Jakarta practically straddles the equator, and the climate is hot and steamy year-round. A great way to cool down and have fun is an afternoon at a water park. Affiliated with Waterbom Bali, Waterbom Jakarta opened in late 2007 on a once-marshy patch of North Jakarta. It's green and shady, with more than 15 waterslides. Thrill seekers get an adrenaline rush on the fastest slide, which sends riders down its slippery slopes at about 70km an hour. Avoid packed weekends and school holidays.
