Why an island guide
Ask a group of divers about their favorite trip and most will name an island. Bonaire, Palau, Cozumel, the Maldives, Raja Ampat, the Galápagos: islands are where the deep water, healthy reefs and big animals come together. They are also where trip planning gets tricky, with monsoons and hurricane seasons, small planes, liveaboards and marine park rules that differ from place to place.
Isla Scuba brings that information together in one place. Instead of ranking islands, we group them by region and describe what each is known for, so you can match an island to the diving you enjoy. The name comes from the Spanish word for island, isla, a nod to the many Spanish-speaking islands and coasts where divers travel.
What you will find here
- Region guides for the Caribbean, the Pacific, Southeast Asia, the Indian Ocean and the Atlantic, each with island-by-island notes, seasons and common questions.
- A guide to the best islands for beginner divers, with what to look for and how a first course works.
- An island dive trip planning guide covering seasons, liveaboards, insurance, packing and flying after diving.
How we write our guides
Our pages stick to information you can check: geography, marine parks and when they were protected, well-known dive sites, typical seasons and widely published safety guidance, such as the Divers Alert Network recommendations on flying after diving. We describe seasons as rough guides, because weather patterns shift from year to year and local operators always know best.
We do not list prices, opening times or individual businesses, because those change often and an out-of-date listing is worse than none. When you are ready to book, check current details with the dive center, liveaboard or park authority directly.
Nothing on this site replaces proper dive training. Dive within the limits of your certification and experience, follow your guide's briefing and the rules of each marine park, and carry dive insurance.

Corrections and suggestions
Islands change. Reefs recover or decline, parks change their rules, and new wrecks are sunk as artificial reefs. If you spot something that is out of date or wrong, we want to hear about it. Our contact details are in the Privacy Policy and the Terms of Use.
