Grandhotel Pupp

Grandhotel Pupp is the iconic Karlovy Vary address — a monument to European bath culture that has hosted kings, composers, and film stars since 1701, and stood in for the casino in the 2006 James Bond film Casino Royale. The hotel runs a full-service spa with an indoor pool, a traditional sauna, a whirlpool, and access to the famous Karlovy Vary hot springs. The sauna at Grandhotel Pupp fits a hotel of this stature — a calm room inside a Belle Époque palace, paired naturally with deep tissue massages, facial treatments, and a stretched wellness sequence that uses the indoor pool and hot springs in turn. The hotel keeps a 9.2/10 rating across more than 1,000 Hotels.com reviews, a fair signal of how consistently the experience holds up. Grandhotel Pupp is the unambiguous choice in Karlovy Vary for travelers who want a sauna inside the most prestigious spa hotel in Czechia. The 228 rooms and suites are decorated in Belle Époque style, the elegant library is genuinely quiet, and the central position by the colonnades puts the mineral springs at the front door.
