Translation of mastery in German

We returned to the former capital of the South at dawn and were dropped next to our place. We had a very nice day all in all, although it was very touristy. We felt that we have seen enough of the area.
We were considering flying to the same region again: we thought of going to Brazil, Venezuela or Guatemala. We were asking a lot of friends on their travel experiences to these countries.
One hour later, at sun set, we overflew the amazing Misti volcano which is located right above Arequipa. The mountain had a golden glow and its view was breathtaking.
