Level of Difficulty: 5-Intermediate, some really soft sandy trails, a couple rocky climbs.

Unfortunately I don't have any data on this ride as it was another victim of my computer crash.

 

I my memory serves me correctly, you can get to the unloading area by heading South on S 12th in Nampa, ID, which becomes SR-45 about 17 miles. Right after you cross the Snake River you will turn left to head south on SR-78 look for Upper Reynold's Creek Rd. Here is a MapQuest Link:
