Crescent Island Game Sanctuary
The only way to get here is by boat, past kingfishers and pelicans, from one of the lakeshore hotels to Crescent Island Game Sanctuary, where you can see (and walk with) giraffe, zebra, and other plains herbivores; there are no predators so it's quite safe. On the way to the crater keep your eyes open for hippos as you are on the outer rim of a volcanic crater, which is also the deepest part of the lake.
