Hidden Campground Professional Review and Guide
"A peaceful, beautiful, almost poetic setting on the shoulders of the upper Imnaha River, this is one of our favorite little campgrounds in the state. It’s even easier to appreciate Hidden Campground after the drive down from Joseph, which is gorgeous but requires a certain degree of alertness, even though it is entirely paved. The road starts oﬀ as a gentle grade up on Little Sheep Creek Road, with wide views of the Wallowa Valley as it falls away behind you; as you turn onto FS 39 (also known as the Wallowa Mountain Loop Road), it becomes a twisting, narrow, roller-coaster ride that will either be loads of fun or a bit nerve-racking, depending on your inclinations.
To get here, you’ll pass through an area that burned in 1988 and work your way toward the ultimate drop down to the Imnaha River Road (FS 3960), approximately 30 miles from the start of Wallowa Mountain Loop Road (FS 39). Be sure you have a good USGS map of the area, as the road signs can be confusing. (Hint: Start by following signs to Hells Canyon Overlook, then after 30 miles, look for a sign to IMNAHA RIVER CAMPGROUNDS—that’s FS 39, and 7 miles later you’ll see the Hidden Campground sign to your right, entrance on your left.)"
