A quick 35 minute drive from Portland, Barton Park is an easy destination for family-friendly camping.
We camped here the first weekend in June with two other families, all with toddlers around the same age. The kids enjoyed the two playgrounds, wading in the river, and walking some nature trails. The park also offers horseshoe pits, volleyball courts and a boat ramp.
Our sites, 34 and 35, were joined together with a small path that let us use them more as a group site. Each was just large enough to accommodate two 4+ person tents with plenty of room left around the fire.
In the tent/rv loop, sites 1-30 are all in the open along the grass with no separation between them. Sites 31-59 are set back into the woods with a bit more privacy and separation— they're still pretty close together, but the woods and plantings help a lot.
All in all, it's a nice little county park. There are no sweeping vistas or old-growth forests to explore, but it's a simple spot to relax for the weekend.
