The last weekend of May isn't a particularly good time, as that's the memorial Day weekend, a 3-day holiday. We like Eastern Washington for the additional warmth at that time of year. Highway 20 has will open by the end of this week after the final plowing.
There's a State Park close by Winthrop (Pearrygin SP) and a couple of private CGs too. At the eastern end of the Methow Valley is Alta Lake SP. A park we really enjoy is a County park near Lake Chelan, called Beebe Bridge County Park. It's on the side of the Columbia River about 5 miles from the town. There are a couple of other SPs along the river headed towards Wenatchee, and one close to downtown Wenatchee (Confluence SP).
Another private park we like is "Blue Shastin". It's about 7 miles south of Peshastin off Highway 97. It's riverfront on one of the smaller tributaries of the Wenatchee River, I think.
