A reverse image search (via TinEye) reveals the original photo to be published on Unsplash. The author notes the location is Boulder, Colorado, USA.
Boulder is a city that sits on the foothills of the east side of the Rocky Mountains. This means the mountains are to the west of the city. The photo features a hairpin turn which is a common type of corner on mountain roads. Looking at a map of Boulder, there seems to be four roads of significance that go between the city and the mountains:
- Linden Drive
- Sunshine Canyon Drive
- Boulder Canyon Drive (State Highway 119)
- Flagstaff Road
From the map, only Flagstaff Road has hairpin turns. The turn features only a short straight until the next turn when going up the road (in elevation) and the city appears to the right when looking down both entry/exit at the apex. Only one corner has these features, which places the location to be on Flagstaff Road with the following decimal coordinates: 40.001048, -105.294817 (Google Maps, Google Street View).
