Campsites near Helena 

This GEM of a Campground is one of my favorites! Located off Hwy 287 is Beaver Creek Rd. after you pass the Big Bull Bar & Grill on the corner you have about 5 miles of dirt road - you know you're close when you can see Canyon Ferry LakeGreat Fishing, boat ramp, dock, toilets, electric, and beach front campsites.
This place is another one of my favorites...
well, not this exact spot but close ;) You'll take the Wolf Creek exit 226 and follow Recreation Rd. it will convert into Craig Frontage Rd. you'll cross the Wolf Creek Bridge and turn right onto Beartooth Rd. and follow for about 5 milesStunning views of Holter Lake, boat ramp, dock slips, toilets, potable water, and plenty of shade for everyone
Riverside is located on Riverside Road just below Canyon Ferry Dam, off Jimtown Rd. Peaceful, quiet, serene campground that offers fishing, boat ramp, toilets, and more
Black and White Sandy are nestled in the Helena north valley secluded in the mountains right on the shore of the Mighty Missouri River and the Prickly Pear Creek.- Lake Helena Drive becomes Hauser Dam Road then you must choose - Branch Right for White Sandy - or - Left for Black SandyBoat ramps, docks, electricity, small dump station, water, but spotty service.
Goose Bay Lane off Hwy 284 is a long dirt road that leads to... you guessed it - Goose Bay Marina and Campground.
Very nice, clean, and a wide variety of campsitesThere's lots of dispersed first come first serve camping along the Canyon Ferry shore. A bit further you'll come to the general store and the camp sites with full hookups, boat slips/docks, boat ramp, dump station, handicap sites, toilets/showers, and plenty of parking
Located up York Rd. a few miles past the Lakeside market and gas station and just before the York Bridge Fishing access site. Not very dispersed, trees are scarce so not much shade but it's right on the Missouri River, very clean and a well maintained campground.Amenities include toilets, boat launch with boat slips and docks, potable water, electricity, etc.
Not as secluded as the last 3 and not as many amenities but for free spots you can't complain - Located off Hwy 284 is Lower Confederate Lane and a few miles down a bumpy dirt road you come to several signs that lead to different camp spots
Chinamen's is off Hwy 284 right between Court Sheriff and Kim's Marina
They have toilets, gravel boat ramp, potable water, although campsites are too small for any trailer over 20ft
Off Interstate-15 you'll take exit 234 towards Craig, after the exit you'll come to Bridge street that will take you through the small cute rustic town - Craig. Before the bridge you'll turn right on Frank Rd.There's a boat ramp, bathrooms, and a little further is a small campsite loop with a few campsites close to the shore.
Off Hwy 287 is a dirt road called Silos Rd. about a mile past the Silos Junction Bar & Grill are campsites or you can go further & have a multitude of lakeside campsitesAll the amenities a campground could have - KOA general store, dump station, multiple boat ramps, docks, boat parking (on land and water), toilets, potable water, electricity & sewage hookups
A bit of a drive on Hwy 284 will lead to you to Hellgate Campground Rd. following the dirt road a couple miles you'll come to a boat ramp with plenty of parking and a wide variety of different campsites lining the shores of Canyon Ferrybathrooms throughout, water, electric, group sites, many shady areas, beach fronts, and great views
