Geode State Park, nestled in southeast Iowa near the town of Danville, is a picturesque 1,640-acre haven renowned for its abundance of geodes. Opened to the public in 1937 as one of Iowa's state parks, it has since attracted nature enthusiasts and rock collectors keen on discovering these unique geological formations.

The park's main feature is Lake Geode-a sparkling 187-acre lake that offers ample opportunities for fishing, boating, and swimming. Surrounding trails provide scenic hikes through diverse habitats including forests and prairies teeming with wildlife. The fall season brings vibrant foliage colors making it an especially popular time for visits.

Facilities within Geode State Park include campgrounds equipped with modern amenities such as showers and electric hookups catering to both tent camping and RVs. Picnic areas dotting the landscape make ideal spots for family gatherings or tranquil lunches amidst nature's beauty.

Located in southeast Iowa, the area now known as Geode State Park was once inhabited by Native American tribes. European settlers arrived in the 19th century, using the land primarily for agriculture and timber.

The park is named after its abundant geodes-round rocks with crystal-filled cavities-which are a geological feature of interest. In fact, it's one of few places where collectors can find these formations.

During the Great Depression era, specifically around 1933-34, workers from Civilian Conservation Corps (CCC) developed recreational facilities at this site which laid groundwork for future use as a public space.

Officially established in 1937 to preserve natural resources and provide recreation opportunities; over time amenities like camping sites were added enhancing visitor experience while maintaining conservation goals.

Lake Geode was created during this period through damming efforts aimed at providing additional outdoor activities such as fishing and boating.

Post-WWII saw increased leisure travel leading to more visitors enjoying picnicking areas along with swimming beaches that had been installed near Lake Geode.

In recent years there has been an emphasis on environmental education within parks including invasive species management programs designed to protect native ecosystems here.

There are 186 campsites with enough variety to suit anyone's tastes (96 sites have electricity). There are two modern shower buildings and a sewage dump station in the campground. Starting February 13, 2006 advance campsite reservations can be booked through the park reservation system. Half of the campsites are still available for self-registration on a first-come, first-serve basis. Two camp pads and rest rooms are accessible to the mobility-impaired.
