Small and crowded
Not the greatest campground, but ok overflow if you can't get into Lake Chelan State Park. Sites are very close together, it's nuts on the weekend, and the swimming area is a bit sad. Upsides include clean bathrooms and showers, nice dock, a small store, and it's right on Lake Chelan. Not a good value for the price though. Cost=$25-$35. Discovery Pass required, too. Reservable through Washington State Parks.
