After an exhilarating boat ride across the Kelani River you can begin your jungle trekking in the Kitulgala Rainforest at Kitulgala City. Hikers can cool off by taking a dip in the water before making the return trip, thanks to the hiking trail’s passage through small streams, boulders and hidden waterfalls. Whitewater rafting excursions in Kitulgala are a must-do for adventure seekers. Beginning your two-hour five-kilometer rafting trip in the Kelani River with a paddle requires only wet gear. Take a swim after rafting to unwind then head back to shore. The site where ‘The Bridge on the River Kwai’ was filmed in 1957 is open to the public. Even though Thailand is home to the original Kwai River bridge, tourists can still see the remnants of the wooden bridge that director David Lean constructed for the explosive train scene. The world of film history will be introduced to you during an enthralling stroll to the site.
