Quick answer: In December and January Karlovy Vary is fully operational — the spa district, colonnades, springs, sanatoria and restaurants all run as normal. The highlight of December is the Christmas Market (29 November – 6 January). Far fewer tourists, lower prices, no queues. Cold: –2 to +5°C, snow possible. Worth the trip — especially if you want peace, thermal treatments and atmosphere without the summer crowds.
Karlovy Vary is a year-round resort. The hot springs rise at 41–73°C regardless of the season, sanatoria are open, treatments are prescribed. Winter here is not a closed season — it is a different mode: quieter, cosier, and for many visitors preferable.
December is special: the spa promenade glowing with Christmas lights, the market by the Mill Colonnade, the smell of trdelník, the road train in festive livery. January is quieter still — almost monastic, with full focus on the waters.
| Month | Daytime | Night | Snow |
|---|---|---|---|
| December | +1…+5°C | –3…0°C | ~8 snowy days |
| January | –1…+3°C | –5…–1°C | 10–12 snowy days |
The spa promenade sits in the Teplá valley — cold air lingers and morning fog in January is normal. The colonnades provide shelter from the wind. Snow falls but usually doesn’t settle for more than a few days.
Daylight: around 8 hours in December, 9–10 hours in January. Plan your sightseeing for the morning; evenings are for treatments or dinner.
All colonnades are accessible. The Mill, Market and Park Colonnades are open 24/7, free entry. Spring water is free to drink year-round.
Hot Spring Colonnade (Vřídelní kolonáda) is open 06:30–18:00 in winter (until 19:00 in summer). The Castle Colonnade is accessible to guests of the Zámecké Lázně spa only.
Sanatoria operate on their full schedule. Winter is traditionally a peak season for treatment stays: 14–21 days, full medical programme. Some hotels offer short winter spa breaks of 3–5 days.
Indoor pools, steam rooms, hammams — all open. Thermal treatments with mineral water take place in enclosed facilities.
The funicular to Diana runs on winter hours, approximately every 15 minutes. The lookout tower is open. The view over the snow-covered town at dusk is one of the finest in the region. On foot it is 15 minutes from the Mill Colonnade.
Most restaurants in the spa zone operate without interruption. Some venues in residential neighbourhoods may reduce their hours over the holidays (24–26 December). Book ahead for Christmas Eve and Christmas Day.
29 November to 6 January — market by the Mill Colonnade, open daily, free entry. Full details in our Christmas Market in Karlovy Vary 2026 article.
2–23 December — festive road train on Fridays, Saturdays and Sundays. 50 CZK, children under 15 free. Route through the spa district, ride ~1 hour. Details: Tourist Road Train in Karlovy Vary.

December is high season; the Christmas week (23–27 December) is very high season — hotels full, prices at or above summer levels. From 7 January the drop is sharp: few tourists, hotel prices 20–40% lower than summer, no queues at the springs, uncrowded restaurants.
Book well ahead for December, especially the Christmas week. January can be booked 1–2 weeks out without losing choice.

How cold is it in Karlovy Vary in winter? Cold but manageable: December averages +1 to +5°C in the daytime, January nights can reach –3°C. Snow is possible but rarely settles for long. The colonnades and covered galleries give shelter. Dress in layers and bring waterproof shoes.
