About us Welcome to Hidden Depths Diving! We are a 5 Star PADI dive center based in Koh Lanta, Thailand. Welcome to Hidden Depths Diving! Our PADI 5 Star Instructor Development Center is based in Koh Lanta, Thailand, the beautiful island paradise nestled in the Andaman Sea. We have a beautiful speedboat that will take you to the dive sites quickly and comfortably, and with our late departures, you will have time to relax before your diving day begins. Our groups are small, with a maximum of four divers to a group, so you can be sure to receive the attention you deserve. We are eco-friendly and are the recipients of the only PADI Green Star award on Koh Lanta.
