The Matterhorn, Switzerland

Why It’s Amazing: Five hundred mountain climbers have died attempting to reach the rocky 14,692-foot summit of Switzerland’s majestic Matterhorn. The snow-covered, sawtoothed peak has a pyramidal summit that has become the textbook illustration of alpinism’s golden age and all its triumphs.
Secret Viewing Spot: Ascend Gornergrat by railway and exit at quiet Rotenboden station. Walk down the three-kilometer path to Lake Riffelsee, which on clear days offers majestic reflections of the mountain.
When to Go: The trail to Lake Riffelsee is open from July to October; the later you go, the less crowded it will be.
