Caribbean / Central America

Belize & the Barrier Reef

The world's second-largest barrier reef, three of only four true atolls in the Americas, and a sinkhole four hundred feet down that Jacques Cousteau called one of the finest dives on Earth — a week of shallow cayes and Maya ruins ashore, dry and calm from December to May.

Belize turns the barrier-reef idea inside out. Instead of one long wall offshore, a 190-mile reef — the world's second-largest — walls off a shallow lagoon studded with cayes (Belize's own word for its low sand-and-mangrove islands, pronounced “keys”) the length of the country, then rises again as three coral atolls further out in open water: Turneffe, Lighthouse Reef and Glover's, three of only four true atolls anywhere in the Americas. Placencia anchors the south, a sand peninsula with the country's one proper superyacht marina; Ambergris Caye anchors the north, four miles from a reserve thick with nurse sharks. Between the two lies the Great Blue Hole, a sinkhole so precisely circular it reads as manmade from the air.

“The reef that shelters this coast also limits it — the lagoon behind it runs to two or three metres in the north, and every cut through the wall is a daylight-only, eyeball call.”

Signature anchorages

Five stops across a 190-mile reef and the atolls beyond it — one true marina among them, and four anchorages worked by tender, local knowledge and a good agent.

  • PlacenciaYachts lie mostly off the village itself, across Placencia Lagoon from Mango Creek — good shelter behind the sixteen-mile peninsula and the reef beyond it, fair holding in lagoon mud. Placencia Marina, ten miles up the road, is the one berth in the country built for real length: to 275ft LOA (length overall) and 16ft alongside, 25 superyacht slips among its 293.
  • San Pedro & Ambergris CayeBelize's largest island, a narrow 25-mile spit with San Pedro its only town. The reef runs close inshore here, in places barely 300 metres off the beach, so the water off town is thin and coral-strewn — tender and dive-boat country, with deeper-draft yachts holding further out. Sand and turtle-grass bottom, good holding in settled trades.
  • The Great Blue Hole & Lighthouse ReefThe hole itself isn't an anchorage — 407ft deep and unmarked mid-atoll, reached by tender or dive boat some three hours out from San Pedro or Belize City. The atoll's real shelter is Half Moon Caye at its southeast corner: sand bottom, fair holding, under the lighthouse that has marked this reef since the 1820s.
  • Turneffe AtollBelize's largest atoll, thirty miles long and mangrove-fringed on its inner shore — good all-round shelter once inside the rim. A known anchorage north of Turneffe Flats holds a ten-foot draft on sand, but the pass and the set both want a local guide: most of the atoll's own boatmen work in four or five feet, not a yacht's chain. No fuel, no stores, on the atoll itself.
  • Glover's ReefThe southernmost and most remote of the three atolls, its lagoon holding more than 800 patch reefs behind an unbroken rim — sand bottom, well sheltered from the prevailing easterlies, exposed if the wind swings north. About 30 nautical miles out from Placencia; nothing ashore beyond a marine research station and a handful of small dive lodges on the rim cayes.

The reef, protected

Seven reserves carry the UNESCO listing between them. Belize banned all offshore oil exploration across its entire maritime zone in December 2017; the World Heritage Committee lifted the reef's decade on the In Danger list the following June.

Natural Monument

The Great Blue Hole

A collapsed karst sinkhole at the heart of Lighthouse Reef, 1,043ft across and 407ft deep, its stalactites dated back some 153,000 years to a time the sea itself stood lower. Jacques Cousteau charted it from Calypso in 1971 and called it one of the finest dive sites on Earth; the draw today is the rim and the drop-off, not the airless depths below.

Natural Monument · est. 1981

Half Moon Caye

Belize's first protected reserve, and Central America's first marine protected area, at Lighthouse Reef's southeast corner. Its red-footed booby colony — some 4,000 breeding birds, the only viable one in the western Caribbean — has been under protection since 1924; a lighthouse has marked the spot since the 1820s.

Marine Reserve · est. 1987

Hol Chan & Shark Ray Alley

Belize's first marine reserve — Hol Chan is Mayan for “little channel” — four miles south of San Pedro: reef, seagrass and mangrove across some eighteen square kilometres. Its Shark Ray Alley annexe, added in 1999, is a shallow, sand-bottomed gathering ground for nurse sharks and southern stingrays.

National Park · declared 1991

Laughing Bird Caye

A sliver of an island off Placencia, sitting on a faro — a shelf atoll, a rare and elongated ridge-reef formation — reckoned among the finest examples in the Caribbean. Named for a laughing-gull colony long since moved on; the reef around it remains one of the best short snorkels out of Placencia.

Marine Reserve

Gladden Spit & the Silk Cayes

Some twenty miles off Placencia, a reef promontory where spawning cubera snapper draw whale sharks in for a few days around the full moon, March to June — one of the more reliable whale shark aggregations anywhere in the Caribbean, inside a reserve built specifically to protect it.

Ashore, in the Maya lowlands

Inland into Cayo District — a hand-cranked river crossing, a headlamp-lit swim into the underworld, and a royal acropolis within walking distance of the region's market town.

Cayo District

Xunantunich

Reached only by a free, hand-cranked cable ferry across the Mopan River at San José Succotz, some eight miles west of San Ignacio. El Castillo, its main temple, stands 130ft — the second-tallest ancient structure in Belize — with a reproduced stucco frieze on its upper walls showing the Sun God flanked by the moon and Venus.

Tapir Mountain Nature Reserve

Actun Tunichil Muknal

A licensed guide, a forty-five-minute jungle hike fording a creek several times, then a short swim into the cave mouth. Inside, sock-only passages protect ceramics and calcite-covered Maya skeletal remains, among them the so-called Crystal Maiden; cameras and every electronic device have been banned since 2012, after one damaged the site.

Cayo District

Cahal Pech

A Maya royal acropolis on a hilltop at the edge of San Ignacio itself — seven plazas and thirty-odd structures, occupied from around 1000BC to roughly 800AD, close enough to town to fold into the same day as Xunantunich or the drive out to Actun Tunichil Muknal.

A week, sketched

Day 1

Placencia

Board at Placencia Marina, the only berth in the country built for real length overall, and settle in with a walk along the village sidewalk before a first night at anchor off the peninsula.

Day 2

Laughing Bird Caye & Gladden Spit

North along the reef to snorkel Laughing Bird Caye's rare faro formation, then out to Gladden Spit and the Silk Cayes — whale sharks for a few days around the full moon, March to June, reef life and spawning snapper year-round.

Day 3

Glover's Reef Atoll

Some 30 nautical miles offshore to the remote, southernmost atoll: a full day on the wall and among its 800-plus patch reefs, anchored well inside the lagoon behind an unbroken reef rim.

Day 4

Glover's Reef to Turneffe Atoll

A longer run up the outside of the barrier reef to Belize's largest atoll; a local guide comes aboard for the pass and the anchor, sheltered on sand north of Turneffe Flats.

Day 5

Turneffe to Lighthouse Reef & the Great Blue Hole

On to Lighthouse Reef for the rim of the Great Blue Hole, then ashore at Half Moon Caye Natural Monument for the red-footed booby colony and the lighthouse that has stood watch here since the 1820s.

Day 6

San Pedro & Ambergris Caye

North to Belize's largest island; an afternoon at Hol Chan Marine Reserve and Shark Ray Alley, four miles south of town, before an evening ashore in San Pedro.

Day 7

San Pedro, disembark

A final slow morning on the water before disembarking through San Pedro's own airstrip, or the short hop on to Belize City for the international connection.
