We are on a big boat today.
The boat leaves from Cairns in Australia.
We are going to the Great Barrier Reef.
The sun is hot and the sky is blue.
We wear lots of sunscreen to protect our skin.
Soon, the boat stops in the deep ocean.
We put on our masks and jump in.
The water is very clear and warm.
Under the water, we see a beautiful world.
There is a lot of colorful coral here.
I see bright yellow and blue fish everywhere.
They swim very fast around the coral.
Suddenly, my friend points at something big.
It is a beautiful green sea turtle!
The turtle swims slowly past our group.
We watch it for a long time.
Snorkeling on the reef is an amazing experience.
We will take many pictures on the way back.
We will never forget this wonderful trip.
