Visitor Comments About Hamilton County State Park
“Hamilton County State Park surprised us with its peaceful atmosphere and excellent fishing opportunities. We caught several largemouth bass right from our lakeside campsite! The trails around Dolan Lake offered beautiful views and we spotted deer every morning. Definitely a hidden gem in Southern Illinois.”
“We stayed in one of the small cabins for a weekend getaway and loved the experience. The park is well-maintained and the staff were helpful. The campground was quiet even though sites are somewhat close together. Bring your own food supplies as options are limited nearby. Perfect for disconnecting from technology!”
“As avid birdwatchers, we were delighted by the variety of species we observed during our three-day stay. The lake trail offers excellent viewing opportunities, especially early morning. Facilities are basic but clean. Would recommend bringing a good map as some trail markings could be improved.”
