McCarthy to Kennicott Trail
What to Expect
Safety Advisory
The Kennecott Mill buildings are genuinely hazardous — rusted metal, unstable floors, open shafts. Stay out of any structure not specifically opened for ranger-led tours, no matter how photogenic the doorway looks.
Bears are active in this valley throughout summer. Carry bear spray and make noise, especially on the quieter stretches between the two towns.
Trail Details
Pro Tips
The shuttle van runs between McCarthy and Kennecott regularly in summer and costs a few bucks — consider walking one way and riding back, especially if you plan to spend serious time exploring the mill buildings.
Kennecott offers ranger-led tours of the mill building interior, but slots fill up fast in July and August. Show up at the visitor center early or check the schedule the day before to snag a spot.
The trail is also open to vehicle traffic, so stay to the side. Most people walk it, but dust from passing shuttles can be a nuisance — a buff or bandana earns its keep on dry days.
