You can drive, cycle, bike, or hike to the top of Boreas Pass. Fun stop to learn about the old train route, along with spectacular views. Always full of muggles and at main stop, there is few old cabins and a train car to look around on. There are also 4 or 5 easyish geocaches near this point. At the top of Boreas Pass Road, you will find the trail head for Black Powder Pass Trail.
When you climb to the top, and it is a hard climb, with about 660 feet of steep elevation, you will get a view South Park and Georgia pass. Wildflowers galore on this trek! You are looking for an ammo can.
