Mainland Malaysia is located between Thailand and Singapore, with Malaysian Borneo and Indonesia each having land and sharing a border on the large island of Borneo. The Equator runs directly though these areas, so the country is covered in lush tropical rainforests and has dramatic landscapes of mountains with backdrops of sea. Along with the crystal clear waters around the islands themselves, Malaysia is an amazing destination for just relaxing on the beach, travelling to remote caves and mountains in the jungle, or scuba diving the rich waters of the country.
The best diving in Malaysia is concentrated around the coast of Malaysian Borneo, in places like Sipadan National Park and Layang-Layang. These destinations are well known for their profuse sea life and pristine coral reefs. The Malaysian government protects these islands year round, and limits the amount of divers for each area. So permits must be obtained to be allowed to dive there, and this is the responsibility of the dive operators to organize, so guests do not need to worry about these things.
Layang-Layang is a hot-spot for hammerhead shark action, especially from late March to early May, huge schools can be seen in the shallower parts of the reefs, above 30 meters. And because the island is essentially a military base, the area receives constant protection from poachers and fishing vessels, even during the monsoon season. Sipadan is well known for it's huge numbers of sea turtles which use the island as a nesting site; along with the famous tornado of barracuda and big-eyed jacks which hand on-top of the reef and can be seen year round. Divers also can see many reef sharks like greys and whitetips, but also in the earlier months of the year hammerheads have been spotted.
The monsoon season for Borneo is from November to February, and the dry season is considered to be from May through to October. However, Layang-Laynag is only open to divers from March to August. Diving is possible year round at Sipadan. Beside one liveaboard which is allowed to take divers to Sipadan, all other diving is from land based resorts.
