The boat journey connects three large backwaters of Kerala : Vembanad, Kayamkulam and Ashtamudi lakes by a canal system.
You can chose to return by the same boat, the next day or even catch the bus from the nearby KSRTC bus stand.
The itinerary from Alappuza : Alappuza –> Kannitta –> Pallathuruthy –> Kanjipadam –> Thottappally –> Thrikunnapuzha –> Ayiramthengu –> Amritapuri –> Chavara –> Kollam
Boasted as the longest backwater cruise in Kerala, the Kollam to Alappuzha (Quilon to Alleppey) boat ride is an 8 hours affair. The route practically connects the two towns.
Estuaries, lagoons, lakes and a network of interconnecting canals make the bulk of its backwater tourism. Kerala has plenty of backwater tourism hotspots, however some backwater destinations are immensely popular.
The pomp and fanfare apart, touring backwaters of Kerala in houseboat is an expensive affair. The rates are usually steep, running into a couple of thousand rupees per night, even during the off season.
