How to Visit the Great Blue Hole in Belize: Tours, Flights and Tips
From the air, it looks unreal: a perfect circle of deep sapphire set into the turquoise shallows of the Caribbean. The Great Blue Hole is Belize's most famous natural wonder, and for many travelers it's the reason they book a Belize vacation in the first place.
The Blue Hole is a giant marine sinkhole about 300 meters (984 feet) across and roughly 125 meters (410 feet) deep. It formed during the last ice age, when sea levels were far lower and this was a limestone cave on dry land. As the ice melted, the ocean rose and the cave roof collapsed, leaving the near-perfect circle you see today. Jacques Cousteau brought it to the world's attention in the 1970s and ranked it among the best dive sites on the planet. Today it's part of the Belize Barrier Reef Reserve System, a UNESCO World Heritage Site.
The good news: you don't need to be a diver to experience it. Here's everything you need to know to plan your visit, from choosing between a boat tour and a scenic flight to building the rest of your Belize trip around it.
Where Is the Great Blue Hole?
The Blue Hole sits in the middle of Lighthouse Reef Atoll, about 70 km (43 miles) off the Belize coast and well beyond the main barrier reef. There's no hotel or dock at the hole itself, so every visit is a day trip by boat or a scenic flight overhead.
Two Ways to See It: By Boat or From the Air
By boat. Full-day dive and snorkel trips leave from Ambergris Caye (San Pedro), Belize City and a handful of resorts on the mainland coast. Expect an early start, usually around 6:00 a.m., and a boat ride of roughly two to two and a half hours each way across open water. You'll be back by late afternoon.
From the air. A scenic flight is the only way to see the Blue Hole's famous circular shape. Small planes and helicopters fly out from San Pedro and Belize City daily, and the round trip takes about an hour, with time circling above the hole and over the surrounding atoll. It's ideal for non-divers, families with young kids, anyone prone to seasickness, or travelers short on time.
Which should you choose? If you're a certified diver, the boat trip is a bucket-list dive. If you want the iconic photo and the full sense of scale, fly. Many of our guests do the flyover and spend their beach days snorkeling closer to shore.
What a Blue Hole Day Trip Looks Like
Most boat trips follow a similar route around Lighthouse Reef, with three stops:
The Great Blue Hole. Divers descend along the wall to about 40 meters (130 feet), where enormous stalactites hang from ancient cave ledges, a reminder that this was once dry land. Reef sharks often cruise the deep blue. Less experienced divers usually follow a shallower profile, and snorkelers explore the coral-lined rim.
Half Moon Caye. A short boat ride away, this protected island is a natural monument managed by the Belize Audubon Society. It's home to a colony of about 4,000 red-footed boobies, which you can watch from a viewing platform. Lunch is usually served here, with time to walk the beach.
The Aquarium at Long Caye. The final stop is a shallow, colorful reef often busy with turtles, eagle rays, moray eels and schools of tropical fish.
Good to know for divers: The deep Blue Hole dive is for experienced divers. Operators typically ask for advanced certification and a minimum number of logged dives (often 25 or more), and some require a checkout dive with them first. Bring your certification card and logbook.
When to Go
The dry season, from late November through mid-April, brings the calmest seas and clearest skies, which means a smoother boat ride and better visibility from the air. That said, trips run year-round. May through October is Belize's low season, with fewer crowds and better hotel rates, and many days are still beautifully clear. Flights and boat trips can be rescheduled if weather turns, so build a little flexibility into your itinerary.
What Does It Cost?
| Experience | Typical cost (USD) | Time |
|---|---|---|
| Blue Hole dive trip 3 dives + lunch |
About $300 to $410 per person, plus gear, tax and park fees | Full day, about 6 a.m. to 5 p.m. |
| Blue Hole snorkel trip | Similar to dive trips on many boats, per person | Full day |
| Scenic plane flight | About $200 to $300 per seat | About 1 hour |
| Helicopter flyover | Starting at $2,600 for 2 people | About 1 hour |
Marine reserve fees and Belize's 12.5% tax are often charged on top of the tour price, so ask what's included before you book.
What to Bring
Reef-safe sunscreen, a hat and polarized sunglasses
A rash guard or light long-sleeve layer for sun on the boat
Seasickness remedies, taken before you leave the dock
An underwater camera or phone case
A towel and dry change of clothes
Your dive certification card and logbook, if diving
Cash for tips for your crew
Our Insider Tips
Book early. Scenic flights have only a few seats per plane and fill up, especially in high season. Aim for at least a month ahead.
Plan it early in your trip. If weather cancels your day, you'll have time to reschedule.
Every seat is a window seat. Scenic flights use small planes and helicopters, and pilots usually circle the hole so both sides get a view.
Pace yourself. A boat day is long. Schedule a relaxed beach or spa day after.
Build Your Belize Trip Around the Blue Hole
The Blue Hole is one unforgettable day, but Belize rewards travelers who see both sides of the country: the reef and the rainforest. A classic itinerary pairs a few nights on Ambergris Caye, the easiest base for Blue Hole trips and flights, with time inland in Cayo for Maya ruins, cave tubing and jungle lodges, or in Placencia for quiet beaches and a laid-back village feel.
The challenge is that Belize is a country of small planes, boats and island hops, and stitching it all together on your own can take weeks of emails. That's where we come in.

Great Blue Hole FAQs
Can you swim or snorkel in the Great Blue Hole? Yes. Snorkelers can explore the shallow coral rim, though most of the hole is deep open water. The best snorkeling of the day is usually at Half Moon Caye and Long Caye.
Do I need to be certified to dive the Blue Hole? Yes. The signature dive reaches about 40 meters (130 feet), so operators require advanced certification and solid experience. Newer divers can often join on a shallower profile.
How long does it take to get to the Blue Hole? About two to two and a half hours each way by boat, or about 20 minutes each way by plane or helicopter.
Is the Blue Hole worth it if I don't dive? Absolutely. A scenic flight shows the hole's full shape, which you can't see from a boat, and it takes about an hour.
What's the best place to stay for a Blue Hole trip? Ambergris Caye is the most convenient base, with daily boat departures and scenic flights from San Pedro.
When is the best time to visit the Blue Hole? Late November to mid-April for the calmest seas and clearest skies, but May to October offers lower rates and fewer crowds.
