Mega Zipline is the coolest zipline ride in Finland. And, fittingly, Finland’s coolest zipline starts from the top of the X-Tower, Europes’s tallest adventure tower! The starting point is a whopping 32,5 metres above the ground level. The ride itself goes for an incredible 330 metres. If you dare to open your eyes, as you zoom through the air high above the trees, you will see the beautiful Kalajoki sand dunes and the blue shimmering of the sea.
