Burgplatz is where the little River Düssel, which gave the town its name, flows into the Rhine. In the background is the former collegiate church, St. Lambertus, with the shrine of St. Apolinaris. Next to the bridge over the Düssel, the monument to Düsseldorf being granted the privileges of a town demonstrates impressively more than 725 years of town history (town status granted in 1288). The square is dominated by Alter Schlossturm, the old palace tower (now the Schifffahrt-Museum navigation museum) and last testimony to the princely palace from the 13th century that fell victim to flames in 1872. The generously proportioned Rhine embankment promenade is considered one of the most beautiful on the Rhine. Upriver, the Medien Hafen is characterised by outstanding architectural creations, and the elegant district of Oberkassel on the opposite bank by art-nouveau facades.

The Botanical Garden of the Heinrich-Heine University is situated in the south of Düsseldorf at the Himmelgeister Rheinbogen (bend in the Rhine). As a research facility, it is not only dedicated to research and teaching, but also open to visitors throughout the year and offers a wide range of events including exhibitions, expert guided tours and lectures.

Walk through the Tegallalang Rice Terrace, about 20 minutes north of Ubud. It's a steep, stepped landscape shaped by the traditional subak irrigation system, which keeps the fields bright green for most of the year. Go early to beat the heat and crowds. There are swings, zip lines, and cafés on the edges, but the best part is just following the narrow paths through the terraces and taking it all in.
