Introduction to Manukan Island: Mnukan, the main island of the park, has the most complete tourist facilities, including hotels, tennis courts, water skiing centers, and wooden houses for accommodation. The west coast of the island is a rocky beach, not suitable for swimming and diving. The coast slope north of the ticket office on the east coast is relatively deep and there are large coral areas in the sea. You only need to swim a few meters to find a large coral area. The beach south of the ticket office is a very gentle slope. There is a fine sand area of ​​more than ten meters in the sea water. There are few people and it is very quiet. Diving here is the best option.
