There is no Lake Darling State Park in the state of Arkansas. However, there is a Lake Darling State Park in Iowa.

Lake Darling State Park is located in Washington County, Iowa and covers 1,417 acres. The park offers a variety of activities for visitors including camping, fishing, boating, hiking, and bird watching.

Some of the specific points of interest to see at Lake Darling State Park include Lake Darling itself, which is a man-made lake that covers 302 acres and is stocked with fish such as catfish, bluegill, crappie, and bass. The park also features several hiking trails, including the 4-mile Lakeshore Trail, which offers scenic views of the lake and surrounding woodlands.

One interesting fact about Lake Darling State Park is that it was named after J.N. "Ding" Darling, a Pulitzer Prize-winning political cartoonist and conservationist who was instrumental in the establishment of the park.

The best time of year to visit Lake Darling State Park is in the summer months, as this is when the weather is warmest and the lake is most popular for swimming, boating, and fishing. However, the park is open year-round and offers opportunities for winter sports such as cross-country skiing and ice fishing.
