     Climb the mountains was hard work but as we looked around us, we were surprising by the view. We

seemed be able to see for miles. At one point we were so high that we found ourselves cycling over clouds.

Then we began going down the hills. It was a great fun specially as it gradually became more warmer. In

the valleys colourful butterflies flowed around us and we saw many yaks and sheep eaten green grass. At

this point we had to change our caps, coats, gloves and trousers with T-shirts and shorts.
