There are two options for visitors to go to Koh Larn. One is to go there by ferry, while speedboat is the other option, and both of them can be taken at Bali Hai, near Pattaya Walking Street, South Pattaya. In the ferry case, visitors can take a ferry from 7.00 to 18.30, and a ferry will, in general, depart every hour. It is very cheap, only 30 Baht. There are two ports on Koh Larn, Naban Port, and Ta wan Beach (one is not far from the other, anyway). On the other choice, speedboats for impatient visitors, visitors can transfer to Koh Larn in 15-20 minutes, but it will cost you more, approximately 1,200 - 1,500 Baht / boat. (It will be more valuable for a group of visitors)
