holiday adventure

bardzo proszę o sprawdzenie , z góry dziękuję : )
Holiday is a great time. Two weeks of my holiday I spent in Spain in Barcelona. I had a great time there. But one day I had terrible adventure. When I sailed on a canoe I fell off it. I thought that it was my end.
When me and my friend were in Barcelona we spent every our days on the beach. We sunbathed and swam in the sea. One day we borrowed canoe. The sun was shinning and the sky was clear. We sailed for one hour. In the sea were many big rocks. When we sailed close by one of this huge rock, big wave push down us on it. It was terrible because the canoe fell down and we fell off it. I was terrified because I can't swim. But I had a lot of lucky because I grabbed canoe very fast and got aboard it. When we calmed we sailed to waterside. But it wasn't end of my terrible adventures of this day. When I tried to got off from canoe I stamped on a sea urchin. I felt huge pain. With my friends help I went to the doctor. He removed thorns from my leg. After this adventure my leg hurt very much for two days.
In Spain I spent great time although this terrible adventures . I think that it was the best holiday in my life.
