Here's some info about Phuket:

Phuket is the largest and most popular island in Thailand . 48 km long and 21 km wide, situated in south Thailand , on the west cost of Thailand , in the Andaman sea. The island is connected to Thailand with a bridge, and therefore you can go from Bangkok to phuket also by bus or by car, but most tourists prefer to reach phuket by flight (about 1.5 hours from Bangkok and 2 hours in direct flight from chiang mai).

Phuket district is full of beautiful scenery. The island contains mountains and forests as well as beautiful white sand beaches, and turquoise water. Phuket has a wide range of tours and activities to offer such as: rafting, atv in phuket forests, cable slide in the forest, diving, speed boat to the surrounding islands, cruise to to phang nga area where you can see the huge lime stone rocks coming out of the water, view points over phuket beaches, and of course night life.

Phuket has many accommodation options from exclusive and expensive hotels and resorts to cheap and comfortable guest houses. There are some famous beaches, different from one another:

Patong beach: suitable for singles. Patong beach has the busiest night life: parties, disco, pubs, restaurants, etc. which are mostly concentrated around the famous (some say infamous) bangla road. There are many hotels in Patong Beach, as well as guest houses suitable for backpackers.

Karon beach: this is a more quite beach than patong. More suitable for families and couples, and less for singles. However, in this beach you can also enjoy restaurants and pubs. Most of the beach is occupied with Hilton hotel and tavorn palm beach resort. a bit more to the north, there's the Aroona Plaza which houses some good restaurants and cafes, a few pubs and a hotel.

Kata beach: a bit south of karon beach. Attracts mainly families especially because of its white beaches, clear water, and palm trees. U may also find some good restaurants there, but no night life.

Kamala beach: north of patong beach. A very quite and peaceful place, surrounded by forested hills. Due to its relaxed atmosphere, the beach is more popular with retirees and long term visitors staying in small hotels, villas and apartment rentals nestled around the village

There are other beautiful beaches which are worth visiting even for few hours like: bang tao, surin, pansea, lame singh, emerald beach, paradise beach, nai harn, cape panwa and more.
