Lamu is absolutly an amazing little nice wild place! You can get there practicly only by a small plane landing in a short dirty road than sail to the village that's over the sea. If you like the paces where there is no energy, no fridges, no ice, no hospital, ho hotels, NO CARS, no turists, nothing but old walls and nature with some mens than you'll simply LOVE it! What to do there?...nothing but walk around and enjoy the absence of modern life... I've been there my first time when I was 12 with my grandpa and we had absolutly no problems so I beleave it's a safe place where to go. Yust logically respect their traditions. The sea is not nice to swim. The food is fine. Pay atteantion to the water you drink. To sleep look for local accomodations. I've been in the Lamu Hause...I really suggest it! It's WONDERFUL!
