📌Location
Half Moon Caye is a small crescent-shaped caye located at the southeastern corner of the Lighthouse Reef atoll, the easternmost of Belize's three atolls, about 80 kilometers off the coast from Belize City. It's been a protected Natural Monument since 1982 and is part of the Belize Barrier Reef Reserve System, a UNESCO World Heritage Site. Famous for its colony of red-footed boobies, its historic lighthouse and one of the most beautiful beaches in the Caribbean, it's managed by the Belize Audubon Society
📌Gateway town
There's no town or permanent services on the caye: only a Belize Audubon Society ranger station. It's reached exclusively by sea, on diving and snorkeling excursions by speedboat from San Pedro (Ambergris Caye), Caye Caulker or Belize City (2 to 3 hours of navigation), or on dive cruises (liveaboards). Philip Goldson International Airport (BZE), near Belize City, is the gateway to the country and to the departure bases
📌Best time to go
The dry season, from late November to mid-April, is the best for visiting Half Moon Caye: the sea is usually calm and with good visibility, key conditions for the long crossing from the coast. The colony of red-footed boobies can be observed for much of the year, with the most active nesting season between the end of one year and the start of the next. The rainy and hurricane season (June to November) brings a rougher sea and less reliable excursions
📌Suggested days
Most people visit Half Moon Caye on a full-day excursion from San Pedro or Caye Caulker, which usually combines the Great Blue Hole (on the same atoll) with snorkeling or diving stops at the caye and its reef. To spend more time, divers choose multi-day dive cruises that tour the atolls. The Belize Audubon Society allows, with authorization, camping on the caye for longer nature stays, with very basic services
📌Currency
Belize dollar (BZD), pegged at 2 BZD = 1 USD. The park fees are charged in Belizean or US dollars. It's best to bring cash, since on the caye there are no ATMs or card machines

Half Moon Caye is one of the most beautiful and serene corners of the whole Caribbean. This small crescent-shaped caye —hence its name— sits at the southeastern corner of the Lighthouse Reef atoll, about 80 kilometers off the coast of Belize, surrounded by turquoise waters and a reef in excellent condition. Its very white sand beach, its coconut palms leaning over the sea and its stillness make it a perfect postcard of a tropical desert island.
But Half Moon Caye is much more than a dreamlike beach: it's a Natural Monument protected since 1982, one of Belize's first protected areas, and a wildlife sanctuary. Its greatest treasure is the colony of red-footed boobies, one of the few large colonies of this spectacular seabird in the Western Hemisphere, which nests in the caye's trees along with frigatebirds. An observation platform lets you contemplate the bustle of the colony from above. The caye is also a sea-turtle nesting area and keeps the remains of the historic lighthouse (1820) that gave its name to the whole atoll, which collapsed in 2010 after Tropical Storm Matthew and was replaced by a modern beacon.
This guide covers the practical side of visiting Half Moon Caye with an honest eye: it's a remote destination, with no town or services, reached after a long crossing by boat or dive cruise. It's almost always combined with the visit to the Great Blue Hole, which is on the same atoll. For those who make the effort to get there, the reward is enormous: snorkeling and diving over pristine corals, a unique bird colony and one of the most photogenic beaches in the Caribbean, all in a protected, almost pristine setting.
📖 History of Half Moon Caye
Half Moon Caye owes its name to its characteristic crescent shape and, in turn, gave its name to the atoll that surrounds it: on this caye a lighthouse was built in the 19th century to warn navigators of the dangerous reef, and hence 'Lighthouse Reef'. Geologically, the caye is an accumulation of sand and coral debris on the southeastern edge of the atoll, a coral formation that grew over millennia on limestone foundations as the sea level rose after the last glaciation. The waters that surround it were navigated by the Maya, who traded along the coast, and later by buccaneers and colonial ships that feared its shoals. The great conservation milestone came in 1982, when Half Moon Caye was declared a Natural Monument —one of the country's first protected areas— to safeguard its colony of red-footed boobies, managed ever since by the Belize Audubon Society. In 1996, the whole Belize reef system, including Half Moon Caye and the nearby Great Blue Hole, was inscribed as a UNESCO World Heritage Site. The full story is on our history page.

Red-footed booby colony and observation platform
One of the few large colonies of this seabird in the Western Hemisphere, with a lookout to see it up close.
The greatest wildlife treasure of Half Moon Caye is its colony of red-footed boobies, a seabird with bright-red feet and a bluish bill that nests in the caye's trees. It's one of the few large colonies of this species in the entire Western Hemisphere, which makes the caye a site of extremely high value for birdwatching and conservation. Thousands of frigatebirds coexist with them, often seen gliding over the caye.
The Belize Audubon Society built an elevated bird observation platform, reached by a short trail through the coastal forest. From the top, the visitor is literally at the height of the treetops where the boobies nest, which lets you see the adults, the nests and the chicks up close, in a nature spectacle hard to match. The noise, the movement and the smells of the colony are quite a sensory experience.
It's important to respect the rangers' instructions, keep quiet and not stray from the trails so as not to disturb the birds or damage the caye's fragile ecosystem.
How to get there: within the visit to Half Moon Caye, on the excursions from San Pedro, Caye Caulker or Belize City. Best time: the colony can be observed for much of the year; nesting is more active around the end/start of the year. Tips: bring binoculars if you have them, a camera with a good zoom, a hat and sunscreen; always follow the guide or the reserve's signs.
ℹ️ Distance: Short trail from the caye's landing beach · Best time: Much of the year; nesting more active around the end/start of the year · Admission: Belize Audubon Society fee BZ$ 20 / US$ 10 per person (source: Belize Audubon Society, official, verified July 2026); usually included in the excursion · Duration: 30 to 60 minutes

Half Moon Caye beach
Very white sand, coconut palms and turquoise waters on one of the most beautiful and quiet beaches in the Caribbean.
The beach of Half Moon Caye is, quite simply, one of the most beautiful in Belize and the Caribbean. Its sand is very white and fine, the water is a transparent turquoise and the coconut palms lean over the shore creating the perfect image of a tropical desert island. Being a Natural Monument with no tourist development, it keeps a pristine look and a tranquility that's now hard to find at busier destinations.
During the day excursions, the caye is usually the stop to rest, have lunch (many excursions bring lunch), swim and snorkel right from the shore, as well as walk the trail to the bird colony and the lighthouse. It's an ideal place to disconnect, walk on the sand and enjoy the silence, broken only by the sound of the sea and the birds.
The beach is also a sea-turtle nesting area, so in certain areas and seasons there are restrictions to protect the nests. As in the whole reserve, you have to respect the rules: don't leave trash, don't collect shells or coral and don't disturb the wildlife.
How to get there: on the diving/snorkeling excursions and cruises that visit the atoll. Best time: dry season, with a calm sea. Tips: bring sunscreen (preferably reef-safe), a hat, water and little luggage; there are no shops or services, so bring what you need for the day.
ℹ️ Distance: On the caye itself, next to the landing point · Best time: Dry season (Nov-Apr) · Admission: Included in the Natural Monument fee (BZ$ 20 / US$ 10 per person, verified July 2026) · Duration: Variable (part of the excursion day)

The historic lighthouse site (and its story)
The spot where the lighthouse that gave the Lighthouse Reef atoll its name stood, today with its remains and a modern beacon.
The Half Moon Caye lighthouse is a key piece of the atoll's history: it was precisely this tower that gave the whole formation its name, 'Lighthouse Reef'. The signal station was established in 1820, the tower was rebuilt in 1848 and reinforced with a steel structure in 1931, to warn navigators of the danger of the coral shoals. For more than a century it was one of the few signs of human presence in this remote corner of the Caribbean.
You should know before you go: the historic lighthouse is no longer standing. It was decommissioned in 1997 and, weakened by coastal erosion, finished collapsing in September 2010 after the passage of Tropical Storm Matthew. Today, at the eastern end of the caye, you can see its remains and a modern metal tower (erected in 1998) with a solar beacon that still performs the function of marking the reef. The walk to this point, through the coastal forest and next to the bird observation platform, is still part of the classic tour of the caye, with lovely views of the reef.
It's a perfect complement to understanding why this point was historically so feared by sailors and why its strategic and natural value led to its protection.
How to get there: along the caye's trail, within the visit to Half Moon Caye. Best time: any visit day. Tips: comfortable footwear for the trail and care with the sun; ask the guide about the history of the lighthouse and photos of the original tower.
ℹ️ Distance: Eastern end of the caye, at the end of the trail, next to the bird platform · Best time: Any visit day (dry season preferable) · Admission: Included in the visit to the Natural Monument (BZ$ 20 / US$ 10 per person, verified July 2026). The original lighthouse collapsed in 2010; you can see its remains and the modern beacon · Duration: Part of the caye tour

Diving and snorkeling on the Half Moon Caye reef
Coral walls, shallow gardens and abundant marine life, including the famous Half Moon Caye Wall.
The reef that surrounds Half Moon Caye is one of the great attractions of the place and the reason it's included in almost every atoll diving excursion. The most famous site is Half Moon Caye Wall, a dive wall (drop-off) where the reef drops vertically toward the depths, carpeted with corals, sponges and sea fans. It's a spectacular dive for its biodiversity and its excellent visibility.
In these waters coexist sea turtles, rays, moray eels, groupers, snappers, parrotfish and schools of colorful reef fish, plus reef sharks. Because of the distance from the coast and the protection of the reserve, the coral is in very good condition and the marine life is abundant.
Those who don't dive can equally enjoy snorkeling: the shallow waters over the corals and next to the beach offer a spectacle of color without needing to descend deep. Day excursions commonly combine the Blue Hole (deep diving), snorkeling at Half Moon Caye and a stop at another point of the reef.
How to get there: on the diving/snorkeling excursions and cruises from San Pedro, Caye Caulker or Belize City. Best time: dry season, with better visibility. Tips: respect the coral (don't touch it or stand on it), use reef-safe sunscreen and, if you have your own snorkeling gear, bring it for greater comfort.
ℹ️ Distance: Reef surrounding the caye (Half Moon Caye Wall, drop-off) · Best time: Dry season (Nov-Apr), better visibility · Admission: Included in diving excursions (US$ 285–395/day) and snorkeling (US$ 175–269/day), range according to caye operators, verified July 2026 · Duration: Depending on the excursion

Littoral forest trail
A unique coastal forest that covers half the caye, home to iguanas, hermit crabs and migratory birds.
Beyond the beach and the bird colony, Half Moon Caye holds a little-known but valuable ecosystem: a littoral forest, one of the best-conserved coastal forests in Belize. It covers much of the caye and is toured along an interpretive trail that connects the landing point with the observation platform and the lighthouse.
The forest changes notably between the two halves of the caye: in the eastern half, the poor soils give low, twisted trees like the ziricote; in the western half, wetter and richer thanks to the birds' guano, coconut palms and denser vegetation grow. Along the trail you come across iguanas, hermit crabs, lizards and numerous birds, since the caye is an important stopover for migratory species that cross the Caribbean.
Walking through this miniature forest, with the murmur of the sea in the background and the seabirds flying over, is an intimate way to get to know the caye beyond its beach postcard. The Belize Audubon Society keeps the trail marked and asks that you not stray from it to protect the nests and vegetation.
How to get there: on foot from the landing beach. Best time: early in the morning, with more bird activity. Tips: repellent, closed footwear and respect for the wildlife and nests.
ℹ️ Distance: Interpretive trail through the caye · Best time: Early morning, more wildlife activity · Admission: Included in the Natural Monument fee (BZ$ 20 / US$ 10 per person, verified July 2026) · Duration: 30 to 45 minutes

Nature camping on the caye
Spending the night on a protected desert island, with very basic services and permission from the Belize Audubon Society.
For adventure travelers, Half Moon Caye offers an uncommon experience in the Caribbean: the possibility of camping on a desert island within a Natural Monument. The Belize Audubon Society manages a small campground next to the ranger station, where you can stay overnight with prior permission, pitching your own tent or using one of the basic facilities.
The services are minimal: simple restrooms, a rustic shared kitchen and little more; you have to bring water, food and everything you need, since there are no shops on the caye. In exchange, you get something priceless: waking up on a pristine beach, watching the sun rise over the reef, hearing the bird colony at dawn and having the caye almost to yourself when the day excursions leave.
Some adventure operators also offer organized multi-day 'basecamps' that combine tent-cabin lodging with kayaking, snorkeling and diving, in all-inclusive packages. It's a deep way to connect with this remote corner of the Caribbean.
How to get there: by sea, coordinating the transfer and the permit with the Belize Audubon Society or an operator. Best time: dry season (Dec-May). Tips: arrange the permit in advance (info@belizeaudubon.org); bring enough water and supplies.
ℹ️ Distance: Next to the caye's ranger station · Best time: Dry season (Dec-May) · Admission: Own camping US$ 50 per person/night, park + kitchen + entry (source: Belize Audubon Society, verified July 2026); organized 8-night basecamps from US$ 2,200 per person (source: Island Expeditions) · Duration: 1 or several nights
