Adventure-seekers will love this active day out that includes whitewater rafting and ziplining with some sightseeing. After a handy early-morning pickup, head to the beautiful Suwan Khuha Temple for a look around. Then, get active on the water, splashing and bouncing your way down about 3 miles (5 kilometers) of river. Walk to a waterfall, refuel with a tasty Thai lunch, then zoom through the forest on a zipline.
