Whenever anyone thinks of backwaters, Kerala comes to their mind and rightly so because Kerala is home to country's gorgeous backwaters.
There are two places in Kerala for an awesome backwater experience : Kochi and Alleppey.
I started my journey from Kochi. From the Kochi airport, I took a bus to reach Fort Kochi. Fort Kochi is the best area to stay if you're visiting Kochi. Here you will find many tour operators offering various backwater tours.
I participated in the tour that was arranged by the hostel where I was staying. The tour costed me 850 INR and it included lunch as well as transportation to and fro from the hostel.
The tour started at 8 am. We reached the site where the tour starts at around 8:40 am. We were around 16 people so two boats were arranged. As soon as the tour started I was blown away by the beauty and calmness of the backwaters.
