Trail Ridge Road

A.k.a. US 34, in Rocky Mountain National Park, Colorado. The road follows this ridge at an elevation of over 10K ft, topping out at Iceberg Pass (11,827 ft/ 3605 m) before dropping down to cross the Continental Divide at Milner Pass. We're obviously above timberline here, and signs exhort people to stay off the tundra (see left inset). Obviously the weather could have been better, but at least the cloud deck was high enough to give some views. I did get into a snow squall, however, a little farther down the road, and a few days before the summer solstice (see right inset)! As it was, the road had just opened--unusually late, as it's usually open for the Memorial Day weekend. In any case, it's a spectacular route, recommended if you're in the area.
