A favorite tourist activity is the canopy zip lining. Even if you are nervous and deathly afraid of heights and any amusement park rides, this is still so much fun, more exhilerating.  They have a couple locations on the island, usually in or near Dennery.  The guides are helpful and you should feel safe and secure.  And there's so many palm trees around that you don't feel like you are so high off the ground. This is definitely recommended and you don't need to be fit or athletic. They fit you with a harness and helmet and thick gloves and once they attach you to the line, you glide along for about 5-10 seconds to the next platform and then you do it again !  So much fun !!
