2 Best Sights in Berlin, Germany

The name of this tiny island is translated as “Island of Youth.” Nestled into a bend in the Spree River between Treptow and the Alt-Stralau peninsula, it was the scene of a youth club during GDR times. Although its heyday is past, there is something dreamy, if not a bit creepy, about the island. It can only be accessed via a narrow, arched footbridge from Treptower Park, so it's devoid of cars, noise, and even much foot traffic. Visitors can enjoy a picnic on the docks, or rent paddleboats and canoes. In the evening, the club Insel Berlin hosts concerts, film screenings, and parties (the club also runs the beer garden and café).

Prussian king Friedrich Wilhelm II whisked his mistresses away to this small island oasis on the Great Wannsee. Schloss Pfaueninsel, the small white palace, erected in 1794 according to the ruler's plans—and in accordance with the taste of the era—was built as a fake ruin. The simple building looks strangely cartoonlike; you can see the interior on half-hour tours. In the early 19th-century, garden architect Joseph Peter Lenné designed an English garden on the island, which ultimately became western Berlin's favorite summer getaway. The park, which is designated as a UNESCO World Heritage Site, is now a nature reseve.
