The backwaters of Kerala, running parallel to the Arabian Sea, are one of the most popular tourist destinations in India. The scenic backwater stretch of Thiruvallam is a tourist's paradise, where Rivers Killi and Karamana meet, before becoming one with the sea. The backwaters are ideal for kayaking, canoe rides and cruises in kettuvallams or large traditional trading vessels used for transportation of rice and spices to nearby towns.

While the scenic beauty around the waterways is mesmerising, these spacious and well-decorated houseboats add to the charm of the experience. Traditionally, a kettuvallam would be around 60 ft long and 15 ft wide at the beam. Some of the new houseboats have a length of more than 80 ft! Constructed from locally sourced natural materials such as jackfruit tree wood, palm wood, coconut fibre, bamboo poles, ropes, bamboo mats etc., these boats offer guilt-free tripping. They are constructed by tying together (rather than nailing) wooden planks with coconut coir. The planks are coated with resin extracted from cashew nut shells. Bamboo poles and palm leaves are used for constructing the roof. Some of these boats also have solar panels for generating electricity. If carefully maintained, these boats can last for decades.

Regular trips are organised by the Boat Club to the nearby islands of Edayar and Pozhikara, as well as to a few coir manufacturing units. The Akkulam Boat Club offers facilities for boating on Akkulam Lake. A short distance from Thiruvallam lies Veli Lagoon, another great place for water sports. The lagoon comprises a waterfront park and a floating bridge as well.
