Diving in Samui is definitely one of the attractions of the island. Ko Samui has some beautiful dive sites. The conditions for this underwater activity are great all year round. However, during the months of October to December, the weather is often windy so the visibility underwater may not be that good. The best months to dive are May to August.
Your diving activities can be pre-arranged by your travel agency or the resort where you are staying. You may also look around for diving schools once you get to Ko Samui because these often offer diving trips. They also have diving equipment for rent.
If you don’t know anything about diving and have a bit of time to spare on your trip, you can enroll in a quick diving course. Make sure you choose a diving school whose instructors are certified by the worldwide Professional Association of Diving Instructions or PADI. One thing is sure: whether you are a beginner or an advanced diver, you will find some ideal diving sites suitable for your skills. The reef areas in Ko Samui are actually ideal for beginners. More advanced divers can head out to the diving areas near the island.
One advantage of diving in Samui is that the area offers good access to other wonderful sites in nearby areas, such as the Angthong National Marine Park, Sail Rock, and the Koh Tao diving areas. Angthong National Marine Park is located northwest of Ko Samui and consists of more than 40 islands including Koh Tao and Koh Yippon, which are frequented by divers.
Koh Tao waters can reach up to 20 meters deep. They are home to the famous Table Coral Formations. Common sightings in these waters are beaked coral fish, blue spotted rays, angel fish, and turtles. The neighboring Koh Yippon is a smaller island with waters also reaching 20 meters deep. It has beautiful colorful coral gardens as well as turtles, angel fish, fusiliers, banded sea snakes, and porcupine fish.
Sail Rock is found 45 kilometers off the northern coast of Samui. It is considered as the best diving site in all of Thailand. It has magnificent underwater formations such as the chimney-shaped vertical swim-through. It also has extensive coral gardens and various sea animals including yellowtailed barracuda, wrasse, white-eyed moray eel, giant grouper, cleaner shrimps, and the cowrie shell.
If you wish to explore the underwater scenes but don’t have the confidence yet for diving in Samui, you can opt for snorkeling instead. Snorkeling may be limited to the shallow waters near the island, but it will afford you an amazing way to see the variety of colorful fish and corals that inhabit Ko Samui waters. You can buy snorkeling gear in the supermarket or you can rent them from most diving schools, where you can also have your trip scheduled.
When you go diving in Samui, remember not to touch or gather corals, shells, and other sea animals so as not to disturb the marine environment. These animals are not to be collected as souvenirs.
