These 1½-hour boat trips around the lake are the main way to tour the sanctuary without taking a guided walk. You might see deer, boar, otters and birdlife but it's generally more of a cruise than a wildlife-spotting experience. Boats are operated by the KTDC – you need to buy a ticket from the main building above the boat jetty before boarding the boat.
In high season get to the ticket office 1½ hours before each trip to buy tickets. The first and last departures offer the best prospects for wildlife spotting, and October to March is generally the best time to see animals.
