The tram isn't cheap, but it's worth it for anyone who otherwise might not make it to high alpine tundra during an Alaska trip. (In winter, ride on your lift ticket; in summer, ride free with a meal at the Seven Glaciers Restaurant at the top.) The tram takes 7 minutes in summer to get to the 2,300-foot level, where it stops at a station containing both the Seven Glaciers and an attractive but pricey cafeteria, the Glacier Express. Whether or not you eat here, the tram presents an opportunity for everyone, no matter how young, old, or infirm, to experience the pure light, limitless views, and crystalline quiet of an Alaskan mountaintop. Take the opportunity to walk around and enjoy it. Dress very warmly.
