About Myrtle Beach, SC

A Horry County city myrtle beach has a population of 34,695. It is a tourist destination owing to its coastal connection. It is the center of a large beach area The Grand Strand along the east coast of the country. It earned the second rank as the fastest-growing metropolitan in the country. Tourism first started as a weekend outing for the lumber and railroad employees here. These were the first Grand Strand tourists. Then it was developed into a beach resort to rival those in the north-eastern area and Florida. The beach derived its name from the locally grown shrub myrtle. A military base was set up here after the development of the Myrtle Beach Airport. This steered development and attracted tourists. It is home to the Gay Dolphin Gift Cove, the country’s largest gift shop. The myrtle beach souvenirs and seashells sold here are in great demand.
