Six miles of dirt road lead back to Boulder Campground, where two loops hold about 25 sites scattered through dense forest cover. The drive requires attention but remains manageable for most RVs and trailers, with campers reporting their rigs arrive in good condition despite the unpaved access.

Sites spread wide through the wooded loops, with the first loop offering particularly private spots tucked between mature trees. Most sites include fire rings with cooking grates, though spacing varies considerably. "Our campsite was a little cramped, the canopy from the camper was almost directly over the fire pit," notes Stephanie H., "but it was surrounded by trees and very private and quiet." The campground operates on a first-come, first-served basis, with roughly 14-16 sites typically filling up on busy weekends.

Hand-pumped well water serves the campground, though campers should expect somewhat discolored water from the iron-rich ground. Two pit toilet facilities stay well-stocked with supplies throughout the season. No electrical hookups exist, making this spot challenging for solar panel users due to heavy tree cover. Verizon provides two-bar coverage in many areas of the campground.

Hiking and biking trails extend for miles through the surrounding state forest, connecting to Lake Clayton and offering access to the St. Croix River. The campground provides boat launch access for canoes and small watercraft. ATV trails run along the entrance road for off-road enthusiasts. River access points appear at multiple locations along the drive in, with the Kettle River meeting the St. Croix downstream from the campground.

Boulder works well for campers comfortable with primitive facilities who prioritize privacy and forest access over modern conveniences. The $17 nightly fee reflects the basic amenities, with payment accepted via QR code or mail-in envelope system.

Visitors often highlighted spacious, secluded sites in a peaceful setting with clean facilities, though the campground offers primitive amenities with pit toilets and hand pumps. Some feedback indicated concerns about water quality and cramped spacing at certain sites.

Tents and small campers

Maybe 20 sites. No power. There's a hand pumped well, but the water is fairly brown. $17 per night. You can pay with an QR, or they have envelopes to mail the payment after you leave.

Great campground, will visit again.

We had an all around great time. The campsites were all pretty secluded. We got there around 10am on a Friday and there were a couple sites taken but the rest were up for grabs. (I believe there was 22 sites total) Out of 22 sites I’d say about 14-16 sites eventually got filled up as the park is first come first serve. Lake was clean. The road to the park had water access to the river as well. Lots of ATV and Hiking trails.

Great Campsite for car camping!

Well maintained campsites. All have fire rings and most have cooking grates. There are 2 bathrooms (outhouses) that were well stacked with toilet paper. Lake had a pull up area for boat launch or canoe. Excellent place!!!

Quiet, private and rustic!

There is about 6 miles of dirt road back to this campground, but it is a decent dirt road and my trailer was in good shape inside when we arrived. There are two loops (we only discovered the second one on our second day lol) with about 25 campsites total. No electric, water is available from pump and there are pit toilets. The campsites are private and quiet, especially in the first loop, which you enter through. We enjoyed the sense of camping 'away from it all' although it is a bit shady for solar panels to charge up the batteries. There are ATV trails along the dirt road on your way in, if that is your thing. We saw the ranger 1x, but the campground appears to be watched over, although not super closely. We enjoyed our stay here and would return. Also: Verizon Wireless signal 2 bars in many places.

Awesome!

Our campsite was a little cramped, the canopy from the camper was almost directly over the fire pit, but it was surrounded by trees and very private and quiet! The bathroom and showers were really nice. This park has miles and miles of great hiking and biking trails. We biked from the campground to Lake Clayton and even saw a bear on our ride! We rented canoes from the park and did the four hour canoe ride down the st Croix river which was super fun, I definitely recommend doing that. We also hiked along the kettle river to where it meets with the st Croix river and that was a cool hike

Large campground on the St. Croix river

Lots of room within the campground, beautiful hiking trails. Nice overlooks and hilly terrain to walk. The river is so peaceful here, so remember to bring bug spray cause you will need it.

Secluded camping close to town

There are some great secluded spots and the campground is always empty. It is definitely more primitive with pit toilets and hand pump wells.

My only complaint was how bad the mosquitos were... but it's Minnesota.
