I wrote before about how I got certified in Cozumel back in 2015 and how it took about thirty seconds underwater to know I had a new problem for my wallet. This is the part two — the actual dives, the island itself, and what I'd tell you if you're thinking about going.
The First Dives
Certification week started easy. Shallow reef dives just off the coast to get comfortable — buoyancy, basic skills, getting used to breathing underwater without thinking about it. Cozumel is a forgiving place to learn. The water is warm, visibility is usually excellent, and the reefs start close to shore so you're not burning half your air just getting there.
Once the basics were locked in, we worked up to a deeper dive — down to about 80 feet. That's where it starts to feel like real diving instead of a pool exercise. Color starts dropping out at that depth without a light, the reef structure gets more dramatic, and you start paying real attention to your gauges instead of glancing at them.
We did four dives total in that first stretch. Honest review — the fish count on a couple of them was lower than I expected, because the current was running slightly strong that day. Current pushes a lot of the smaller reef fish into cover, and it makes you work a little harder just to hold position and look around instead of drift past everything. Still a great set of dives. Just not the aquarium-still conditions you see in the brochure photos.
A Little Cozumel History
Cozumel isn't just a dive destination that happened to have good reefs — the island has a real history behind it. The Maya considered it sacred, dedicated to Ixchel, the goddess of the moon, fertility, and childbirth. Mayan women were expected to make a pilgrimage to the island at least once in their life to honor her, traveling by canoe across the channel from the mainland. There are still Mayan ruins on the island today, the most well-known being San Gervasio, believed to have been a temple site connected to that pilgrimage tradition.
That history is part of what makes Cozumel feel different from a lot of other resort islands — it wasn't built for tourism, tourism grew on top of something that was already significant for over a thousand years before anyone was filling a scuba tank there.
Punta Sur and the Basics
Punta Sur Eco Beach Park, on the southern tip of the island, is worth a stop if you're not spending the whole trip underwater. It's got a lighthouse you can climb, a crocodile reserve, more Mayan ruins, and a beach that's a nice contrast to the dive boats. Good half-day trip if you want a break from the water or you're traveling with people who aren't diving.
A few basics for anyone planning a first trip:
- • Getting there — Cozumel has its own international airport (CZM), or you can fly into Cancún and take the ferry from Playa del Carmen, which runs regularly and takes under an hour.
- • The city — San Miguel de Cozumel is the only real town on the island, where the cruise ships dock and most of the restaurants, shops, and dive operations are based. Very walkable.
- • Safety — Cozumel is one of the safer, more tourist-established parts of Mexico. Common sense travel precautions apply, same as anywhere, but it's not a place that should make you nervous.
- • Reef-safe sunscreen — the reef system around the island is part of the Mesoamerican Barrier Reef, the second largest in the world, and a lot of operators will ask you to use reef-safe sunscreen specifically to protect it. Worth packing ahead of time.
Where to Stay, Depending on Your Trip
This depends a lot on who you're traveling with and what you actually want out of the trip.
Traveling with kids or family — look at the all-inclusive resorts further south on the island. They handle everything — food, drinks, activities, beachfront cabanas — so you're not managing logistics every day. Good call if you want the trip to be relaxing rather than a project.
Solo, with friends, or want more city access — staying closer to San Miguel puts you near the restaurants, the dive shops, the nightlife, and the walkability. Good option if you want flexibility instead of a resort schedule. Just — don't drink too much. I say that half-joking, but only half.
A Word on the Beer Cruises
You'll see them advertised everywhere — the beer cruises, the tequila cruises, the booze-boat day trips. They can be a fun time, and plenty of people have a great afternoon on one. But know what you're getting into: open bar, boat, sun, and strangers is a combination that adds up faster than people expect, especially if you're not used to drinking in heat.
Have fun. Just know your limits, watch out for your group, and keep your head about you. The best trips are the ones you actually remember.
One more practical thing — if you're taking a taxi anywhere on the island, pre-pay through an app like Uber if it's available, or agree on the fare before you get in. Saves an argument and a bad note to end the night on.
Worth It
Between the diving, the history, and the island itself, Cozumel earns the reputation. Go in with a plan that fits how you actually like to travel, respect your limits, and you'll have a great trip.
Part 3 covers what happens after you surface — safety stops, decompression basics, and why you shouldn't book your flight home too soon.
