Hi Karlomarx
There is lots of great diving in Thailand particularly on the Andaman Coast, some of the best diving can be found in the Similan Islands however, a lot of the sites there are advanced, deep or prone to strong currents. The best way to see the Similans is to go by Liveaboard.
If you're looking for a good place to learn with excellent diving you should consider Koh Phi Phi. Just an hour by ferry away from Phuket the marine park is host to divers from Krabi, Ao Nang, Koh Lanta and Phuket. However from all these destinations it's 2 hours by boat.
If you want to dive phi phi the best option is to stay on Koh Phi Phi Don, just 15 minutes away from the marine park.
Phi Phi Don is a beautiful island with hotels, restaurants and many activities such as diving, sea kayaking, rock climbing, diving, snorkelling and trekking.
The National Marine Park of Koh Phi Phi Ley and the Bida Islands offers diving for those of all levels, maximum depths ranging from 20 to 30m and perfect for beginners and advanced.
The dive sites are easy and vibrant and play host to marine life such as lionfish, seahorses, clownfish, leopard sharks, black tip reef sharks, bamboo sharks, Turtles and the occasional visit from Whale Sharks, Bull rays and Eagle rays.
With Blue View Divers we offer exploration of the islands above and below water. Late starts on our custom handmade traditional thai longtail boat allows us to access sites and beaches big dive boats cannot. Also we offer flexible courses with in pool training.
