There's Lake Constance, a big lake near the Alps with borders to the three countries Germany / Austria / Switzerland and listed in the book '1,000 Places to See Before You Die'. Coordinates are located on Island Mainau, Baden-Württemberg, Germany.
I decided to waymark this location on the little island Mainau because it's highlighted in the book.
Mainau (Germany)
Mainau is an island in Lake Constance (on the south shore of the Überlinger See near the city of Konstanz. It is maintained as a garden island and a model of excellent environmental practices. The island belongs to the Lennart Bernadotte-Stiftung an entity created by Prince Lennart Bernadotte, Count of Wisborg, originally a Prince of Sweden and Duke of Småland. It is one of the main tourist attractions of Lake Constance. Beside flowers there is a park landscape with views on the lake. There is also a greenhouse with tropical climate and thousands of butterflies.

Konstanz (Germany)
Lake Constance is a lake on the Rhine at the northern foot of the Alps, and consists of three bodies of water: the Obersee ("upper lake"), the Untersee ("lower lake"), and a connecting stretch of the Rhine, called the Seerhein. The lake is situated in Germany, Switzerland and Austria near the Alps. Its shorelines lie in the German states of Bavaria and Baden-Württemberg, the Austrian state of Vorarlberg, and the Swiss cantons of Thurgau, St Gallen and Schaffhausen. The river Rhine flows into the lake from the south, with its original course forming the Austro-Swiss border, and has its outflow of the "Lower Lake" where - except from Schaffhausen, see above - it forms the German-Swiss border until the city Basel.

Friedrichshafen (Germany)
Freshwater Lake Constance is central Europe's third largest, after Lake Balaton and Lake Geneva. It is 63 km (39 mi) long, and at its widest point, nearly 14 km (8.7 mi). It covers approximately 571 km² (220² mi), and is 395 m (1,296 ft) above sea level. The greatest depth is 252 metres (827 ft) in the middle of the eastern part (Obersee). Its volume is approximately 10×109 m³ (13×109 cu yd). The lake has four parts: the main section, called Obersee, 476 km² (184 sq mi); the north section, Überlinger See, 61 km2 (24² mi); the west section, Untersee, 63 km2 (24² mi); and the northwest section, the Zeller See and Gnadensee. The regulated Rhine flows into the lake in the southeast, through the Obersee, the city of Konstanz and the Untersee, and flows out near Stein am Rhein. Lake Constance provides fresh water to many cities in south Germany. The culminating point of the lake's drainage basin is the Tödi at 3,614 metres above sea level.

Bregenz (Austria)
The lake itself is an important drinking water source for southwestern Germany, called Bodensee-Wasserversorgung ("Lake Constance Water Supply"). Car ferries link Romanshorn to Friedrichshafen, and Konstanz to Meersburg. Lake Constance was formed by the Rhine Glacier during the ice age and is a zungenbecken lake. The Rhine, the Bregenzer Ache, and the Dornbirner Ache carry sediments from the Alps to the lake, thus gradually decreasing the depth and coastline extension of the lake in the southeast.

Romanshorn (Switzerland)
Lake Constance was first mentioned by the Roman geographer Pomponius Mela about 43 AD. He noted that the Rhine flows through two lakes, and gave them the Latin names Lacus Venetus (Obersee) and Lacus Acronius (Untersee). Pliny the Elder used the name Lacus Brigantinus, after the Roman city of Brigantium (today Bregenz). The lake is also colloquially known as the Swabian Sea.
The lake was frozen in the years 1077, 1326 (partial), 1378 (partial), 1435, 1465 (partial), 1477 (partial), 1491 (partial), 1517 (partial), 1571 (partial), 1573, 1600 (partial), 1684, 1695, 1709 (partial), 1795, 1830, 1880 (partial), and 1963.

Lindau / Meersburg / Uldingen (Germany)
Approximately 1,000 tonnes (1,100 short tons) of fish were caught by 150 professional fishermen in 2001 which was below the previous ten year average of 1,200 tonnes (1,300 short tons) per year. The Lake Constance trout (Salmo trutta) was almost extinct in the 1980s due to pollution, but thanks to protective measures they have made a significant return. Lake Constance was the home of the now extinct species of trout Salvelinus profundus, as well as of the Lake Constance whitefish (Coregonus gutturosus).
