We got a last second site and stayed for just one night. The sites were great for tents and relatively shady, but an RV had some trouble in our loop and had to move to another site. Where we set up our tent was pretty rocky and hurt the feet when you stood barefoot in the tent even with an extra tarp, so be careful where you set your tent.
There is no swimming beach, but the ranger gave us directions to another beach nearby. Next time we visit we'll be sure to check that out. Early June is good as the bugs there aren't bad at all.
The trails were nice, wish we had brought our bikes to hit the Sakatah/Singing Hills trail, looked lovely! The fishing dock was fun for the little kiddos to visit.
Wild River was a great campground, and only about an hour drive from the Twin Cities. The sites were nicely shaded and roomy for our tent and screen tent.
There is ample hiking, however due to early spring rains, many of the trails near the St. Croix were flooded, which is pretty typical for the river in the spring. We would have liked a swimming beach for the kids, but they enjoyed exploring the trails, especially the trail with a lookout over the river.
The great thing about June is that the bugs weren't bad at all. We escaped early in the morning due to impending rain, but found a lovely brunch spot on the way back to the cities.
We did one overnight at Savanna Portage State Park with my young children. The sites were smaller than we had hoped and we ended up moving to a new site, which they typically use for a group site and was much better to allow us to spread out and they even allowed us to park two vehicles up there. We enjoyed renting canoes for a bit in the afternoon and borrowed a kids activity kit. The bugs were pretty intense, a lot of mosquitoes, flies, and several wood ticks, so we recommend a screen tent for eating.
This is a nice and family friendly campground. We've camped in loops E and F and both are good. Most sides have some shade and trees and the picnic tables are in great condition! We were there over the 4th weekend and it was pretty busy, but everyone seemed respectful and the loud parties seemed mostly to be over at the beach. Lots of great paved trails surrounding the area, and Wargo nature center is only about 2.5 miles away, a bikable distance even for my 7 year old!
