Saunia Thermal Resort

Saunia Thermal Resort sits inside Hotel Thermal in central Karlovy Vary and centers on a pool filled with 100% natural thermal water drawn from the town's Vřídlo spring, held at 38°C year-round with a view out over the city. A separate large pool, kept around 32°C even in winter, is built for both swimming laps and lounging, with water attractions set into its perimeter for a slower pace.

The sauna world holds eight saunas and three types of cooling-down stations, connected directly to the thermal pool area. Daily sauna ceremonies are led by staff who compete at the national level, adding a structured, guided element to an otherwise self-directed sauna circuit.

Practical details are straightforward: towel and sheet rental is free, and swimwear can be bought at reception if it's forgotten. The first ten minutes in the changing room are free, and an evening rate applies daily from 18:00 for a 180-minute visit (not valid during special events like the Saunia Cup). Paying online before leaving speeds up checkout. Multi-visit passes covering ten full-day or ten three-hour entries, valid for six months, are sold at reception or online, including a non-transferable senior (60+) version; several Czech benefit and wellness cards are also accepted.

Entry is through the Hotel Thermal lobby, up to the first floor, then via a dedicated pool elevator to the Saunia reception. Paid parking is available at the hotel with a discount for guests who present their ticket at the Saunia desk, and the site is also reachable by bus to the I. P. Pavlova or U Jara stops. The resort is open daily from 09:00 to 23:00 and accepts walk-ins without a hotel stay required.
