Murrells Inlet is an unincorporated area and census-designated place straddling the line between Horry and Georgetown Counties in South Carolina, United States. The community was once primarily a fishing village, but has grown substantially in modern time, along with the rest of the Grand Strand, into a popular tourist and retirement location. It is most known for the Murrells Inlet Marshwalk, a 1/2-mile-long (0.8 km) boardwalk overlooking a salt marsh and which houses many restaurants.
