Try Dive, Open Water and beginner packages – small groups with SDI, TDI and PADI instructors at Chang Diving Center.
Looking for beginner scuba diving in Koh Chang or a trusted place to learn to dive in Thailand? This page is the hub: every entry-level course we run at Chang Diving Center — from a one-day Try Dive to full Open Water Diver certification, plus OWD & AOWD packages and longer professional pathways. Small groups, warm water, and SDI, TDI and PADI instructors — then pick a course card below.
Never dived? Start with a Try Dive or go straight into Open Water if you’re ready to study theory and skills. Already tried elsewhere? Continue with Open Water or a combo package. Families, couples and solo travelers all train in the same beginner-friendly format — see course FAQ for age, medical and scheduling questions.
Try Dive — no license, two boat dives, full supervision. Scuba Diver (on the Open Water page) — first certification with a pro to 12 m. Open Water Diver — dive independently with a buddy to 18 m worldwide (typically 3 days on Koh Chang). Want both steps? Our Open & Advanced package stacks certifications in one trip.
Training happens on real local dive sites — colorful reefs, gentle profiles, and famous spots like the HTMS Chang for later fun dives. Read our Marine Life Guide for what you might see. After certification, many divers add specialty courses or continue toward pro training.
Not ready for a full course? Join a day trip or — if already certified — fun dives. For step-by-step planning, see our How-to Guides and contact us to match dates and courses.
