This 10-mile trail in Black Diamond Mines Regional Preserve in Antioch will take us over rolling hills, open fields, and into an 1800s coal mine. It should take us between 5.5 and 6.5 hours to complete. Expect a moderately strenuous hike with lots of exposure. An early start means an early(ish) finish, so you’ll still have some of your Sunday for other fun.
There is no potable water along the trail, be sure to bring enough with you. Here’s how to calculate how much you’ll need.
Qualifies as a 10-mile hike for Hiking merit badge. Earns a Pathfinder rocker patch.
