Hallyeohaesang National Park
Covering an area of more than 545.63 square km (210.67 square miles), this marine park has a rugged coastline, sandy beaches, sleepy islands, and lots of open water. The sanctuary is also home to myriad sea life including finless porpoises, otters, and the endangered Northern Pacific right whale. The real stars of the show are its scores of islands, including Saryangdo, Somaemuldo, and Bijindo, all of which are easy day trips via ferry from Tongyeong.
