This is a beautiful park when it is not busy. Holidays are a nightmare because it is so crowded and noisy.The best times to stay are off season as they are unable to keep up the bathrooms when it gets busy. The cabins are nice but also do not recommend when the park is busy. The area itself is beautiful and the beach is awesome. Try to avoid the holidays as it becomes a "sardine can".
We have camped here for the last 3 summers and are returning again this year. This is a top notch campground, clean and quiet. The couple who manage the campground are awesome. I have a 13 yr. old boy with severe Autism and they have made his summers the best. We are from Illinois and have tried other places, but none beat Shamrock Park. This campground is the best in SW Michigan. Something for everyone, rustic, cabins, secluded, and pull throughs for "big rigs". There is a boat launch and charter fishing. This campground is open year round, and this year they are adding more bathrooms and pull through sites.
