Kettuvalloms (huge traditional boats in Kerala) were earlier used to carry tonnes of rice, spices and other such materials. In the past few years, these have been reformed as ‘Luxurious Houseboats’ to provide the tourists with the true joy of spending their vacations on enchanting backwaters. Houseboats provide the wonderful opportunity to discover the enchanting backwaters and lively villages of Kerala.
