There are showers at Abalone Campground as well. My experience has been that it's busier on weekends than weekdays. Early mornings and late afternoons seemed the least busiest. You could call the park and ask as well, they were extremely helpful.
2 showers on the men's side...handicap shower and bathroom in back and I believe 2 more on the women's side. One handicap shower and bathroom is closed for repairs. Unless the campground is packed to the gills, the showers are usually open. Hope this helps you!
