Around this time last year I made a quick daytrip during a very hectic month to see the nearby Bonn. The best way to get your bearing and see some of the beauty of Bonn is to go to one of its several mountain top castles. I’ll mention two I’ve been to – Burg Drachenfels & Godesburg.
Burg Drachenfels is a bit out of town overlooking Bonn and the river from the east, and it’s where I was able to see a few balloons taking off from the main Bonn park.
Before that, I hiked a bit up the hill in the center of the old town to the Godesburg, a 13th century fort with panoramic views of Bonn from within the city.
