Nestled in misty hills, Kandy is the island’s cultural capital and home to the revered Temple of the Tooth Relic (Sri Dalada Maligawa), one of Buddhism’s holiest shrines. Pilgrims and travellers alike come to witness the rituals performed daily in honor of the sacred relic of the Buddha.
Beyond its spiritual allure, Kandy enchants visitors with its scenic lakefront setting, colonial architecture, and lively cultural performances. If you’re visiting in July or August, don’t miss the Esala Perahera, a grand procession of elephants, drummers, and dancers, a dazzling display of tradition and devotion.
Dating back over 2,000 years, Anuradhapura was Sri Lanka’s first capital and remains one of the greatest monastic cities of the ancient world. Its sprawling ruins tell stories of kings, monks, and spiritual devotion.
Here, you’ll find towering stupas (dagobas) like Ruwanwelisaya, sacred ponds, intricately carved stone pillars, and the revered Sri Maha Bodhi Tree, believed to be a sapling from the tree under which the Buddha attained enlightenment. Anuradhapura is not just a historical site but also a living pilgrimage destination where the island’s Buddhist heritage thrives.
Following the fall of Anuradhapura, Polonnaruwa became Sri Lanka’s royal capital in the 11th century, flourishing as a hub of art, architecture, and irrigation. Today, its well-preserved ruins give a glimpse into the island’s medieval grandeur.
Highlights include the Gal Vihara, a stunning collection of colossal Buddha statues carved from a single granite rock, the royal palace ruins, and ancient tanks (reservoirs) that showcase the advanced engineering skills of the era. Exploring Polonnaruwa feels like stepping back into a sophisticated kingdom of the past.
Often called the Eighth Wonder of the World, Sigiriya is one of Sri Lanka’s most iconic landmarks. Rising 200 meters above the plains, this ancient rock fortress was once a royal citadel built by King Kashyapa in the 5th century. Its summit reveals the remains of a palace complex with sweeping views of surrounding forests and villages.
On your way up, admire the world-famous Sigiriya frescoes, painted maidens that have survived for centuries, and walk through the Mirror Wall, once polished so brightly that the king could see his reflection. The combination of history, artistry, and breathtaking views makes Sigiriya an unforgettable experience.
On Sri Lanka’s southern coast, Galle Fort stands as a living testament to the island’s colonial past. Built first by the Portuguese, fortified by the Dutch, and later occupied by the British, this seaside fortress blends European influence with South Asian culture.
Today, its cobblestone streets are lined with boutique hotels, art galleries, cafés, and museums, making it one of the most vibrant heritage towns in Asia. Stroll along the fort ramparts at sunset for sweeping ocean views, or simply lose yourself in the fort’s old-world charm.
Also known as the Golden Temple of Dambulla, this cave complex is the largest and best-preserved in Sri Lanka. Carved into a massive rock outcrop, it houses more than 150 statues of the Buddha and intricate murals that date back over 2,000 years.
Each of the five main caves offers a unique experience, from towering Buddha figures to ceilings covered in exquisite religious paintings. Dambulla remains a living temple where devotees continue to worship, adding a vibrant spiritual atmosphere to its timeless art.
Sri Lanka’s last remaining primary rainforest, Sinharaja, is a biodiversity hotspot teeming with endemic species of flora and fauna. Recognized by UNESCO as a natural World Heritage Site, it’s a paradise for eco-travelers and birdwatchers.
Walking through its dense canopy, you might spot the Sri Lanka blue magpie, purple-faced langurs, or giant squirrels. The forest’s lush greenery, waterfalls, and trails create a magical escape into nature’s embrace - a stark contrast to the island’s historic sites.
The Central Highlands of Sri Lanka, including Horton Plains, Knuckles Conservation Forest, and Peak Wilderness, showcase the island’s highland ecosystems. Rolling tea plantations, cloud forests, and cascading waterfalls make this UNESCO site a natural wonderland.
Highlights include World’s End in Horton Plains, where dramatic cliffs drop over 800 meters, and Adam’s Peak (Sri Pada), a sacred mountain where pilgrims climb thousands of steps to witness sunrise at its summit. The Central Highlands are where adventure, spirituality, and nature converge.
