10 Best Things to Do in Belize

Looking for what to do in Belize? This small Central American nation packs an incredible amount of adventure into its borders — from Caribbean islands and coral reefs to ancient Maya cities, jungle rivers, wildlife reserves and one of the world’s most famous diving sites. Whether you’re staying on the mainland or hopping between the cayes, Belize offers a perfect mix of nature, culture, history and world-class marine life.

From exploring the Great Blue Hole and the Belize Barrier Reef to wandering ruins like Xunantunich, swimming in jungle caves and meeting wildlife in protected forests, Belize is a paradise for both adventure lovers and relaxed beach travellers. Here are the 10 best things to do in Belize for an unforgettable trip.

1. Dive or fly over the Great Blue Hole

The Great Blue Hole is Belize’s most iconic natural wonder — a perfectly circular sinkhole 300 metres (984 ft) across and over 120 metres (394 ft) deep. Whether you dive its vertical walls, snorkel the nearby reef or take a scenic flight above it, the Blue Hole is a bucket-list experience that showcases the striking beauty of Belize’s marine landscape.

Advanced divers can descend to see stalactites and deep caverns, while scenic flights from Caye Caulker or Belize City offer unforgettable aerial views of the deep navy circle surrounded by turquoise water. Even if you’re not a diver, the flight is considered one of the best sightseeing experiences in the Caribbean.

2. Snorkel the Belize Barrier Reef

Belize is home to the world’s second-largest barrier reef, a UNESCO World Heritage site filled with colourful coral gardens, nurse sharks, stingrays and tropical fish. Snorkelling sites like Hol Chan Marine Reserve, Shark Ray Alley, Mexico Rocks and South Water Caye Marine Reserve offer calm, clear waters and thriving marine life.

Joining a guided boat trip is the easiest way to explore multiple snorkelling spots in one day. Expect encounters with sea turtles, reef sharks, eagle rays and schools of snapper — perfect for beginners and experienced snorkelers alike.

3. Explore the ancient Maya city of Xunantunich

Xunantunich sits just outside San Ignacio, reached by a hand-cranked ferry across the Mopan River. This impressive hilltop archaeological site features plazas, temples and carved friezes dating back to AD 600–750. Its tallest structure, El Castillo, stands 40 metres (130 ft) high and offers sweeping views across the jungle and into neighbouring Guatemala.

Xunantunich is less crowded than Belize’s more famous Maya sites and offers one of the most atmospheric archaeological experiences in the region. Guides bring the city’s history and mythology to life as you move through ceremonial plazas and ancient stone paths.

4. Float through the jungle on a cave tubing adventure

Cave tubing is one of the most unique things to do in Belize. Travellers float on inner tubes through underground rivers that wind beneath limestone mountains, illuminated only by headlamps and soft reflections of the water. The Caves Branch system is the most popular spot, offering routes that pass through caverns filled with stalactites, cavernous ceilings and Maya ceremonial sites.

The mixture of jungle trekking, cool freshwater streams and mystical caverns makes cave tubing a highlight for families, couples and adventure seekers alike.

5. Visit vibrant Caye Caulker

Caye Caulker is Belize’s favourite laid-back island — a tiny, colourful Caribbean community where bicycles replace cars and the motto “Go Slow” is taken seriously. With sandy lanes, beach bars, reggae rhythms and easy access to the reef, it’s an ideal base for snorkelling trips, sailing excursions and kayaking.

The island’s famous Split — a channel dividing the island — offers clear turquoise water perfect for swimming and sunbathing. At sunset, head to Lazy Lizard or Iguana Reef Inn to watch pelicans dive as the sky turns pink and gold.

6. Discover wildlife in the Belize Zoo

The Belize Zoo is unlike typical zoos — all animals here are rescued, rehabilitated or born under human care, representing species native to Belize. Jaguars, tapirs, toucans, harpy eagles, ocelots and spider monkeys roam spacious enclosures surrounded by dense tropical vegetation.

The zoo is one of the best places in the country to see Belize’s elusive wildlife up close, especially for travellers who might not spot them deep in the jungle. It’s educational, ethical and perfect for families.

7. Wander the ancient city of Caracol

Caracol is Belize’s largest Maya site, hidden deep within the Chiquibul Forest Reserve. Once home to more than 100,000 people, this sprawling archaeological city includes temples, palaces, reservoirs and causeways stretching into the jungle. Its main temple, Caana (“Sky Palace”), is the tallest man-made structure in Belize.

Reaching Caracol involves a long but scenic journey through rainforest and pine forests, often paired with stops at Rio Frio Cave and Rio On Pools — two beautiful natural attractions perfect for swimming.

8. Cruise the New River to Lamanai

Lamanai is one of Belize’s most atmospheric Maya sites, reached by a scenic boat ride along the New River through mangroves, wetlands and jungle-filled riverbanks. Wildlife sightings often include crocodiles, howler monkeys and colourful birds.

The archaeological site itself features large plazas, temples covered in foliage and impressive masks carved into stone. The High Temple offers views across the jungle canopy, making the climb well worth the effort.

9. Relax in Placencia’s beaches and lagoon

Placencia is Belize’s premier beach destination, offering long sandy beaches, calm waters and a relaxed village atmosphere. It’s the perfect alternative to the cayes for travellers seeking a peaceful coastal escape with easy access to restaurants, bars and boutique hotels.

The nearby lagoon is home to manatees, while boat trips can take you to secluded cayes, snorkelling spots or the Silk Cayes Marine Reserve. Placencia also hosts one of Belize’s liveliest cultural events — the Placencia Lobsterfest.

10. Hike the jungle trails of Cockscomb Basin Wildlife Sanctuary

Known as the world’s first jaguar reserve, the Cockscomb Basin Wildlife Sanctuary protects over 150 square miles of pristine jungle, waterfalls, rivers and mountains. While jaguars are rarely seen, the sanctuary is filled with wildlife such as tapirs, armadillos, tropical birds and howler monkeys.

Marked trails lead to scenic viewpoints, riverbanks, waterfalls and natural swimming holes. It’s one of the best places in Belize for trekking and immersing yourself in untouched rainforest.
