Translation of possession in Spanish

The entrance hall where the passports were checked was renovated and had many ads for products from Western countries. Once we passed it and picked up our luggage we were looking for a ride into the city.

We had never seen a similar landscape. The lagoons had different kind of colors, blue, white, green and red. They were all surrounded by rocky, dark volcanoes making the entire landscape surreal.
