Where the ground is warm
Thermal Europe
Europe sits on hot water in more places than people realise, and every culture that found some built something around it: Roman baths, Ottoman hammams, Habsburg spa towns, Icelandic municipal pools and a Finnish sauna in every building. Bathing is the oldest continuous European leisure activity there is.
8 places across 7 countries · not an itinerary
Bath
The only hot spring in Britain, plumbed by Romans and still running through their lead.
Budapest
A hundred springs under one city, and outdoor pools that are better in the snow.
Reykjavík
Neighbourhood geothermal pools, which is where Reykjavík actually socialises.
Helsinki
Public saunas returned to the waterfront, and the Baltic to jump into.
Bansko
Balkan mountain spa water, at a tenth of Alpine prices.
Baku
Not thermal but geological: fire that comes out of the ground and has for millennia.
Tbilisi
Sulphur baths under brick domes, an hour that costs less than a meal.
Höfn & Jökulsárlón
Not a spa: glacial water, and the point is how cold it is.
Not an itinerary
A theme is a way of seeing, not a route: these places are not in travelling order and most people take three or four of them, not all. For an order that respects distance, put the ones you want into the Planner.
