Onam Festival: History, Traditions, & What to See in Kerala

Onam is Kerala’s most celebrated harvest festival, symbolising prosperity, unity, gratitude, and cultural pride. Celebrated over ten days during the Malayalam month of Chingam, the festival commemorates the annual homecoming of the legendary King Mahabali, whose reign is remembered as an era of peace, equality, and abundance.

From vibrant floral carpets (Pookalam) and grand vegetarian feasts (Onam Sadya) to thrilling snake boat races, folk dances, and temple festivities, Onam showcases the rich traditions of Kerala like no other festival. Whether you are planning to experience Onam in Kerala or simply want to learn about its fascinating history, this guide covers everything you need to know about the festival, including its significance, celebrations, traditions, travel tips, and the best places to witness the festivities.

History & Significance of Onam

The Onam festival honours King Mahabali, who, as per Hindu mythology, ruled with kindness and fairness. When Lord Vishnu, in the form of Vamana, asked for three paces of land, he covered the universe in two steps, and Mahabali offered his head for the third. Impressed by his humility, the Lord allowed him to visit his people once a year. Onam marks his homecoming, celebrated with feasts and festivities across the state.

The festival has been celebrated in Kerala for centuries, with the earliest mentions found as far back as the 3rd century in Tamil Literature. Here, it is described as a grand festival with feasts, games, and temple offerings. This makes Onam one of the oldest festivals still celebrated in India. Among its many highlights is the thrilling snake boat race, or Vallamkali, which began in the 13th century as contests between rival kingdoms on Kerala’s backwaters and continues today as a vibrant celebration of tradition, rhythm, energy, and teamwork.

What to See and Do During the Onam Festival

Onam is a festival best enjoyed by being part of its vibrant celebrations: joining the parades, watching the boat races, and tasting the traditional feast. While it is celebrated across Kerala, some of the best places to witness its charm are Thrissur, Kochi, Thiruvananthapuram, Alleppey, Athirappilly, and Trikkakkara. Here are the activities you can see or take part in during Onam 2026:

1. Tripunithura Athachamayam

This marks the first day of Onam, which is celebrated with joy and enthusiasm. The day begins with a grand parade that feels like a royal celebration. Decorated elephants, colourful floats, musicians, folk dancers, and drummers fill the streets. You’ll want to click pictures, but the scene is so mesmerising that you can’t look away! The best place to witness this grand celebration is Tripunithura town near Kochi, where the historic Athachamayam procession takes over the streets every year.

2. Vallamkali– The Snake Boat Race

Vallamkali is Kerala’s famous snake boat race, held on the Pampa River. During the race, the river bursts into life with the beat of drums and the cheers of the crowd. Long, narrow boats with over a hundred rowers glide through the water like snakes, moving in perfect rhythm. The Aranmula Uthrattathi Boat Race in Pathanamthitta and the Nehru Trophy Race on Alleppey’s Punnamada Lake are the most popular ones to watch. If you want to feel the thrill up close, Alleppey is the place to be.

3. Pulikali: The Grand Tiger Dance

Pulikali, meaning “the play of the tiger”, is one of Onam’s most colourful events. During the festival, hundreds of men paint themselves as tigers and dance to the loud beats of drums. It’s wild, energetic, and full of fun – a sight you’ll never forget. The best place to experience Pulikali is Thrissur, where thousands of people gather at Swaraj Round (Thekkinkadu Maidanam) to watch this unique street spectacle. 

4. Pookalam: The Floral Rangoli

Onam is also called the festival of flowers, and Pookalam is the heart of it. Every morning during the Onam festival, families create beautiful flower rangolis in their door fronts or temples as a ritual, which look like flower mats. Each day, new petals are added, making the designs bigger and brighter. Wherever you walk, the streets are alive with the colours and fragrance of these floral carpets. To see the most stunning and elaborate Pookalam designs, visit Thrissur or Kochi, especially at temples like Thrikkakara Temple, where grand competitions are held.

5. Kasavu Saree– Kerala’s Traditional Pride

During Onam, women of all ages, from little girls to grandmothers, wear the Kasavu saree, an off-white saree with a golden border. Simple yet royal, it is a proud symbol of Kerala’s culture. Seeing everyone dressed in it, you might feel like getting one yourself. And if you ask a local where to buy it, they’ll gladly guide you with a warm smile. For the most authentic ones, head to Kuthampully village in Thrissur district, famous for handwoven Kasavu sarees, or explore big textile stores in Kochi and Thiruvananthapuram.

6. Onam Sadya

One of the biggest highlights of Onam is the Onam Sadya, a grand vegetarian feast served on banana leaves. It can have up to 25 delicious dishes, each showing the flavours and traditions of Kerala. Picture yourself on a houseboat, enjoying this colourful meal as the backwaters drift by – a true taste of the festival. The Thrikkakara Temple near Kochi serves one of the most authentic Sadyas, while many restaurants in Thrissur, Kochi, and Trivandrum also curate special festive feasts. 

7. Traditional Folk Dances

You can also head out to see a Kathakali dance performance, where dancers in green face paint, headgear, and bold expressions tell stories through dance. You don’t need to know the language, as the eyes, the drums, and the moves say it all. For the best cultural experience, catch a show at the Kerala Kathakali Centre in Kochi or visit Kerala Kalamandalam in Thrissur
