Despite its name, Langkawi Coral is one of the few dive schools in Penang. The company has two branches: one in Langkawi and the other approximately five kilometres (3.1 miles) north of George Town. Langkawi Coral prides itself on promoting green and sustainable tourism, offering both PADI and SSI courses. Both cover scuba essentials, including the theory and plenty of practice, as well as safety and equipment familiarisation. PADI courses last four days, costing RM1900 ($476 USD), while an SSI Open Water Certification Course takes three days at RM1800 ($451 USD).
