Colorado Boat is a flume ride in Gardaland. It's worth seeing on a time-permitting basis.
Experience the excitement of the wilderness as you journey into a water-filled world. It's a nice mix of scenery and splashes and well worth going (even just to cool down), but it can feel a little bit short, especially if you have just waited in one of the queues that can sometimes be described as phenomenal! Try to do it late at night, beacause the lights in the distance are beautiful, especially when you are higher up.
