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.
Less than an hour from downtown Boise. Beautiful, scenic views, off the main road so it's mostly quiet. Tent only, but nicely maintained tent pads, fire rings and picnic tables. Perfect place to teach young ones the joy of camping; campground is open, mostly flat and easy to keep your eyes the tykes. One of the most enjoyable drives, ever.
Small campsite, approx 6-7 hard pads with vault toilet at one end. Site sits directly on a busy, paved roadway that follows Lucky Peak and Arrowrock Reservoir. Also, directly acro townss the street from RV camping is a busy, tent only campsite. The view of the River is nice, but the noise and outside distractions are not my cup of tea. But it's close to town, so there's that….
Flood Waters washed out the bridge that connects Hwy 21 to the campsite in 2016.
UPDATE: Grayback Gulch is OPEN and a wonderful little campground a short drive from Boise. No hookups, but the toilets are clean and there are two fresh water pumps. Fishing is available in nearby Moores Creek. If you can get a campsite along the north end, you may have walking access to a small stream that burps and gurgles down the hillside. There may be ATV traffic as it's a popular location for families. I really like using this as a quick 'getaway' overnight.
