Top 10 Diving Destinations for 2024

If you're planning a dive trip this year, the window for booking is closing fast. The best destinations fill up 2–3 months ahead, and 2024 has already seen record booking volumes across Southeast Asia and the Caribbean. This guide covers ten destinations where you can actually get a spot, what you'll see underwater, what the courses cost, and which ones are worth the hype versus which ones are overrated. We've weighted these by visibility windows, marine life variety, school quality, and value — not by Instagram popularity or marketing spend. Some are familiar names; others will surprise you. All ten are diveable right now, with realistic availability on WeGoDive.

TL;DR

• Indonesia (Raja Ampat + Komodo) offer the highest marine biodiversity on Earth — expect 4–6 species of sharks per dive, but book 4+ months ahead and budget $2,500–$4,500 for a week-long liveaboard
• Thailand's Similan Islands deliver consistent 20–30m visibility and healthy coral for $1,200–$1,800 per week, with PADI courses running $350–$500 for Open Water
• Egypt's Red Sea is cheapest entry point globally at $200–$300 for certification courses, with year-round warm water and minimal current variability
• Colombia's Caribbean coast remains underbooked relative to quality — Taganga and Cartagena have certified schools at $250–$400 for OW, and you'll see fewer crowds than Thailand or Mexico

Best for Marine Biodiversity: Indonesia (Raja Ampat)

Raja Ampat isn't overhyped — it's just expensive and remote, which keeps it from feeling overrun. The numbers back it: 75% of Indo-Pacific coral species live here. On a single dive, you'll reasonably see wobbegong sharks, giant groupers, schooling barracuda, and at least two ray species. Visibility runs 15–25m in the dry season (November–March), dropping to 10–15m June–September.

Most divers access Raja Ampat via liveaboard. Budget $3,000–$4,500 for a 7-day trip including flights from Bali. Land-based operations exist in Sorong but are less common; liveaboards dominate because the best reefs are 1–3 hours by boat. If you're AOW-certified, you can dive directly. If not, expect to pay $100–$150 extra for AOW certification onboard.

The catch: Book 4–5 months ahead during peak season. Last-minute availability exists June–September (cooler water, lower viz, fewer crowds), which actually works if you're comfortable in 26°C water.

Best for Value and Accessibility: Thailand (Similan Islands)

Similan remains the working diver's destination — good visibility, healthy reefs, and schools that actually have their act together. Expect 20–30m average viz, 28–30°C water, and coral gardens plus occasional leopard sharks and eagle rays. The Similans deliver consistent mid-range dives, not the "once in a lifetime" drama of Raja Ampat, but exactly what you want for a week.

A full week (6–8 dives) costs $1,200–$1,800 including accommodation and diving. PADI Open Water certification runs $350–$450 with reputable operators. Similan season is November–May; June–October water gets murky and conditions are choppy.

Where people mess up: Booking the absolute cheapest operator ($800/week) often means boat crowding (15+ divers per dive), rushed briefings, and instructors focused on volume. Mid-range schools ($1,400–$1,600) give you 6–8 divers per guide and actual attention to buoyancy.

Best for Warm Water and Year-Round Diving: Egypt (Red Sea)

The Red Sea is the global entry point for budget-conscious divers. PADI Open Water costs $200–$300 with certified schools in Sharm El-Sheikh, Dahab, or Hurghada. Water temperature averages 24–28°C year-round — warm enough that you need only a 3mm wetsuit even in winter. Visibility holds 15–25m most of the year; currents are predictable and managed (not feared).

A week of diving plus accommodation runs $600–$1,000 including dives. That's $100–$150 per dive. Certification courses take 3–4 days and cost less than a night out in most Western cities.

The Red Sea works especially well for PADI AOW students (reefs are ideal for new skills like navigation), rescue course candidates, and anyone building their logbook. It's crowded — there are 40+ dive operators in Sharm alone — which means competition keeps prices low and standards consistent.

One real limitation: Coral bleaching from warming water has hit sections of the Red Sea harder than other regions. Ask your operator which sites are looking best before committing.

Best for Fewer Crowds: Colombia (Caribbean Coast)

Taganga and Cartagena get 10% of the diver traffic of Koh Tao or Cozumel, despite having comparable marine life and cleaner water. Visibility averages 15–20m. You'll see spotted eagle rays, reef sharks, and healthy coral gardens — nothing rare, but abundant and reliable.

PADI Open Water certification costs $250–$400. A week of diving with accommodation runs $800–$1,200. The differential between Colombia and Thailand is about $400–$600 for the same week, but you're trading crowd density for that savings.

Taganga (small town, dive-focused) has 5–6 established schools; Cartagena (tourist destination, UNESCO World Heritage site) has more operators but wider quality variance. Most divers do 3–4 days diving in Taganga, then explore the old city separately.

What to watch: The Caribbean coast has two strong seasons — dry (December–March) and secondary dry (August–September). June–November you'll hit rain and reduced visibility. Book November–February for best conditions.

Red Flags and What to Avoid

Don't book diving in these scenarios:

• Solo travel companies that bundle "scuba packages" without naming the operator. You can't review a shop you don't know. Always book directly with the school or through transparent marketplaces where you see the actual operator name.
• Any course that promises PADI certification in 2 days. PADI Open Water requires 4 confined-water sessions minimum, plus 3 open-water dives. Real courses take 3–5 days depending on prior experience.
• Operators advertising "no prior diving needed" for liveaboard dives. Liveaboards assume you're AOW-certified minimum. If you're OW-only, you're limited to 18m depth, which removes most liveaboard sites.
• Visibly overcrowded boat operations (15+ divers per guide, no predive briefing). This correlates directly with safety incidents and boredom.
• USD pricing that's significantly lower than peer operators. One shop charging $200/dive when others charge $280 usually means cutting corners on maintenance, guide pay, or both.

Bottom Line: Where to Book Your 2024 Dive Trip

If you're certified and want maximum marine life: Indonesia (Raja Ampat or Komodo) — book now for late 2024. If you want reliable conditions, good value, and less travel friction: Thailand (Similan Islands) November–April. If budget is your primary driver: Egypt (Red Sea) — best bang-for-buck globally. If you want authentic diving without the Instagram crowd: Colombia — underrated and genuinely less busy.

All four destinations have certified schools on WeGoDive. Filter by location, read recent diver reviews (not the operator's own testimonials), and check the specific season windows above — booking a dive trip to Thailand in June feels cheaper until you're sitting on a boat in 2-meter visibility.
