Kaiserthermen

This Roman ruin is surprisingly easily accessible considering its ticket price, less crowd, and close distance from the town center. Entrance is located at the Southern-west end of the palace garden. Walking through the underground isles makes you feel like you're exploring in dungeons. I brought my kids here and they really enjoyed walking here. The only disappointment is the minimal explanation available on site except the pamphlets you get at the entrance. However imagining how people would have used this place is also very fun. Similar ruins in southern Europe would be much more crowded, I presume. Nearby parking is easily accessible, too.

A well preserved living museum. Easy to find, and a short walk from other tourist sites. No immediate parking, but good clean toilets and friendly staff. 6 euro for an adult entry, which is well worth it. The history is well preserved and incredible to walk around. There are also modern overview points and history boards

This is such an easy place to stop by quickly and check out such a historical Roman ruin and it’s only a few euros to get in. You can see everything in less than an hour and it’s quite amazing to walk through the tunnels and see the historic remains at this active archaeological site. Definitely take the time to stop by and check this amazing place out.

Great Place to Visit if you find yourself in Trier. Tickets are pretty cheap and the underground passageways are exciting to explore.

Very amazing to walk in the tunnels underground. So crazy to think that the walls are almost a thousand years old. Very worthwhile to go visit.

Great place but we missed more information in English

There was no waiting time or queue when we went in. Tickets were around €5 or €7 for two people which is not bad at all. You could easily spend there 1h-2h exploring the underground’s. I would highly recommend to visit while you’re in Trier.

Impressive enough to see it from outside. Stunning! Entry cost 6€
