Chaweng is the largest and most popular of Samui's beaches, and is usually divided into three sections: North Chaweng, Central Chaweng and Chaweng Noi (Little Chaweng) around a headland to the south. Chaweng Beach is the longest beach on Samui Island's east coast. The beach is beautiful here and local developers are finally cleaning up some of the trashy areas on the island. It attracts many young travelers and families alike, but still remains good value for money.
The beach is approximately 7 km long with powdery white sand. It is bordered by emerald-blue waters and a coral reef where waves break, leaving the bay quite peaceful. Not far from the beach, there are two small islands near the reef. After swimming, you can explore the nearest one by walking through shallow water or go for snorkeling and kayaking at the second island which is further out and larger.

The central part of the beach is a bit more crowded than the quieter north. Many vendors pass by, offering beverages, fruit, ice cream and local Thai food for the more daring. A variety of local crafts and Thai souvenirs are also available.
The beach itself is usually accessed through the hotels, as there are no beach roads to disturb the peacefulness of the area. It is very relaxing but noticeably more touristy during the high season. The water is clean with usual temperatures between 25-28°C.
Parallel to the beach, clustered in the middle of the strip, lies Samui's greatest concentration of restaurants, bars, souvenir shops and of course, fast food and convenience stores.
Chaweng is a few minutes' ride south from the airport. If you book a taxi at the airport transport desk, it will cost 400 Baht. A shared van (usually requiring 5 passengers before it will depart) will cost 120 Baht per person. Taxi drivers rarely use taxi meters here. If you decide not to use the booking desk, negotiate the fare in advance with the taxi driver. It should cost from 200-400 Baht. Or you may book a transfer with your hotel. This service usually costs 300 Baht, though some of the higher-end hotels have quoted rates of 400 Baht per person.
You may opt to take other, more adventurous forms of transportation like the following:
Motorcycle taxis are ordinary motorbikes and you sit behind the driver during the ride. Depending on the distance, the price ranges from 30-150 Baht.
Motorbike Rentals are available if riding solo is what you prefer. Most motorbike rentals in Chaweng offer 100-125 cc bikes such as Honda Wave, Honda Click, Suzuki Step, etc. Rentals cost 100-200 Baht per day depending on the length of the rental.
Bigger motorbikes like Harley Davidson and sport bikes like Kawasaki Ninja and Honda CBR are also offered. Be warned that bike accidents tend to be a regular occurrence in Ko Samui, so drive carefully.
If you are travelling in a large group, you may opt to rent a jeep. The rental usually costs at least 800 Baht per day. A private car will set you back 1500 Baht or more every 24 hrs. There are many models to choose from: Honda Jazz, Isuzu Hi-Lander, Toyota Camry, Toyota Fortuner, etc. Established rental companies such as Avis and Hertz also offer insurance. It might be a good idea to get the insurance along with the rental as having no insurance during an accident could be expensive.
Almost all activities are on the beach (even parts of the nightlife) and most Samui dive shops are based in Chaweng. It's also the base to arrange trips to nearby Ko Tao and the Angthong National Marine Park.

There are lots of souvenir shops around town. It is not uncommon for the shopkeepers to ask 5 times the normal tourist price particularly in the central areas. Bargaining is always possible when it comes to souvenir and souvenir-like products. Even when a price is indicated a discount up to 50% might be available. As many shops and the often cheaper market stalls sell mostly the similar products ask at several places to get an idea of what is a reasonable price before starting haggling for the product you really want. The clothes sold here can often be found at Khao San Road in Bangkok for a lower price.
On the beach, vendors will sell beach clothes, jewelry, beach toys and games, and food (coconuts, sliced fruit, satay, roasted corn, ice cream, water, etc.). Be prepared to bargain. Most food items are generally 50 baht/piece. They vendors will not bother you if you ignore them or say no.
In the evening several restaurants offer seafood on the beach. Almost all hotels offer dining at the beach so compare prices.

Chaweng is the heart of Ko Samui. The once abundant backpacker bungalows and hostels are virtually non-existent and have been replaced with newer, more modern and obviously more expensive tourist orientated hotels. Always insist to see the room before you book in any hotel if you choose one of the more affordable hotels. Be aware that the nightclub district is not far from many of the good beach hotels, which tend to be on the north half of Chaweng. This is fantastic if that is what you want on your holiday but not suitable for the quieter more romantic holiday.

Your guesthouse and many other places in town can rent you a motorbike for between 150 to 200 baht a day to head around the island on your own. Bicycles are a bit harder to come buy but are also available for about 100 baht per day. As the traffic is left-sided you should be very careful (and wear a helmet) while driving even if you are familiar with driving on the left, other road users might not. Accidents, sometimes with fatalities, are too common despite the light traffic.
Travel Agencies can sell you bus tickets with pick-up from your hotel and including the ferry to many destinations in Thailand such as Bangkok, Phuket, Krabi. Booking the same tickets in Nathon or for trains at the Surat Thani station works out to be significantly cheaper sometimes.
