Onam in Kochi: where the festival opens
The soul of Kerala, celebrated by everyone
Kochi is where Onam officially begins. On Atham, the first of the ten days, the Athachamayam procession winds through Tripunithura on the city's eastern edge, and the Thrikkakara Vamanamoorthy temple, the shrine of the Onam story, starts its own ten-day festival. Onam: 3–15 September 2027, with Thiruvonam, the main day, on 12 September 2027. From a base in Ernakulam the tiger dancers of Thrissur and the boat races of the Pamba are day trips.
Kochi sits inside the Onam map rather than beside it: the festival's official opening procession happens in Tripunithura on the city's own edge, and the tiger dance, the votive boat race and the big regatta are all within about three hours by road.

Athachamayam: the opening parade in Tripunithura
Athachamayam is held every year on the Atham asterism of the Malayalam month of Chingam, in Tripunithura, once the seat of the Maharajas of Cochin. Kerala Tourism describes it as a cultural pageant that recalls a victory of the Raja of Kochi: before independence the Maharaja rode out with his entourage to meet his subjects. The parade was halted in 1949, when Travancore and Cochin merged, and revived in 1961, when Onam became Kerala's people's festival.
Today the procession starts and ends at Attam Nagar, near the high school ground, without a king but with the full royal order: caparisoned elephants, floats, musical ensembles and almost every folk art form of Kerala. A three-day ritual comes first, opened by a royal town crier who arrives on an elephant and beats a drum. After the parade there is a sadya (festive meal) and an awards ceremony for local people.
Roads in Tripunithura close from early morning, so come the day before. The same town has the Hill Palace Museum, the Cochin royal family's residence built in 1865.
Thrikkakara: the temple of the Onam story
The legend of Onam centres on King Mahabali, a generous asura (demon) king. In the story told in the Bhagavata Purana, Vishnu came to him as Vamana, a dwarf Brahmin, and asked for three paces of land; Vamana then grew to cosmic size and covered the worlds in two strides, and Mahabali offered his head for the third. In Kerala, Onam is the time when Mahabali is believed to return to his people. Tradition holds that Thrikkakara, about 10 km north-east of Ernakulam, was Mahabali's seat, and the name is read as 'place of the holy foot'.
The Thrikkakara Vamanamoorthy Temple is one of the 108 Divya Desams, the holy places of Vishnu, and Onam is its main festival. It opens with a flag hoisting on Atham. Each day the image of Vamana is dressed in sandalwood paste as a different avatar of Vishnu. On the ninth day the Pakalpooram procession takes the deity round the temple on an elephant with about eight caparisoned elephants and panchavadyam; the festival ends with the Aarattu, the ritual bath of the image, and the lowering of the flag. The temple's Onam sadya draws more than twenty thousand people of many faiths. Dress modestly and leave shoes outside.

Practical notes
Onam is Kerala's biggest homecoming, and the pressure lands on transport first.
- Weather — Onam falls at the end of the monsoon: in August Kochi averages about 18 rainy days and 458 mm of rain, in September about 16 days and 359 mm, with days around 30–31°C. Carry an umbrella to every outdoor event.
- Where to base yourself — Ernakulam for the trains, the metro to Tripunithura and the ferries; Fort Kochi and Mattancherry are slower and prettier but add a ferry to every early start. See where to stay in Kochi and getting around.
- Sadya — The Thiruvonam meal of rice and more than two dozen dishes on a banana leaf is eaten at home; restaurants serve it too, and seatings at well-known kitchens are booked ahead. If you are invited to a home, accept.
- Crowds — Athachamayam and the Pulikali day draw very large crowds. Follow police diversions and instructions, keep belongings close, and know the emergency number, 112.
