Old Baldy Trail is a 6.9 mile loop trail located near Lead, SD and is good for all skill levels. The trail is primarily used for hiking and is accessible from April until October.
This was an easy trail that I hiked yesterday 10/15/15. It was fairly well marked. Scenery was pleasant, but not exciting. However, when retuning to the trailhead at 3:30 pm, I met a mountain lion (big!) on the trail, about 50 ft. away. We stared at each other and then I raised my metal hiking poles above my head and banged them together until it left.
The trail is not very obvious the whole way but is marked with signs and has nice scenery. The climb and views from the top, at the end, are well worth the effort.
