A well-planned dive trip is safer, more enjoyable, and more likely to deliver the marine life encounters you came for. Planning should start at least three months before departure for international trips, and at least two weeks in advance for local diving.

Before You Book

• Check seasonal conditions — Water temperature, visibility, and wildlife seasons vary significantly. Refer to the seasonal wildlife chapter for timing guidance.
• Verify your certification level — Some dive sites and liveaboards require Advanced Open Water or specialties (Deep Diver, Drift Diver, Nitrox). Check requirements before booking.
• Obtain DAN or equivalent dive accident insurance — Standard travel insurance does not cover hyperbaric chamber treatment. See the DAN chapter of the Safety Guide for details.

Gear Preparation

• Service your regulator annually — do not skip this before a dive trip.
• Check BCD inflation/deflation and inspect hoses for cracks or corrosion.
• Verify your dive computer has fresh batteries or is fully charged.
• Pack backup mask, fin straps, o-rings, and a multi-tool for equipment issues on the road.

Documentation

• Certification card (physical or digital — screenshot the digital version).
• Dive log showing recent dive history (many operators want to see your last 10–20 dives).
• Medical statement if you have any relevant health conditions.
• Dive insurance policy number and emergency contact.

Medical Considerations

Diving with certain medical conditions requires a physician's clearance. Conditions that commonly affect dive fitness include asthma, cardiovascular disease, epilepsy, and pregnancy. Use the RSTC (Recreational Scuba Training Council) medical form as a starting point, and consult a dive medicine physician if you have any concerns.
