Travelling to Hawaii with my friends was more than just a fun experience; Hawaii actually teaches you to challenge your physical conditions, and learn a little about yourself. The Diamond Head mountain requires the maximum physical effort. While you are climbing, there's very little shade, but when you get to the top you can enjoy wonderful views. The climb is best made early in the morning or at dusk, as there are plenty of tourists. Be sure to take good shoes and plenty of water, and don't forget your camera.
