Boryeong (보령) is the gateway to the mud flats of Daecheon Beach and a strip dripping with Las Vegas–style neon, as well as the harbour in Daecheon-hang (2km down the road), from where ferries sail to a dozen islands. Few people stay in Boryeong proper, and instead travel 10km down the road to Daecheon Beach for what usually amounts to a woozy weekend of shellfish, soju (local vodka) and song.
The Boryeong Mud Festival is the big event here. Usually held in July, it's been recognised as Korea's top international festival, with more than a million attendees.
Navigating the Daecheon beachfront is easy. At the southern end of the strip, you'll find Citizen's Tower Plaza. Mud Plaza, a wide open space where many festival events take place, is about 1km north. In between, there are dozens of restaurants, motels and noraebang (karaoke rooms) on or near the main drag.
