We go here once a summer for the past 30-ish years. I love the rocky beaches, and the beach combing is the best. We have found may different color of beach glass along with fossils and many unknown oddities. The campground is clean and the campsites are large and shady. It's a bit of a hike from the campground to the beach, but if it's too long for you driving is an option. Many restaurants in nearby South Haven along with a maritime museum and tall ship rides. Weekends fill up fast, but you'll want to spend more than two days anyway!
Lovely campground right on the shores of Lake Michigan. I accidentally booked a primitive site online, but as it turned out that didn't matter as a storm had ravaged the area the day before and there was no electricity anyway. All of the employees were exceptionally nice, even with the less-than-optimum circumstances. I can't speak to the amenities since the store was closed and we were only using the pit toilets (which were cleaned daily) but between walking along the lake, and playing cards at our campsite (which we had all to ourselves!) we had a very enjoyable time.
