Just a word of advise, do not take any snorkeling package offer at Lumut Jetty. While these people will say that it is much expensive at the island, it is actually cheaper. They will charge you RM 120/boat in actual fact, you can get the same arrangement for only RM80/boat. These are scammers and will charge you the different (between RM40 to RM50) for their 'consultation' fee. Please be aware of this arrangement and spread it out to warn others.
