Koblenz has about 110,000 inhabitants (2015); the surrounding area accounts for about 400,000 people in total.
The name Koblenz originates from Latin (ad) confluentes, confluence or "(at the) merging of rivers". Subsequently it was Covelenz and Cobelenz. In the local dialect the name is Kowelenz.
After Mainz and Ludwigshafen am Rhein, it is the third largest city in Rhineland-Palatinate in terms of population. Koblenz lies in the Rhineland, 92 kilometers (57 mi) southeast of Cologne by rail.
Koblenz can easily be reached by train, for example from the Frankfurt/Mainz area, Cologne area or Trier. These towns are one to two hours away and connections run from early in the morning till late night.
Three German motorways lead to Koblenz: A3, A48 and A61. Parking in the centre of Koblenz is sometimes restricted according to time. Park and ride is available. The train station has a parking garage, as do both shopping malls (Löhr Center and Forum). Pay attention to closing times: mall parking garages close shortly after the shops, typically catching at least a few tourists unaware.
The bus might be the cheaptest option for travelers who want to get to Koblenz from another German city.
There are two long-distance bus companies offering routes to and from Koblenz daily (FlixBus & Mein Fernbus).
Tickets have to be booked in advance and online.
If still available, tickets can also be purchased directly at the bus station (near the central train station) but the prices will be significantly higher.
There is also the option to do carpooling. The most popular website for carpooling in Germany is Mitfahrgelegenheit.de  (abbreviated to MFG).
Requires a cell phone and sometimes some knowledge of German.

Deutsches Eck. This spot (the name means German Corner in German) is where the Mosel River meets the Rhein River. The tip of the park is shaped like a ship's prow, overlooked by an enormous equestrian statue of Kaiser Wilhelm mounted on an equally-huge stone base that you can climb for a great view of the rivers and opposite shore castle/fort. Not far from the German Corner, you can catch a little sightseeing train which will drive around & point out some of the interesting things about Koblenz.

Militär Museum. This is a big military museum. It is located on the other side of the Mosel. In the past Koblenz was an important strategic military area. On every side of the rivers were military castles/forts. Rivers were the most important logistic routes until the 20th century. Their possession could decide who won or lost a war.
Schängel-Brunnen. This is a nice little fountain near the town hall. You should stand three steps in front of the fountain and in front of the figure's face. Wait there three minutes. What then happens should bring fortune.
City Sculptures. Koblenz has a number of whimsical sculptures and fountains scattered throughout the city. Look for them as you walk around, and you will be pleasantly surprised.

Koblenz is located in the wine area of the Rhine and Mosel Rivers, mostly known for dry white wines, but also producing dry red wines, and in Germany, trying the beer is also a must.
