You may have heard of Niagara Falls(尼亚加拉大瀑布), but do you know about the Niagara Escarpment(断崖)? It's a long steep slope(陡坡 that runs through the US and Canada. Earlier this month, our school (go) on a hiking trip to this beautiful place.

    The weather was cold; cloudy and windy, so we wore more (stay) warm. We (separate) into two groups and went on different routes(路线). The whole escarpment is 725 km long. But we only covered 8kin for about four (hour).

    My favorite part of the trail(小道) was the cave(山洞). The cave was formed from many different shaped rocks. Some were huge while the were small. We climbed down into the rocks the help of our teachers. The rocks were steep and slippery(滑的) they were covered with wet leaves. It was a fun and exciting experience for all of us.

    Another exciting moment was lunch. After (walk) 5km without any rest, we were hungry and tired.  our teacher finally said we could stop to have lunch ,we were very excited. After all, this trail was a little different from the ones I'm used to. It was (natural) than before.

    Hiking is very interesting, but remember to stay warm, stay hydrated(保持体内水分)and have fun along the way! With these, you couldn't enjoy it any more.
