At 3,100m, the air is thin (about 65% oxygen of sea level). Every step requires intention. But here's the magic: find the spot 50 meters past the main viewing platform where you're alone. Just you, the Matterhorn, and 29 four-thousanders visible in all directions (Monte Rosa, Lyskamm, Castor, Pollux). Exit the summit building, walk along the marked ridge trail heading toward the Gornergrat observatory. Bring a small bottle of Valais wine from the valley. Pour a splash on the snow as an offering to the mountain gods. Drink the rest slowly. This is what people climb for. Best time: sunrise (first train 8am) for empty ridge and golden light, or sunset for alpenglow.
🔄 BACKUP: If weather is bad (fog, high winds), stay inside the restaurant and watch for breaks in clouds - the Matterhorn appears and disappears like magic.
