Once we park we take a truck to the top of Bogus Basin Ski Resort and we take The East Side trail down from the resort to the Hard Guy Parking Area.
While this one is mostly downhill there are plenty of uphill challenges as you go, and we did see a bear along the way. There is also one big climb at the end to top it off as well then a nice mostly downhill run to the parking lot on a paved road.
From Boise take Harrison Blvd to Bogus Basin Rd. Take that up about 5 miles to the Hard Guy Parking area.
