Onam is one of the biggest and most popular festivals in Kerala, and it sees the participation of families, friends, and tourists from all corners of the country and outside. During this Onam holiday, the beautiful Alleppey backwaters become one of the most suitable places to visit; hence, houseboats are in high demand, leading to record booking rates. When you visit Alleppey for Onam celebrations, book your Onam houseboat early.
