THE GREAT BARRIER REEF, AUSTRALIA
Nicky has just come back from her fantastic trip to the
biggest coral reef on Earth. She says, "The reef is 2,000
km long. I've heard that you can even see it from space! I
swam with dolphins and turtles. It was thrilling. There are
also over 1,500 species of colourful fish on the reef and
they aren't afraid of curious divers. I've taken some
amazing underwater photos!"
MACHU PICCHU, PERU
Mary has just been on the Inca Trail', a famous jungle hike to the Lost
City of the Incas Mary tells us, "Machu Picchu is an ancient city in the
mountains, 2,430 metres above sea level. The 4-day journey up was
challenging and amazing! There were spectacular mountain views and
rare wildlife-I even saw a hummingbird! People say the ruins were a
holiday resort for rich Incas. The Incas built temples, houses and parks
and time hasn't destroyed many of them. It's a very mysterious place
because nobody knows why the Incas left. I had a brilliant time!"
ALTYN EMEL, KAZAKHSTAN
Not many people can say they've visited a singing hill. Kanat has done that! "The
singing dune is a really unique place," he explains. "You drive along a track, and
among several trees, you can see eagles, lizards and wild donkeys. Then, you see
three tall stones. A legend says that Shyngys Khan put them there, 800 years ago.
When you arrive at the tall dune, you walk to the top and as you slide down, it
starts to make a loud and beautiful 'singing' sound! In the past, the area was
covered in apple forests. It's my new favourite place!"
