Black Rock CG is a great spot along the North Fork of the Boise River, and I've had some enjoyable trips there. What wasn't enjoyable this time around was the camper nearby who ran a generator all day long and stayed in their trailer. I have an idea that I'm hoping to promote to the Forest Service -- designate campgrounds similar to Black Rock as 'quiet'. No generators, etc. -- nature has a beautiful soundtrack of its own.

Great time. Outhouse gets used a lot so bring your own wipes.

Beautiful site! We stayed at site 1 which is right by the river. Listening to the river at night was amazing. Site was clean. We RV camped.

The campers ahead of me didn't leave until 2:00pm. They weren't even apologetic.
