Lake Challa, in the Amboseli region, is supposedly a safe place to swim, but an 18-year-old British student volunteering on a five-month environmental mission was killed by a crocodile there March 8. According to the company running the expedition, the hotel where the group was staying, a guidebook and some locals who were asked, the lake is a good place to swim. Police, however, stated that the lake is infested with crocodiles. If in doubt about the safety of bodies of water, obtain as many opinions as possible, and consider entering the water only where the locals do.
