Last year l went on a nature hike with my friends. It was amazing experience. We saw lots of wild birds and we even swam in the river. We slept in tents, at night we heard weird noises but my friend Sarah said that these noises were absolutely normal for wildlife forest. At the end of our journey we saw something very scary. It was snake. I was packing my things when I saw it. I was shocked. Then I screamed loudly and ran to my friends. Fortunately we left this place and we have never come back.
