2 Best Sights in Berlin, Germany

Germans love their thermal baths and saunas, and this is one of the classiest around. The dramatic main thermal pool lies under a vaulted ceiling, where glowing lights and soothing music that can be heard underwater enhance a feeling of calm. In addition to several saunas and a steam room, take advantage of the outdoor hot tub in the enclosed courtyard, best at night under stars. There's a bar and a healthy snack menu, just in case all that relaxation leaves you hungry. Full nudity is to be expected here, even in coed areas.

In a city dotted with lakes, pools, and thermal baths, this is one of the most attractive public bathing spots, a neoclassical beauty built in 1914 and renovated in 2009. Even if you don’t plan on taking a dip, it’s worth a peek: the unremarkable, gray concrete exterior, which seems designed to ward off tourists, conceals two stunning swimming halls, their pristine pools lined with columns and decorated with elaborate mosaics and gargoyles spouting water. To make the most of it, get a day pass for the pools and multiple saunas. Monday is women-only day in the sauna and Sunday evenings are nude-only (FKK).
