>>> CHECK THE LOCATION TAG AND
THOUGHT TO YOURSELF, MAN, I NEED
TO GO THERE ONE DAY.
THAT HAS A NAME IN THE TOURISM
INDUSTRY.
IT IS CALLED THE INSTAGRAM
EFFECT.
MORE THAN 1 BILLION USERS AND
ALL THEIR SELFIES HAVE TURNED
THE QUIET CORNERS OF THE WORLD
INTO THE HOTTEST TRAVEL SPOTS ON
EARTH.
KERI SANDERS VISITED ONE OF THEM
ON OUR "SPOTLIGHT."
>> Reporter: THE STUNNING LIGHT
SKIES IN COLORADO TO KEY WEST,
HOW ALL MANY PLAYERS NO MATTER
WHERE THEY ARE SNAP THAT SELFIE.
>> IT IS JUST KIND OF LIKE A
DIGITAL FOOTPRINT OF WHERE YOU
ARE AND WHAT YOU ARE DOING.
>> Reporter: THE PLACE TO BOTH
THESE DAYS IS INSTAGRAM WHICH IT
TURNS OUT ALSO DRIVES TOURISM TO
REMOTE LOCATIONS AND SOMETIMES
IT IS ALL ABOUT COPYING SOMEONE
ELSE'S BREATHTAKING POSE.
>> I LOVE SHARING A MOMENT LIKE
THAT WITH EVERYONE ESPECIALLY ON
INSTAGRAM.
TO BEST UNDERSTAND THE INSTAGRAM
EFFECT, WE COME HERE TO ICELAND.
142,000 TOURISTS CAME TO THIS
COUNTRY.
LAST YEAR MORE THAN 2 MILLION
SHOWED UP, MOSTLY FROM THE
UNITED STATES.
WE ARE NOT BIG POSTERS BUT AT
THE END OF AN ICE AND ADVENTURE
DAY, IT IS SO EXCITING.
>> ON THIS ISLAND NATION OF
DRAMATIC CONTRAST, NO FILTER OR
PHOTOSHOP NEEDED.
HERE, 1004 DEGREES BUBBLED TO
THE SURFACE.
WHAT'S IN
MORE SELFIES PER SQUARE FOOT
TAKEN HERE THAN ANYWHERE ON
EARTH.
>> I GUESS WE DID NOT KNOW IT
EXISTED UNTIL INSTAGRAM.
>> WE LOOKED AT THE IMAGES AND
HASHTAGS AND WE THOUGHT WELL,
LET'S GO THERE.
>> Reporter: IT USED TO BE
POSTCARDS BUT THIS IS THE GAME
CHANGER BECAUSE IT PINPOINT THE
EXACT LOCATION OF WHERE YOU ARE
AND YOU CAN SHARE THAT GEO TAG
AS IT IS CALLED ON SOCIAL MEDIA
WHICH ALLOWED THIS HIDDEN BEAUTY
TO BE SHARED WITH THE WORLD
WHICH IS GREAT UNTIL EVERYBODY
SHOWS UP.
>> WE HAVE SEEN GEO TAG PLAYING
A HUGE CULTURAL.
T
THE POPULAR ONES ARE GETTING
OVER RUN.
AN HOUR HIKE, LEADS US TO ONE OF
ICELAND'S MOST UNUSUAL GEO TAG.
THE CRASH THAT EVERYONE
SURVIVED.
>> IT IS NOT A NATURAL WONDER
THAT EVERY TIME SOMEBODY PUTS
GRAFFITI ON.
>> CONSERVATION AROUND THE WORLD
CONCERNS OF PHOTOGRAPHER OF GEO
TAGS PUTTING WILD ANIMALS AT
RISK.
THEY ARE ASKING TOURISTS TO SKIP
THOSE GEO TAGS.
>> I REALLY TRY NOT TO SPREAD
THE WORD OUT IN THE WORLD TO
PRESERVE CERTAIN SPOTS.
>> Reporter: HOW BAD HAS IT
GOTTEN?
IN SOME PARTS OF THE WORLD THERE
ARE TALKS RESTRICTING OF HOW
MANY TOURISTS.
>> IT IS A SIMPLE HASHTAG.
>> Reporter: BACK IN ICELAND, A
WARNING OF SOMETHING NEW OVER
TOU
TOURISM, FROM
