Don't go to Kauai. Go to any of the other Hawaiian Islands --- Maui, Lanai, the Big Island --- but leave Kauai for us. The weather on Kauai is so unpredictable (不可预测的) that sometimes it rains all day --- in fact, it's the second-wettest spot on the earth. Yes, there are giant double rainbows all the time, and the sunlight through the clouds is magical. But if you are not interested in these, go somewhere else. You just can't control the nature on Kauai, and who wants to surrender (屈服) to the nature when you could be at a fine hotel, lying in a comfortable chair next to a swimming pool, with food served upon request?

So what if Kauai produces surf champions the way Texas produces cowboys?Most of its 300 white-sand beaches are unmarked. Unless you connect with the local people, the hidden spots are hard to find. While Hanalei is the most beautiful town you've ever dreamed of, you can forget about discos and clubs. Worse, it doesn't have one single four-star restaurant. What it does have is the original drive-through places where you pass by a rambutan tree (红毛丹树), and pick a piece of fruit.

Shopping in Kauai? Forget it --- unless you are interested in shell necklaces and beautifully carved wood bowls. Kauai is not about pampering. It's about going natural and finding the nature within you. It's a do-it-yourself place that offers walking along the coast, diving and swimming in the Pacific Ocean, and lying on the beach.

Don't go to Kauai unless you have a lot of time, because there's only one road, which can be slightly dull. It winds through the beautiful scenery of waterfalls, rivers flowing into the ocean, and taro (芋头) fields. You have no choice but to look at everything, because the speed limit is 35 m.p.h.

If you're not interested in color, don't bother with Kauai, because that's what you get --- red roads, blue oceans, and a hundred different shades of green. It's like diving on land. Many people on Kauai believe that this is Lemuria --- a lost island in the Atlantic. Can you imagine? Those Hawaiians, surfers, New Agers, and people who love nature and beauty and want a different quality of life --- what do they know, anyway? Forget about it --- you're not going to like it. Go somewhere else. Leave Kauai for us.
