Walk out onto the Glacier Skywalk which is 918 feet about ground for a breathtaking, heart racing experience. From the platform you will see waterfalls, wildlife, and the Columbia Glacier. Birds soar below you while you step out into a world of absolute beauty. I have to say, it was a hoot to watch my husband and kids take a step out onto the 1.5 inch thick glass, and promptly turn tail and step back on to the solid metal platform. They did eventually work up the nerve to walk all the way around…with a lot of choice words along the way. Oh, did I mention that the platform extends 115 feet from the cliff?
