Tanzania’s section of the Serengeti ecosystem, Serengeti National Park, has fared better because it's so much bigger, ten times the size of the Mara. And it has only half the number of hotels and lodges.
Still, tourism is often is concentrated on a few key areas of the park, and this has resulted in congestion, especially during wildebeest river crossings in the north. (see above photo) Guides are under pressure to please clients, and sometimes don't obey the rules. We learned that a tourist vehicle jockeying for position at a river crossing actually hit a young zebra!
For the Serengeti, the right kind of tourism is high-value, low-density nature tourism. So far, Tanzania has followed this model, and it’s important that it continues. To its credit, Tanzania is seeking to diversify its tourism by promoting other less visited parks and reserves.
This is the renewed challenge as tourism again takes off. We'll be watching as this develops.
