During these ten days, there are numerous entertaining activities such as Vallam Kali (boat racing), Pulikali (tiger dances), Pookkalam (flower Rangoli), Onathappan (worship), and Pookalam.
The floral rangoli created during the event is known as Onam Pookalam and is often round in shape. Onam Pookalam is also known as ‘Athapoo’ since it starts on Attam, the first day of Onam, and ends on Thiruonam, the last day.
