Baden Baden  (meaning Bathing Bathing) is a spa town built on thermal springs at the edge of the Black Forest in Baden Württemberg, south west Germany. Don't be put off by its reputation as a hang-out for the rich. This picturesque town is beautifully situated in a wooded valley, and you can enjoy yourself here without spending or gambling a fortune.
The railway station is a 15 minutes' bus ride from the town center. It is served by Deutsche Bahn running north–south along the Rhine (Mannheim–Basel) and east–west (Munich–Stuttgart–Strasbourg–Paris). On arrival, catch the frequent bus 201 to the town center (direction Lichtental/Oberbeuern; get off at Leopoldplatz).
The airport Karlsruhe/Baden Baden (Baden-Airpark) is located only 10km from the city. The airport is served by low-cost carrier Ryanair, which offers cheap flights to several European destinations.
The town centre is small enough to walk around. Bus routes to surrounding towns and villages radiate from the town centre (Leopoldplatz and Augustaplatz). Buy your ticket at the machine at the bus stop before boarding. You can get also tickets from the bus drivers. It's rather to use the express busses. They need only 5 minutes from the main station to the city.
Römerplatz, the heart of the bath quarter (Badeviertel), is five minutes' walk from Leopoldplatz through the pedestrian zone. In Römerplatz you can see the ruins of the Roman baths and take to the thermal waters yourself at Caracalla Therme and Friedrichsbad. More details:

Friedrichsbad is a beautiful temple to traditional bathing culture, built in 1877, complete with statues and decorative tiling and culminating in a circular central pool in an ornate domed hall. In these elegant surroundings, the Roman-Irish bath (Römisch-Irisches Bad) is a programme of heat, massage, steam and water that will detoxify and rejuvenate any weary traveller. It's a wonderful, deeply relaxing experience. €21 for 3 hours (optional massage €8 extra). No children under 14.
The procedure at Friedrichsbad is unique, so read these instructions carefully before you go in, especially if you don't speak German. Buy your ticket at the entrance, plus a token for the soap-and-brush massage (Seifenbürstenmassage) if you want. At the top of the stairs, men and women go into separate changing rooms and follow the programme separately for the first hour or so. Take off all your clothes and put them in a locker, inserting your ticket into the slot inside the door before locking it. Naked, follow the sign to the baths, where an attendant will greet you. Follow the numbered sequence of rooms. Each room has a sign in English on the wall telling you how long you should spend there. You'll be given a towel and bath shoes at the first shower. You need these for the hot rooms (you must lie or sit on your towel). After the hot rooms, you reach the massage station, where you must hand back your towel, shoes and token. After the massage, proceed to the steam room(s) and shower again before going through to the pool area, where men and women bathe naked together in pools at three different temperatures. When you've had enough, head back via the cold plunge pool and the sleeping room, to be wrapped in blankets for half an hour. http://www.carasana.de/home/en/roemisch.html
There are plenty of cheap places to eat in the pedestrian zone in the town centre. Vegetarians need not despair. Noodle dishes (Spätzle) are ubiquitous, and look out for dishes based on chanterelle mushrooms (Pfifferlinge).
Free internet access is available at the public library (Stadtbücherei) in Lange Strasse, but you might need to book your session in advance.
