Paddling along on a calm waterbody in a tiny kayak might seem like a simple activity, but, unless you have arms and shoulder strength like Popeye's, it could knock the wind out of you. The good thing is that, with views like these all around, you'll hardly notice your quivering arms. Strap on your life jacket and pick from the tandem or solo kayaks (tip: if you pick the tandem kayak, you can share the paddling with someone and, by 'share', we mean let somebody else do all the work). Pay close attention when your instructor gives you the low-down on kayaking rules, especially in case you topple over. But don't fret, there aren't too many rules and you'll pick up kayaking skills quickly, slicing through the waters of the green rivers with a happy grin plastered on your face. In a tandem kayak, all you have to do is paddle, while the instructor takes care of other stuff like navigation and handling the rudder, if needed.
