Little Salt Marsh is part of Quivira National Wildlife Refuge in south central Kansas. This shallow inland salt marsh covers approximately 1,500 acres and is one of two major water bodies in the refuge. Water inflow comes from Rattlesnake Creek, which enters from the southwest and exits to the northeast. The marsh features a mosaic of pools, potholes, and hummocks, creating diverse wetland habitats.

Wildlife viewing opportunities abound at Little Salt Marsh. Migratory birds are particularly abundant, with over 300 species recorded. Spring and fall are peak seasons for observing shorebirds, waterfowl, and other migrants. Notable species include snow geese, whooping cranes, and various plovers and avocets. Bald eagles frequent the area in winter.

A wildlife observation tower is located on the south side of Little Salt Marsh, providing an elevated vantage point for birdwatching and photography. Two photography blinds are also available. A 14-mile auto tour route loops around the marsh, allowing for wildlife viewing from your vehicle.

Paddling is prohibited on Little Salt Marsh from April 15 to August 15 to protect nesting birds. Outside this period, paddlers should be aware that the marsh is very shallow, with high salt levels. Water control structures and levees are present along the northern edge of the marsh.

The refuge is open from 1.5 hours before sunrise to 1.5 hours after sunset. Visitor amenities include a nature trail with an elevated boardwalk across part of the marsh. Information kiosks are located throughout the refuge. The unique salt marsh ecosystem and abundant birdlife make Little Salt Marsh a distinctive paddling destination when watercraft are permitted.
