12 Things to Know About Grand Cayman Before You Arrive

When you think of Grand Cayman, the first images that come to mind are probably soft white beaches, turquoise waters, and gentle stingrays gliding through the shallows. And yes — you’ll find all that here. But Cayman is more than just picture-perfect postcards. Grand Cayman is a safe, friendly, and surprisingly easy island to explore.

Here are 12 things to know about Grand Cayman before you arrive — straight from locals who love to share their island.

1. The West Side Is the Active Side

Grand Cayman might only be 22 miles long, but where you stay makes a big difference in your vacation experience.

• Seven Mile Beach (West Side): If you love an action-packed trip, this is your spot. Hotels, condos, restaurants, and beach bars are all within walking distance. Every day can be filled with activities, and every evening with something delicious to eat.
• North Side and Cayman Kai: Looking for peace and quiet? Rent a condo or villa here. You’ll definitely need a car, but the trade-off is your own slice of paradise away from the crowds.
• West Bay: A happy middle ground. You’ll enjoy a little more calm but still be close to the lively west side.

2. Driving Is on the Left

Since Cayman is a British Overseas Territory, the steering wheel is on the right, and cars drive on the left. It may feel unusual at first, but you’ll adjust quickly — especially since all rental cars carry special plates and decals to remind you.

Roundabouts are common, so take your time. And if you get turned around (it happens!), don’t worry. Caymanians are famously friendly and will happily point you in the right direction.

3. Stingray City Is World-Famous

Imagine standing in waist-deep water surrounded by southern stingrays gliding past you like friendly ocean puppies. That’s Stingray City — Grand Cayman’s most famous attraction.

These stingrays are wild but used to gentle human interaction. They’ll swim right up to you, brushing against your legs or even letting you hold them if you’re comfortable. It’s safe, magical, and unforgettable.

Pro tip: A private Crazy Crab charter means you’ll have more time with fewer crowds, so you can soak up the experience without being rushed.

4. Large Supermarkets Close on Sundays

This one often surprises first-time visitors. Because of Cayman’s strong religious traditions, the island’s big supermarkets stay closed on Sundays. Smaller neighborhood shops and gas stations stay open, but hours are reduced — and liquor sales are restricted.

Restaurants and tours still operate as usual, so you won’t go hungry. Just don’t leave your grocery shopping for Sunday morning. If you arrive on a Saturday, stock up before the stores close for the weekend.

5. Bioluminescent Bay Will Take Your Breath Away

Grand Cayman is one of the rare places in the world where you can see glowing plankton at night. In the amazing Bio Bay, when the water is disturbed — by your hand, a paddle, or the wake of a boat — millions of microscopic organisms light up with a blue-green, shimmering bioluminescence.

This natural wonder is best seen snorkeling in the shallow, warm water of the Bio Bay. Crazy Crab’s private night charters let you slip quietly into the glowing water and experience it without the big crowds. It’s one of those bucket-list experiences you’ll be talking about long after you leave.

6. Plan Around Cruise Ship Days

Grand Cayman welcomes over one million cruise visitors every year. On busy days, as many as six ships anchor offshore and tender passengers to George Town. That can make popular attractions like the Crystal Caves, Queen Elizabeth II Botanical Park, or downtown shopping feel crowded.

Luckily, the Port Authority posts the cruise ship schedule online. A little planning goes a long way — if you want a more relaxed experience, visit the big attractions on light cruise ship days, or head out on the water to escape the crowds altogether.

7. The Water Is as Clear as Glass

Divers and snorkelers rave about Cayman for good reason. Visibility in the water often reaches 100 feet or more, meaning you can see vibrant coral reefs, darting fish, and even the sandy seabed in remarkable detail.

Favorite snorkel spots include Coral Gardens, Rum Point Reef (keep an eye out for eagle rays and moray eels), and shallow coves perfect for beginners. If you’ve ever wanted to try snorkeling as a family, Grand Cayman’s calm, bathtub-warm waters make it the perfect place.

8. Cayman Is the Culinary Capital of the Caribbean

Food is part of the Cayman experience. From roadside jerk stands and conch fritters at beach bars to fine dining restaurants helmed by world-class chefs, the island has earned its title as the culinary capital of the Caribbean.

Highlights include fresh snapper and mahi-mahi, spiny lobster in season, and local specialties like Cayman-style beef or cassava cake. For a handy guide, check out our blog: Crazy Crab’s Favorite Restaurants.

9. Warm, Welcoming — and Safe

Visitors often say one of the things they love most about Cayman is the people. Caymanians are known for their warmth, hospitality, and easygoing charm. It’s not unusual for a stranger to stop and help if you look lost, or strike up a friendly conversation at the beach bar.

Grand Cayman is also one of the safest destinations in the Caribbean. Families with young kids, couples, and solo travelers alike can relax and feel comfortable exploring day or night.

10. You Need a Passport for the Cayman Islands

All visitors need a valid passport and proof of onward or return travel to enter the Cayman Islands.

• U.S., Canadian, U.K., and most European citizens don’t need a visa for short stays.
• Passport validity should cover your stay (though many airlines recommend six months to be safe).
• Children also need their own passports, and if only one parent is traveling, a notarized consent letter may be required.

Cayman Islands travel requirements are refreshingly simple — just pack your passport, and you’ll be ready to slip into island time.

11. There’s More To Do in Cayman Than Beaches

Yes, Grand Cayman is famous for Seven Mile Beach — but venture inland and you’ll find plenty of surprises.

• Mastic Trail: A lush hike through preserved dry forest filled with native plants and birds.
• Caves and Blowholes: Natural limestone formations carved by centuries of waves.
• Cayman Turtle Centre: A mix of conservation, education, and hands-on fun for families.

If you love nature and culture as much as the ocean, set aside a day to explore beyond the beach.

12. The Best Experiences in Cayman Are by Boat

No matter how many lists you read, one thing stands above them all: the best way to experience Grand Cayman is on the water.

A private Crazy Crab charter lets you do it all — visit Stingray City, snorkel pristine reefs, swim in bioluminescent waters, or enjoy your deserved vacation while relaxing on deck with a cold drink in hand.

Because at the end of the day, Cayman isn’t just about what you see. It’s about how you feel when you’re out on the water, surrounded by beauty, laughter, and that warm Caymanian spirit.
