Phuket is one of the region's economic powerhouses—millions of tourists visit the island every year, enjoying the many delights that are offered in this established resort island. Phuket is a modern, vibrant island with more than 6 million annual visitors, a number that is only increasing year-to-year. If you've never been to Phuket, you will likely love it; returning visitors will find a new island that eagerly greets its next wave of tourism. Koh Phuket is linked to the mainland by a causeway, and the rest of the world by an international airport. Its indented coastline and hilly interior make the island seem larger than its 48-km (30-mile) length and 21-km (13-mile) breadth. Before tourism, Koh Phuket was already making fortunes out of tin mining and rubber plantations. Then backpackers discovered Koh Phuket in the early 1970s. Word quickly spread about its white, sandy beaches and cliff-sheltered coves, its plunging waterfalls and impressive mountains, its cloudless days and fiery sunsets. This love of Phuket has brought serious problems. Entrepreneurs built massive resorts, first in Patong, then spreading out around the island. Before the tsunami there was no easy way to navigate the island, which was plagued by horrendous traffic and overdevelopment. Some would say Phuket was being loved to death. Now visitors may be taken aback in some parts by ongoing overdevelopment, but there are also places where you can isolate yourself from the rest of the island. Even though it may seem like every other business here is a tour operator or dive shop or tailor or jeep rental or pub, there's a lot to love about the island. The beaches are still beautiful, and this remains a top destination for snorkeling and diving (with more than 180 registered dive shops). The island offers some of the most exclusive resorts and spas in the world, yet the food, drink, and accommodations are cheap compared to most visitors' home countries (though Phuket is quite expensive by Thai standards).
