While my brother and sister-in-law were here, we followed a brilliant co-workers' suggestion (THANKS, Annie!) and headed out the Crescent Island, in Lake Naivasha. It didn't originally have any animals on the island, until the filming of Out of Africa when they decided to cart the animals out to the island and then leave them there. Ok, so it's not the most natural of beginnings, but now it's gorgeous! And to hike around amidst the animals...amazing.
