After a while being in Kenya we decided to explore the Tsavo National Park. Eventually, after the first rushed trip that gave us a feel for the area, we returned to both Tsavo East and West in several opportunities.
The journey to either of the two park sections was very picturesque as the Mombasa road follows the Athi river with the Yatta plateau, the world’s longest lava flow (290km) that runs along the road and also forms the western boundary of the park. On clear days Kilimanjaro could be seen towards the southwest and then the Chyullu hills (to which I will return later on when dealing with Tsavo West) will make an appearance on the right.
Tsavo National Park was gazetted as a wildlife reserve by the Kenya colonial government in 1949 despite not being the best wildlife area in Kenya but by virtue of being an area of arid scrub too dry for agriculture and, being infested by tsetse flies -vector of trypanosomiasis- also unsuitable for livestock and, largely without human habitation.
David Sheldrick became its first Warden and, apart from dealing with the problem of armed poachers, he developed the original infrastructure of the park while studying the elephants’ behaviour and food needs, and, with his wife, Daphne, rescuing and hand-rearing vulnerable elephants, rhinos and antelopes. After his premature death Daphne established the David Sheldrick Wildlife Trust in his memory that runs the well-known Elephant Orphanage in Nairobi.
The park occupies 22,812 km² of the 41,000 km² of the original Tsavo ecosystem, 13,747 km² and 9,065 km² for the East and West sections respectively . At its inception it was rich in wild animals with about 45,000 elephants and 8,000 black rhinos. Regrettably, after its creation, pressure from the climate and the surrounding human population interfered with elephant movement and brought about a gradual loss of the woodlands due to the high numbers of elephants and the area was transformed into grasslands, good for other species but less so for browsers like rhino and elephants.
“The deeper the white man went into Africa, the faster the life flowed out of it, off the plains and out of the bush…vanishing in acres of trophies and hides and carcasses” wrote Peter Beard in his now classic book “The End Game” that highlighted the Tsavo crisis and that anyone interested in nature should look at and read .
So, a severe collapse of the elephant and rhino population followed, particularly the black rhinos. By the time we started going to Tsavo the black rhino had already banished. There were rumours that some had sought refuge in the most remote areas of the park but we never saw any.
I will deal with the two parts of the park separately (starting with Tsavo East) as they both offer their own interesting features.
Tsavo East National Park
Usually we entered the park at the Manyani Gate and travelled through it on our way to the beaches in the Indian Ocean. Sometimes we stayed at the National Parks’ accommodation at the Aruba dam when we were late to complete the traversing of the long distance inside the park.
Before you reached the Manyani Gate we travelled through the territory where once the man eaters of Tsavo ruled. Two lions stopped the construction of the railway in the Tsavo River for nine months and killed more than a hundred workers since March 1898. “The Man-eaters of Tsavo” written by Lt. Col. John Henry Patterson, who was in charge of the work and shot them, is a fascinating read! 
In his book Patterson wrote: “. …Two most voracious and insatiable man-eating lions appeared upon the scene, and for over nine months waged an intermittent warfare against the railway and all those connected with it in the vicinity of Tsavo. This culminated in a perfect reign of terror in December 1898, when they actually succeeded in bringing the railway works to a complete standstill for about three weeks… Their methods then became so uncanny, and their man-stalking so well-timed and so certain of success, that the workmen firmly believed that they were not real animals at all, but devils in lions’ shape…”
We came face to face with some of the man-eaters but they presented no danger to us as they had been stuffed with straw for years at the entrance of the Muthaiga Country Club in Nairobi.
Before arriving to the Manyani Gate we usually stopped for re-fueling at the Man-eaters’ Motel stop where there was a memorial that commemorated the event. It was precisely there that I had my life-threatening encounter, not with a man-eater lion, but with a huge baboon that snatched my packet of crisps! .
Once you turned at the Manyani Gate the road was rather monotonous until you arrived at the Galana river where we usually stopped to look at the Lugard falls where the river passes through volcanic rock, carving a narrow path that had created a series of rapids and falls as the water flows faster. It was named after Frederick Lugard , who passed this place on his way to Uganda.
Most of the times we continued following the river towards the coast (a more interesting drive than the usual way via the Mombasa road) but, a couple of times we deviated south towards the Aruba dam, built in 1952 across the Voi River, a reservoir created to provide water to the game and birds. There we spent a few nights during which we found it difficult to sleep because of the noise the elephants made while coming to drink.
Tsavo East is a good place to see fringed-eared oryx grazing on the open plains. The very shy lesser kudu could also be spotted during the early morning when they were away from the thicket. Rarer still was the finding of the long-necked gerenuk standing on its hind-legs to reach the sparse foliage of trees and bushes in the arid environment.
Although there were still elephants at the time of our visits, they were “diluted” because of the size of the park. For the same reason lions were also difficult to bump into. However, when you did you were in for a surprise as the males were maneless  and probably its ancestors were of the man-eating variety!
The “baldness” in these lions is attributed to an adaptation to the thorny vegetation in the park as their hair could interfere with their hunting. As their colleagues in Tsavo West that live in a similar environment have normal manes, I personally believe that their baldness, as in humans, is due to high levels of testosterone that may also explain its aggressive reputation.
 As a comparison, the Kruger National Park has an area of 19,485 km².
 Lt Col. J. H. Patterson in Chapter II of his classic book “The Man-eaters of Tsavo and Other East African Adventures”, published by MacMillan and Co. Limited, London in 1919. If you are lazy, you can ruin a good read and watch the 1996 Hollywood-style movie “The Ghost and the Darkness” (Paramount) with Val Kilmer and Michael Douglas.
