    More Impressive Below Ground than Above Ground
    The Roman Baths are another of Trier's many UNESCO World Heritage Sites. There are a couple of impressive extant ruins above ground, but the really interesting stuff exists below ground. It is definitely worth a visit. I recommend renting an English audio guide, so you can listen to the history as you walk through the site. I imagine it would be even better with an actual tour guide, if you can book one.

    Impressive ruins but lacking information
    This site holds some potentially truly impressive ruins but a general lack of information holds it back from making an impact. The small exhibit explains the building in the context of the city and it’s history from planned Imperial baths to barracks. But when walking around the site itself, the paltry information means the visitor struggles to understand where they are within the site or what they are looking at.

    Surprised by how cool it was
    The Kaiserthermen site is really a must see. The site is more extensive than we imagined so carve out a couple hours for it. To enter costs about 5 euro and there are several sections to see. The first area is the visitor’s center which has a 3-d model and a short film about the site that helps you to see it as it must have been in its heyday. The next section to see is the tower from which you can see the whole complex. It is three levels with an elevator or stairs. The next part is the above ground section. An active archeological dig is going on so you can see that progress and there is very interesting interpretive signage in German and English. The ground is mostly grass and packed dirt so it’s not smooth but still accessible. The last section to see is the underground area which is like a maze—so fun! It is accessed only by stairs. Once below, there are open skylights but also harsh shadows so you might want to bring a small flashlight. There are many passageways and rooms but only a little signage. We went on a weekday in September and only saw a couple other people visiting the site.

    Impressive Roman Ruins
    The baths are well preserved and the largest we have seen anywhere. They were constructed in the early 4th century and never completed. We could go down some stairs to the complex of underground passages. The best view is on top of the tower giving a full view of these impressive ruins. A definite must see

I went here with friends. The ruins are impressive and the explanations are really nice (on signs). I think we spent 40 minutes here. The labyrint is nice to see and really cool (nice when you are there in the summer). It is nice but it has lots of constructions going on and therefore you see a lot of metal everywhere. This is a minus point.

4 € entrance fee per person, not worth it. There is one wall still left of what once was vast imperial baths, this wall on the east side of the property and easily visible without paying. Kaisertherman was built in early 4th century during Constantine’s reign. We did get to go underground, but now it's alley/tunnels. If you are here and needing something to do, you could easily walk around the park surrounding this place and have the same experience.

Didn't get to go in (looked cool from the outside).. the staff gladly (with a smile) showed off their rigidity when they turned away 5 customers at 5h31pm. The place is open till 6pm and the entrance had evidently been closed before the unadvertised "no more entry" time of 5h30pm.

While in Trier it is a must to visit the ancient Roman sights. The Kaiserthermen is an amazing piece of ancient Roman architecture and construction ability. Walk thru the tunnels and wonder how intelligent the people who built this truly were. There is a short video about the history before you begin your walk.

I’ve never been to Rome, so for me, this was fascinating. I especially liked walking through the tunnels below ground. The tunnel system was much more extensive than I would have guessed.
Although you can walk from Altstadt, we parked in the Basilica parking garage. It’s really close.

A true Labyrinth! Have seen half of them and finally found a way out. Must say, although built to be baths but only to serve a military site, this site is very impressive. The lady at the counter was not friendly at all, but never mind, the site makes it all up. Pitty is that the only room which had some recognisable features was blocked (and as it is not flooded with light hard to photograph). Of the Roman bath Palace from the 4th century, the walls of the thermal baths and the subterranean corridors system with fuel places for the heating preserved. When one enters the Imperial Baths, one will first come to the hot water bath (large enough for present-day theater and opera performances complete with stage, orchestra, and 650 seats). The incoming cold water was heated in altogether six boiler rooms, four of which are visible in the 19m high ruins which later served as a part of the medieval city wall. The 40° C/104° F hot water was then conducted into the three semicircular pools for the bathers. A hollow-floor heating system heated the pool floors as well as the rectangular central part of the vaulted hall. One can descend from here into the underground service tunnels and continue to the cold water bath.

The magnitude of the underground chambers at this site are unbelievable. A must see! There are a lot of renovations ongoing at the site so it is difficult to see and appreciate the tall exterior of the Kaiserthermen. There was a brochure in English to explain the site.
