Like many others on here, we only booked this activity because our heli-hike was cancelled due to bad weather. It was a perfect alternative...in fact, do it even if your heli-hike isn't cancelled! They provide quality protective clothing, the quads are sturdy and speedy and the guides are great. You get to have a briefing and practice on the quads before zooming across varied terrain towards the glacier. It was pouring with rain when we went out, so you couldn't really see the glacier, but in my opinion the wet weather made it more fun. Really good value for money for those with a sense of adventure!
