Which department is responsible for marketing South Carolina as a preferred vacation destination?

The South Carolina Department of Parks, Recreation, and Tourism is tasked with promoting the state as an attractive vacation destination. This department focuses on the management of state parks, recreation areas, and tourism-related activities. It plays a crucial role in marketing the diverse natural and cultural attractions of South Carolina, which can include beautiful beaches, historic sites, and outdoor recreational opportunities.

In contrast, the other departments mentioned have different focuses; for instance, the Department of Health is primarily concerned with public health concerns, the Department of Commerce is more focused on economic development and business support, and the Department of Environmental Control deals with environmental protection and regulatory issues. Therefore, the clear alignment of tourism promotion with the objectives of the Parks, Recreation, and Tourism department makes it the correct choice for this question.
