masai villages are located in the 'dispersal areas' and they have, over centuries, developed a synergetic relationship with the wildlife.

There are four main types of topography in the Mara: Ngama Hills to the east with sandy soil and leafy bushes liked by black rhino; Oloololo Escarpment forming the western boundary and rising to a magnificent plateau; Mara Triangle bordering the Mara River with lush grassland and acacia woodlands supporting masses of game especially migrating wildebeest; Central Plains forming the largest part of the reserve, with scattered bushes and boulders on rolling grasslands favoured by the plains game.

The other night the Discovery had a documentary that took place on the Masi Mara National Reserve. It looks like a great national park, but it has had problems with poachers coming in and hunting down endangered wildlife. I have thought about taking a vacation there soon because I am concerned that some of the wildlife will become extinct.
