Translation of memorable in Spanish

After this strange stop we moved on to the city center where he left me. I was on my own now and started to explore the little streets of the old center. It was packed with international visitors.
I also made a reservation for a daytrip in the nearby mountains. We went in the early morning and met again near the Huanchan road, close to the office. A ten-seater picked us up and we left.
I chose a room in the center of town. I went to the northern beach of the island which was supposedly the most beautiful one. There were many young tourist lying in the sand but I still felt foreign.
