Long Trek

It was in the Colca Canyon two years ago. I went there with three friends and my younger sister. It wasn't the first time I did had done a long trek as I had climbed the Misti Volcano a couple of months before.

I obviously didn't know the way or route we had to follow, so my friend helped us so much. He and was our guide.

We had been planning that trek a month before and we (this is not required as it is understood) only carried what we needed: walking sticks, hats, bags to cover our backpacks, good shoes, extra clothes, water, crackers, tuna and candies.

It Our hike lasted four days and we stayed overnight in some littles small towns where the price for a bed was only 5 soles per person. (these sentences were easily combined into one)

The landscape was beautiful, everything was green, pure the air was pure and there were many birds (bultur gryphus) and another animals. We crossed a river, the water which was cold and full because it was had been raining those for a few days.

Before we arrived at the end of the trail, we stopped in a small town called OASIS. There was It had a swimming pool and a beautiful view. After that we had to go up to Cabanaconde which is another Colca Town.

Finally, By the end we were too so tired even though Altought, I wanted to do it again.

Well done!  Just some minor revisions to your story.  I was also at the Colca Canyon in your country about 10 years ago.  I would have liked to do some hiking but didn't have the time as we were on a tour.  However, we were fortunate enough to see the famous Andean condor flying through the canyon.  An incredible sight!!
