Black Rock Campground was easy to get to in about 1.5 hours from the Boise area. The campground is small (11 sites) but nicely arranged with pit toilet and water crank pump station. Site 11 was nice and overlooked the North Fork Boise River. Shade was available until about 1 pm but the late afternoon sun was brutal until about 7 pm when the sun set behind the ridge. Suggest bringing a pop up canopy for this site. Plenty of downed pine sections available for firewood...but bring a splitting wedge and sledge hammer. Pit toilet was generally clean and had some paper...suggest bringing your own just in case. We did not see any snakes...but did get some enjoyment one morning watching a black bear forage on berry bushes across the river from us. Not many campers present when we were there, but folks were friendly, quiet, and kept to themselves. Spent the day fly fishing a 15 mi stretch of the river upstream from the campground. Rainbows were small (6 - 10"), but eager to take a fly all day long. Top flies were elk hair caddis, salmon fly, rubber leg stonefly nymphs, and zebra midges.
