Read the following text and answer the question.

When I was first grade of senior high school, my friends and I visited Bali. We had a vacation for three days. I had many memorable experiences during my holiday.

On the first day, after arriving at the hotel, we checked in. Them, we visited Tanjung Benoa beach. There, we enjoyed many water sports such as banana boat, speed boat, jet sky, and many more. We also visited Penyu Island to see many unique animals. In the afternoon, we went to Kuta Beach to see the amazing sunset and enjoyed the beautiful day.

On the second day, we went to Sanur Beach as we really loved beach destinations. We went there in the morning since we wanted to witness the beautiful sunrise together. It was great scenery. I wish I could live there forever. After seeing the sunrise, we decided to go to Tanah Lot and met many tourists.

The last day, we spent our time in Sangeh. The green and shady forests were amazing. Many monkeys welcomed us along the street. They were not wild but sometimes they could be naughty and wanted to play with us. In the evening, we had to check out from the hotel and then prepared ourselves to go back home. I love Bali so much!
