IsLand has a mild oceanic climate throughout the
year with the smallest annual temperature range
in the country. The temperature for the hottest
summer months averages no more than 34.7¡Éand no
less than -1.5¡É for winter.
The island is 73km wide and 41km long with a total
area of 1,848 Jeju the largest island in South
Korea, came into existence 700 to 1,200 thousand
years ago when lava spewed from a sub-sea volcano
and surfaced above the waters. Then 100 to 300
thousand years ago, another volcanic eruption
formed Mt. Halla. The final volcanic eruption
that took place approximately 25 thousand years
ago created the crater lake, Baekrok-dam, at the
summit of the mountain.
Mt. Halla rises in the center of Jeju to 1950m
above sea level. The rest of the island slopes
down from its summit and is covered with dark
gray volcanic rocks and volcanic ash soil. Relatively
isolated from the rest of the world, the island¡¯s
nature has been well preserved in its prehistoric
state. That is why traveling to Jeju is to travel
back in time.
Jeju¡¯s natural environment has been preserved
as best as possible. The fantastically shaped
rocks decorating the seashores, the hundreds of
Oreums(secondary volcanos) and the rarest species
of flora around the Baekrok-dam lake are all treasures
waiting to be discovered by visitors. One cannot
see Jeju?unless one looks. It is like seeing only
trees before entering a forest.
