Das Bad an den Kaiserthermen (formerly Trierer Stadtbad)

This is a clean, well-run facility with multiple pools in the center of Trier. At 7 PM on a weeknight, there were four 25-meter lanes set up for laps and enough room for all. The water temperature was on the cool side. Kickboards, pull buoys, etc. are not available: bring your own if you can.

There are two entry prices: a one-hour and a 3½ hour formula. Considering that the time starts from the moment you pay the entry fee, the one-hour rate might leave time for only a short swim.

They use an electronic bracelet system; the bracelet works as a key for both the lockers for your valuables (before entering the locker room) and the clothing lockers. You place the bracelet between the locker number and the red light to lock and unlock.

The parking lot behind the facility is free after 6 PM. A limited selection of caps, suits, and goggles is available for sale.

They keep only one lane separated from the rest of the pool with a lane line for laps, although people in the open section swim laps there, too. The pool is typically very busy in the afternoons.

Stadtbad Trier is greatly suited for workouts. There are several pools, one for schools and clubs, one for children and non-swimmers, one for diving, and one reserved for swimming only. In this latter pool, there is one lane reserved for "fast" swimmers (for people doing a workout and not just splashing around), and it's there almost all the time. You can enjoy some drinks or the not so big but very nice sauna (costs extra, 9€ for sauna and pool together).
