Terrific campground near Idaho City

The tall pines provided ample shade from the hot August sun. The sight was very clean and accessible. We went to the rodeo and had a great time visiting.

Great Spot in nature, one hour from Boise

THE BRIDGE IS OPEN.  Grayback aka Grayback Gulch CG was closed for a few seasons while the bridge entering the park was replaced.  Pros: I like this little CG; good spacing between sites, clean toilets, potable water and plenty of hiking and fishing opportunities nearby.   I can leave Boise and be on-site in about an hour. Cons: It's close enough to Hwy 21 that you can hear the bigger trucks, very popular ATV/UTV trail head, so expect a little noise and road dust.
