CozumelQuintana Roo, Mexico
Caribbean · Drift
Current, cattle boats, and how to pick an operator
Dive styleBoat drift, 2-tank mornings
Typical depth40–90 ft, walls go deeper
Cert levelOW is fine; AOW helps on Santa Rosa / Palancar
Budget$$ — two-tank ~ $90–130
Cozumel is the easiest “real” diving in the hemisphere. The whole island is a marine park, the current does the swimming for you, and the walls on the southwest side (Palancar, Colombia, Santa Rosa) are as good as anything in the Caribbean. The price is that everyone knows it.
- Pick the small boat. The big resort boats run 16–20 divers and dive to the slowest person. Six-pack operators cost a little more and you get better sites, longer bottom times, and a divemaster who actually watches your group. Ask how many divers per guide before you book.
- Drift means drift. You don't fight the current; you fly it. Get neutral early, stay slightly above the guide, and keep your buddy in front of you where you can see them. On a ripping day at Santa Rosa you will cover half a mile without kicking.
- Afternoon wind. Mornings are calm; by 1–2 pm the chop builds. Book morning two-tanks, spend afternoons eating.
- Norte season (Dec–Feb). Cold fronts can close the port for a day or two. Build a spare day into a winter trip.
- Logistics. Flying into Cancún and taking the ferry from Playa del Carmen is cheaper but adds two to three hours each way with gear. Flying direct to CZM is worth it on a short trip.
- Stay south of town if your op picks up at the hotel pier — it cuts 30 minutes of boat commute each morning.
Highlights: Palancar Bricks, Columbia Deep, a night dive at Paradise Reef. Skip: the cruise-ship-day crowds at the shallow sites.
BonaireDutch Caribbean
Shore · Self-guided
The truck-and-tank routine
Dive styleShore diving, unlimited tanks
Typical depth20–80 ft, reef slope
Cert levelOW + comfort navigating without a guide
Budget$$ — tanks ~ $30–40/day unlimited, plus truck
Bonaire is the place where you learn what your dive habits really are, because nobody is managing you. You get a pickup truck, a drive-thru tank fill station, and a map of sixty-plus sites marked with yellow rocks. Then you dive whenever you feel like it.
- The rhythm: early dive before breakfast, two mid-morning, long lunch and nap through the heat, one late afternoon, and a night dive every other day. Four to five dives a day is normal here; your body will tell you when it's not.
- Ironshore is sharp. Wear boots, not full-foot fins. The entries at sites like 1000 Steps (it's about 70) and Karpata are worth it, but plan the exit before you get in.
- Leave nothing in the truck. Nothing. Windows down, doors unlocked, empty. It's the local convention and it works.
- Marine park tag. Buy the STINAPA nature fee online before you dive; you'll do a checkout/orientation dive with your shop the first morning.
- Nitrox is nearly a must. With four dives a day at moderate depths, EAN32 keeps you out of deco and you feel better at dinner.
- Hidden gem: the Salt Pier (when no ship is docked) at dusk, and the east coast on a calm day with a guide.
Highlights: all of it. Bring: a save-a-dive kit, because the nearest shop may be 30 minutes back down the road.
RoatánBay Islands, Honduras
Caribbean · Boat
Walls five minutes from the dock
Dive styleBoat, single-tank, short rides
Typical depth40–100 ft walls
Cert levelOW fine; AOW for the deeper wall sites
Budget$ — packages are some of the best value in the Caribbean
Roatán is the budget-friendly answer to “I want walls and I want a lot of dives.” The Mesoamerican reef wraps the island, and West End / West Bay operators run three single-tank boat dives a day with rides that are often under ten minutes.
- West End vs. West Bay. West End is the dive town: cheaper, walkable, more shops, better food. West Bay is the resort beach. Stay West End, take the water taxi to the beach.
- Three-dive days. The single-tank rhythm (back to the dock between dives) is easy on the body and easy to skip a dive without guilt.
- Sharks. The shark dive at Cara a Cara is a baited dive; decide for yourself how you feel about that. Regular sightings on the walls are common without it.
- Sandflies are real. Long sleeves at dusk, and don't skip the repellent because you're “used to it.”
- Getting there usually means a connection through Houston, Miami, or Atlanta. Saturday is changeover day; midweek flights are cheaper.
Highlights: Mary's Place, the El Aguila wreck, any wall on the north side after a calm night.
Florida KeysKey Largo → Key West
USA · Boat
No passport, big wrecks, weekend-able
Dive styleBoat, 2-tank, reef & wreck
Typical depth25–60 ft reefs; 60–130 ft wrecks
Cert levelOW for reefs; AOW / deep for Spiegel Grove & Vandenberg
Budget$$ — two-tank ~ $90–120; lodging is the cost
The Keys are where US divers should go before spending international money. The reefs are shallow and forgiving, the wrecks are enormous, and if the weather blows out you're still in Florida with a rental car.
- Key Largo for the Spiegel Grove, Duane, and the Christ of the Abyss cliché (do it anyway). Key West for the Vandenberg. Marathon for Sombrero Reef and fewer people.
- Wreck depths are honest. The Spiegel's deck is 60–90 ft and the current can be stiff on the mooring line. Bring a reel and know how to use it; treat these as deep dives, not tourist dives.
- Summer is the season. Winter cold fronts bring wind and 3–5 ft seas; summer brings flat water, warm temps, and afternoon storms that mostly hit after you're back at the dock.
- Lionfish are everywhere; several ops run culling dives if that's your thing.
- Drive it. Fly to MIA or FLL, rent a car, and the Overseas Highway is part of the trip.
Highlights: Spiegel Grove on a slack tide, Molasses Reef at dawn. Skip: the Saturday snorkel-boat combo trips.
MontereyCalifornia
USA · Cold water
Cold, kelp, and worth every layer
Dive styleShore (Breakwater, Point Lobos) and boat
Typical depth20–70 ft
Cert levelOW + cold-water experience or a local guide
Budget$ — parking and tanks; gear rental adds up
If your diving has all been in 80°F water, Monterey will humble you and then hook you. Sea lions buzz you at the Breakwater, the kelp at Point Lobos looks like a cathedral, and nudibranchs are everywhere once your eyes adjust.
- Thermal plan first. A 7mm with hood and gloves gets you two dives if you're tough; a drysuit gets you a season. If you're going to dive cold water more than twice a year, take the drysuit course.
- Re-do your weight check. Thick neoprene plus a steel tank plus salt water is a completely different weighting problem. Budget a first dive for it.
- Point Lobos needs a reservation (state reserve, limited daily dive teams). Book weeks ahead for weekends.
- Surge and surf entries. Check the swell forecast, not just the weather. The Breakwater is protected; most other shore sites are not.
- Fall is the window. September–November usually brings the calmest seas and the best vis.
Highlights: Point Lobos Whalers Cove on a flat day, a Metridium Fields boat dive. Bring: a thermos and a big changing mat.
