MacDonald Pass to Priest Pass Via Continental Divide Trail is a 10.8 mile moderately trafficked loop trail located near Helena, Montana that features a great forest setting. The trail is rated as moderate and primarily used for hiking and mountain biking.
I'm going to hit this trail again, the day I did it, there was so much deadfall it was a challenge. That's just an observation. Trees fall. It's all good. And it's close enough to Helena to be a good day-hike that doesn't necessarily consume the whole day.
