Engineer Pass
Distance
~18 mi (Lake City → Animas Forks)
Time
3–4 hours
Difficulty
Difficult
The eastern crown of the Alpine Loop, crossing 12,800 ft between Lake City and the Animas River valley. The west side drops past Whitmore Falls and through Engineer Mountain's alpine bowls. The Ouray side (off the Mineral Creek spur) is markedly more difficult — narrow shelf road with serious exposure, often the technical highlight of the Loop. Connect Engineer + Cinnamon for the classic figure-eight Alpine Loop day.
