The first breaths underwater come after a day in a warm hotel pool, the chlorine giving way to salt and sun on day three. In Bangkok you’ll study theory and rehearse skills in controlled pool sessions before boarding a dive boat for two open-water days, where the city’s bustle is replaced by the steady hiss of regulators and the slow choreography of reef life.

Bring a fitted mask
Masks provided are fine, but a personal, well-fitting mask prevents fogging and discomfort during repeated skills sessions.
Hydrate and avoid alcohol
Diving dehydrates; drink water before and between days and skip alcohol 24 hours prior to diving.
Prep for motion
Boat rides can be choppy—take motion-sickness medication before boarding if you’re prone to seasickness.
Plan around visibility
Book open-water days between November and April for the best visibility and calmer seas in the Gulf of Thailand.
Personal dive mask & snorkel
A well-fitted mask reduces fogging and improves comfort during skills practice and surface intervals.
Rashguard or thin wetsuit top
Protects against sun and jellyfish while keeping you warm during long surface intervals.
summer
Dive computer (or rental computer)
