Karon is the second largest of Phuket's tourist beaches at 3 km length, some 20 kilometres from town. Not many hotels have direct beach frontage - most are across the road (which is not a busy one). Therefore practically the entire beach is public. Large resort complexes line the opposite side of the road from the shoreline, but the long, broad beach itself has no development. The sand is very white, and squeaks audibly when walked upon. The southern point has a fine coral reef stretching toward Kata and Bu Island. Also, there is a wide pedestrian / bicycle path on the beachside of the road running the length of the beach.
Most Restaurants, bars, tour companies and other non-hotel businesses are at the north central end, near the traffic circle, or near the south end, on Bangla road connecting the back road with the beach road. Nightlife is pretty much confined to dining and a few beer bars.
The northern third of Karon Beach is essentially undeveloped and flanked by Nong Harn Lake which is the largest beach side park in Phuket offering a nice exercise/jogging/cycling path. North Karon also offers white beach and clear water with no crowds. Karon is arguably the most up-scale of Phuket's beaches.
At the south end of Karon a narrow road between Kata and Karon has a number of small businesses as well as the Dino Park Mini Golf facility. There is a regular daytime bus service to and from Phuket Town.
If coming from Phuket Airport you can pick up a voucher from the airport transportation booth for a flat rate of 750 baht. The drive is just under an hour. Many hotels offer transport from airport to the hotel for 1000 baht.
You can also take metered (yellow) taxis - cheaper than from inside at c. 650 baht. Turn right as you exit the airport building (ignore the touts) and you'll see a stand at the end of the walkway. You tell your destination to the staff at the stand and they will give you a paper with the taxi driver number for you to keep in case you need to report a problem. Fares to other destinations in Phuket cost around 300 baht and up. The rate is what is displayed by the meter plus 100 baht airport fee. The meter will start with a 50 baht display. You may stumble upon a freelance taxi driver that will take you from the Airport to Patong for the flat fee of 400 baht. If the driver is pleasant, you may wish to ask for his mobile number for the return trip later. The same driver can take you from Patong to Phuket Town for 350 to 400 baht.
For those who are price conscious, the transportation booth inside the airport also sells seats on a minibus for 200 baht (nov 2013). The minibus makes several stops along the way to drop off other passengers.
For those who want to save even more, take a near-hourly (see Phuket Town "Airport" listing for actual times) airport bus to Phuket Town (90 baht as of 2014, 1 hour). From there, go to the downtown market (around 1-2 km away, but motorbike taxis will offer you rip-off prices like 40 baht, bargain or wait for a public songthaew), then wait for a bus/songthaew to Karon beach.
Or, at this number one bus station where the Airport buses stop, songteows now go from here to all the beaches because of the extra space created by the opening of the new number two (distance buses) terminal. Cost is about B50 each way.
Probably the cheapest and most convenient way to get around is to rent a motorbike for yourself which is suitable for one or two people. These can be rented at various shops around the island, with one located a few hundred meters to the east of the traffic circle on Patak Road (East). Typical rates run 150(non-automatic) to 200 Baht for automatic shift models. This would allow you to get around anywhere on the island for one flat rate for 24 hours.
Be careful with this though as driving up and down the winding mountain roads is not necessarily for the first time driver. Although all sizes of motorcycles are readily available for rental at reasonable pries, it is not always advisable to do so. Insurance coverage is not available for motorcycles. You must pay for any damages along with any medical bills. If you do choose to rent a motorcycle, please drive carefully. Last year in Phuket alone there were more than 10,000 injuries sustained in motorcycle accidents, with 179 people killed.
Another option to get around is by tuk-tuk or taxi, which are mostly needed to go to other parts of the beach or nearby towns. To get to Phuket Town taxis are available and cost around 400 baht. There are also public buses(Songthaews) which leave from Karon to different places every hour for around 20 baht.
Karon - Patong will cost you 300 baht per tuk-tuk ride - though if you keep moving through the drivers you will eventually find one for 250. (The local tuk tuk mafia seem to have stitched up the prices.) From Patong - Karon Beach should be cheaper as there are a lot more tuk-tuk trying to pick up passengers.
Unlike the bigger, busier, and noisier Patong further north, Karon offers visitors a nice long quiet stretch of sand, with plenty of beach umbrellas available for rent. Facing west, it gives a beautiful view of the sunset.
Dinos Park Mini Golf (ไดโนปาร์คมินิกอล์ฟ) Dinos Park Mini Golf is located beside the Marina Phuket Resort, Hat Karon. This 18-hole mini-golf course in a primitive atmosphere uses the light and sound techniques to feature dinosaurs and an erupting volcano. It is open daily from 10.00 a.m. – 12.00 p.m. Admission is 120 Baht. Green fees are 240 Baht for adults and 180 Baht for children. Tel. 0 7633 0625, Fax: 0 7633 0516.
