Best Dog-Friendly Camping near Marine on St. Croix, MN

We traveled to this state park for our annual girls weekend camping trip. We stayed @ campsite 113 in the Savana campground.

The park was absolutely gorgeous and we truly had a wonderful time! Location wise the park itself was super convenient - it was close to the cities, we got there in under an hour from where we live (near Chaska).

There were plenty of trails to explore and our campsite had plenty of room. Although there were a lot of people staying at the park when we went, we didn’t feel very cramped for space.

We stayed in the Savana campground which was really nice. However, if we were to come back I think we’d opt to stay in the Riverway campground. It was really gorgeous down by the river. We walked the riverside loop trail and really enjoyed it!

It was also really fun being close to Stillwater and Marine on St. Croix. The weekend that we camped, the weather was less than par- cold and rainy for most of it! So we spent a couple hours at the winery in Stillwater to warm up :)

William O'Brien has two different campgrounds and we ended up staying at Savannah, and it was a really nice little campground. Most sites are relatively secluded, except mine which was kind of wide open and the location of a firewood drop box (74E). It was super large, though, so if there was a bigger party you could easily fit a few tents. The campground was really nice, but I'd probably pick a different site next time. 

The hiking at the park was fantastic. We did one longer hike that had some surprisingly good views. It was hillier than I thought it would be - not a tough hike, but hillier in that you could experience some nice views. The second day we did the river side hike, which was also very pretty but was also much more popular. I'd recommend an early morning visit to that one, especially during these Covid times.

Unrelated to the park, if you forgot any supplies, the general store in Marine on St. Croix was adorable and had really good sandwiches. Like another review said, either way I'd recommend driving in from that way regardless - the winding road and the tree canopy is really pretty.

My first time solo camping was at William O'Brien State Park on a Sunday evening. Weekends have been packed and reservations scarce for months at state parks in Minnesota. Arriving on a Sunday afternoon was a dream—very few people in the campground loop (especially the non-electric ones), but still able to take advantage of a weekend day.

Per others' advice, I stayed at Savannah campground because the sites are slightly bigger and more private than Riverway. Compared to Wild River State Park, the sites at Savannah are pretty cramped with inconsistent vegetation between sites. I wouldn't want to stay here when the loop is fully reserved. On a Sunday evening with only one other site reserved, it felt like I had the place to myself.

Site 117 was level, had decent privacy, and was more spacious than some of the other sites (could have put up a 3-5 person tent and a bug house). The fire pit was clean and had a grate on top. There were trees to hang a hammock. The hiking trail was about 500' away, and you could hear the occasional hiker. When the wind died down, you could also occasionally hear the loud motorcycles on the highway. Water was easy to access, but the pit toilet is in the next loop over. If I stayed again, I might try site 121 or 123 since they have more privacy.

Sites 98, 110, 111, 112, 113, and 114 are right on the road into the campground with some tree coverage and prairie behind. These do not feel very private at all.

A couple random notes: 

• Firewood is $6/bundle. Self-pay available at site 74e if the ranger station is closed. Bring exact change since you'll be paying by envelope.
• Cell reception for T-Mobile was minimal to non-existent. Wifi is available in the visitor center parking lot.
• Do yourself a favor and arrive in Marine on St. Croix via Broadway Street / Maple Street. The tree canopy, winding roads, and tunnel are worth it.

This is a state park on the Wisconsin side of the St Croix River, which is mirrored by a comparable but smaller state park in Minnesota on the wrst side of the river, both being part of the wild and scenic St Croix National Waterway. Although the campsites themselves are pretty run of the mill, the setting is spectacular in terms of breathtaking scenery, and myriad outdoor activities from rock climbing in the river gorge, paddling the river, hiking miles of trails, and learning geology at the Ice Age geology visitors center. If you are tenting camping, the south loop is great, and if you pick campsite 65 or 67 you will have direct access to the river which is peaceful and good for paddle opportunities. There are picnic areas with swimming along the river which is nice for group gatherings, and one is designated for folks with pets. Some of the rugged hiking trails along the bluffs and cliffs go right along the edge with minimal guard rails or walls, so keep a close eye on kids and pets because going over the edge is a possibility so utmost caution is advised.
