Both sister, did not find initially the trail on the way up, it was nice to use it on the way back. Did West first, and then walked onto the East one.
The trail is part of a Hardrock race and it is definitively worth searching for it.
Both Twins plus neighboring 12ers PT 12601 and PT 12579 from an unnamed trail across from the abandoned mine. We think the trail is part of the Hardrock 100 trail run route. Early season and it still had some snow patches that made the trail hard to follow in the trees adding some annoying bushwhacking when we lost it.
Started the hike from South Mineral Campground Parking at 6:45. Soon began to rain. I did not give up. Rain continued for more than 2 hours. Summited at 10:50 when rain had stopped. Clouds made dramatic scenes. Back to car at 2:30.
