Translation of brochure in Spanish

In the end we went up to the tower. We have never climbed so steep stairs ever before and once up we were really afraid to go down. There were no safety installation at this tower.
After ten minutes and after drinking a bottle of water we returned to our place. It was already three in the morning. We were unhappy to miss a great party, but our physical conditions were bad.
The next day we had to take the bus in order to get back to the airport in Calama. When we arrived at the airport was empty and no counter was open yet. We had to wait for 4 hours.
