How to write my composition about going skating on the beach?

Arriving in White Sand Dunes happens to be the most beautiful time of the day. In the endless sky, there are several white clouds floating slowly. The sky is blue and the white clouds are white. At the junction of heaven and earth, there is a sand dune, and the sand dune is also white. No wonder it's White Sand Dunes.

The tour guide said that we were going to play sand skiing in the sand dunes, and we all jumped for joy. Facing the wind, we ran into the arms of the sand. We built sand castles, kicked sand and had a good time. The guide took us to play while walking. Came to the bottom of the sand dune, ready to rush up. It's so hot to step on barefoot! Do you know that there is a hot sun above my head and a "boiling sea of fire" under my feet! Now that I think about it, I still sweat all over.
