Turtle Rock was given its name for its rock formation that resembles the shape of turtles climbing out to the rock. The Turtle Rock is a volcanic rock that formed from the molten lava from Ulleungdo Island's early volcanic activity. Solidified lava flow as well as chilled margins can still be seen along the rock's slope. The western cliff of the rock is Tonggumi Village, where it serves as a home to wild juniper trees. On the northwestern side of the rock is Daepunggam Village, also a natural habitat for wild juniper trees. Both sites were designated as Natural Monuments for their significance. The juniper trees here are known to have a slower growth rate than those under normal condition due to rough winds.
