Cruise ride on Bharamaputra: With less than half day in hand we decided to chill and watch the sunset sipping and eating at the deck of a boat. It was all worth it. There are a lot of cruise service which provide this service. You can either book it on phone (using Google search engine) or else go to the river side and book on the spot. I would suggest pre-booking. It's a 2hr ride where they take you across the river until sunset and back to banks.Other things to do in Guwahati: Kamakhya Temple, Botanical Garden, State museum, Kaziranga National park (if time permits then). There are lot of cafes around to try out. Like 11th avenue café, Brown bean café, the Steaming Mug, By the Way and many CCDs.
