The biggest island in the Gulf of Thailand, Koh Samui is ideally placed close to the stunning Ang Thong Marine Park and main dive sites of the area. With its white sand beaches lined with palm trees and inner jungle to explore, diving Koh Samui is a perfect holiday destination for people after a holiday which includes a bit of everything.
The diving near Koh Samui can give divers of all levels amazing experiences with the chance of seeing Green Turtles, Hawksbill Turtles, Whale Sharks, as well as smaller life such as banded sea snakes, moray eels and an abunadance of reef fish.
Koh Samui has a artificial reef structure project taking place on the north shore. Broken coral is collects and then attached to a structure will a low current running through it which helps stimulate the corals regrowth. Hopefully in the future this technique will enable the healing and replacement of a lot of destoyed and damaged reefs around the island.
The climate in this area is tropical so although most of the year is it lovely, hot beach weather it does have a monsoon season. This is from the end of October to the beginning of December. During this period the temperature drops and there is heavy rain most days with strong winds which can cause flooding and loss of electricity. Obviously dive operators close during this time tend to close as the seas are very rough and it’s inadvisable to dive, so the dive season runs from late December to late October.
Water temperature can vary from 27C-31C with the coldest water temperature being during and either side of the monsoon in October and December. The sea warms up until it reaches its highest point around May and then slowly drops down again towards October. The coldest points of the season, when the water temperature has dropped to around 29C, are the best times of the season to see sharks, as when it’s at its 31C peak the water is to warm, so they migrate elsewhere until the temperate drops back down.

There isn’t much shore diving around Koh Samui as most of the reefs have been destroyed or polluted with bad visibility. Chaweng Beach can be dived as a shore dive and is the main option for those wishing to night dive from Samui. You can see lots of little critters that aren’t out during the day as well as many crabs and many even some squid.

The beaches are all very shallow and easy dives so can be undertaken by any levels. The main thing to watch out for on Samui’s shore dives are reckless jet skiers so its important to have a person on the surface watching your bubbles and to also surface under a Surface Marker Buoy.
Most of the sites visited are closer to Koh Tao and are accessed on day speed boats which tend to leave Koh Samui at 8.30/9am and arrive back around 3pm. These all provide lunch in between dives which is usually taken one of Koh Tao’s beautiful white sand beaches.
Diving around Koh Tao caters for all levels of experience from beginners to experienced as there is a range of dive sites from easy shallow shore dives such as Mango Bay to deeper sites like Chumphon Pinnacle. Mango Bay is a typical beginner dive which has a sandy gently sloping bottom and plenty of marine life including a huge shoal of fusiliers which can reliably be found every dive. Chumphon is a much deeper pinnacle offshore which can have strong currents but also the chance of Whale Sharks in season. This site isn’t for beginners but is an excellent advanced deeper dive if the currents aren’t too strong.

The other main dive site of the area visited from Koh Samui is Sail Rock which is a rocky pinnacle just north of Koh Pha Ngan. This site is a must dive for anyone in the area, not only does it have colourful coral gardens and steep walls dropping off to 30m plus, but it also includes a swimthrough called the chimney and regularly has big schools of trevally, fusiliers, batfish and barracuda! To top it off it is also one of the best places in the area where you are most likely to spot the elusive whale shark!

Koh Samui is the most accessible of the 60 islands in the gulf of Thailand as it is the only one with an airport with frequent flights to and from Bangkok and Phuket and also a direct ferry service from the mainland. This makes it a very low hassle destination and also a perfect stopping off point to journey on to some of the more remote islands in the area such as Koh Tao. Thailand has a months visa upon arrival for most countries but it is best to double check in advance with the embassy.

Chaweng Beach is the main tourist hub of the island with a huge selection of beachside bars, restaurants and also many nightclubs. This does mean it can get very busy during the peak holiday season but luckily there are many other quieter options around the island. Some of these are the Fishermans Village on the north side of the island, near Bo Phut, which has an excellent selection of restaurants and shopping and there are also some nice little restaurants in some of the bays such as Silver Beach and Ban Taling Ngam.

Diving at Koh Samui doesn’t just offer an easy location to base your dives from, there is a lot more to see and do. This makes it an ideal location to visit with family or friends that don’t dive or want a dedicated diving holiday. Some of the other activities range from a day trip to Ang Thong Marine Park, where the book “The Beach” was set and has jaw dropping scenery, Elephant rides, jungle tours, stunning waterfalls, many white sand beaches lined with palm trees, cheap shopping, markets and even the slightly different activity of shooting some guns and sniper rifles at a shooting range.

Thai vendors can sometimes make some people feel uncomfortable. They can approach you with goods to buy or to persuade you to enter their shops or restaurant. A calm and clear, “No, thank you,” will usually do the trick.
Motorbike accidents are very common, so ensure you wear a helmet and do not drink drive! Most roads on the island are only dirt roads and are not recommended unless you are an experienced rider. If you do hire a motorbike bear in mind that although the vehicle hire shops are cheap it can be very expensive paying for scratches on the newer bikes, so try to hire an older bike.
Koh Samui has a couple of hospitals and also has a recompression chamber.
Koh Samui is where i worked as a DM in training :) Had some excellent dives during that time around Koh Tao and Sail Rock. Although i was slightly early in the season for Whale Sharks, which arrived a few weeks after i left! i still had some very fun enjoyable dives with plenty to see.
Loved the huge schools of trevally numbering in their thousands that swirl around completely engulfing you at Secret Pinnacle just off Sail Rock, also the huge schools of batfish, barracuda and fusiliers! Will definitely be back to re dive Sail Rock......next time in the Peak Whale Shark time! :)
