When most people think of hot springs in Europe, Iceland usually comes to mind. And yes, we get it: the Blue Lagoon is world-famous for a reason. But Europe is brimming with hidden thermal spas and secluded hot springs that offer just as much, if not more, for those looking to escape the crowds and indulge in some self-care. These lesser-known gems, tucked away in beautiful landscapes, offer the perfect combination of relaxation, nature, and healing minerals - all at a more peaceful pace. So, pack your swimsuit, and let’s take a trip to some of Europe’s most tranquil, secret hot springs.

Terme di Saturnia, Italy

If you’re craving an easy, no-fuss escape, Terme di Saturnia in southern Tuscany is worth bookmarking. The warm, sulfur-rich waters have been flowing here for thousands of years, and they’re still free to visit. The main attraction (Cascate del Mulino) is a series of natural limestone pools where the water stays around 37°C year-round. It’s warm, soothing, and surprisingly relaxing even in cooler spring months.

This isn’t a polished spa: it’s more rustic, more real. There are no changing rooms or lockers, just locals and travelers soaking in nature. It’s open 24/7, and the water never stops flowing.

Just a head up… it can get busy, especially midday and on weekends. If you want a quieter experience, come early in the morning (sunrise is magical here) or later in the evening after the daytrippers have left. Weekdays are best.

Bring water shoes (the rocks are slippery), a dark towel (the sulfur smell tends to linger), and wear your swimsuit under your clothes. You’ll also want to pack a dry bag for your stuff - there’s nowhere to leave valuables safely.

Need a coffee or lunch after?
Walk over to La Baracchina just nearby for a casual meal and a break in the shade. Or, if you’re looking for a more peaceful soak, you can book a day pass at the nearby Terme di Saturnia Resort, where you’ll find thermal pools, spa treatments, and a more private vibe.

How to get there:
Fly into Rome or Florence, rent a car, and take the scenic 2–2.5 hour drive to Saturnia. A car is definitely needed - not just for the springs but for exploring nearby hill towns like Pitigliano or Sovana while you’re here.

Want a quieter soak?
The upscale Terme di Saturnia Resort is just down the road and has private pools if you want something calmer and more spa-like. But honestly, the public springs are just as special—more rustic, but very real.

The Blue Lagoon of France: Bains de Baracci, Corsica

Corsica isn’t usually the first place people think of when it comes to thermal springs - and that’s exactly why Bains de Baracci feels so special. Tucked into the hills just outside Propriano, on the island’s quieter western coast, these thermal springs are rustic, peaceful, and surrounded by greenery. If you’re someone who loves slow travel and simple pleasures, this might be one of your favorite stops.

You won’t find luxury resorts or sleek spas here - just an outdoor pool filled with naturally warm, mineral-rich water and views of Corsican hills all around. The atmosphere is super laid-back. Locals often come here during the week, especially in the mornings, which are the quietest. It’s the kind of place where you can just sit, soak, and breathe deeply without feeling like you’re on display or fighting for space.

There’s also a small indoor section with a couple of spa tubs and a basic changing area, but most people skip straight to the outdoor thermal pool. It’s simple, slightly old-school, and that’s part of its charm.

What to know before you go:
– Bring your own towel, water bottle, and flip-flops. There’s not much available on-site.
– The facilities are minimal—don’t expect robes or wellness smoothies, and that’s kind of the point.
– It can get busier on weekends, especially in summer, so go early or visit off-season for the calmest experience.
– Entry is affordable (usually under €10), making it a great wellness stop even on a budget.

After your soak, head into Propriano for lunch by the marina. It’s a sleepy little town, but it has enough cafés and restaurants to keep you fed and happy. If you’re staying nearby, consider Olmeto: a peaceful village on the hillside, full of small guesthouses with sea views, homemade food, and that classic Corsican slowness.

Aachen Thermal Baths, Germany

If you’re craving a wellness escape that comes with a side of culture, Aachen might be your spot. This small German city sits right on the border with Belgium and the Netherlands, and it’s been known for its thermal waters since Roman times. Unlike the flashy spas that dominate your feed, Aachen’s baths are quieter, more rooted in history, and surprisingly easy to reach.

The Carolus Thermen is the main thermal spa here, and it’s beautifully done: sleek but calming, with a series of indoor and outdoor pools filled with warm, mineral-rich water. You’ll find whirlpools, saunas, and steam rooms, but without the “wellness influencer” vibe. It feels more local, more grounded.

One thing that makes Aachen stand out is that the spa sits just minutes from the old town. You can spend the morning soaking in geothermal pools, and by afternoon, be wandering through cobbled streets, sipping coffee in a sunny square, or visiting the UNESCO-listed Aachen Cathedral—a gothic gem that dates back over 1,200 years.

Things to know before you go:
– Carolus Thermen has a full sauna section (textile-free), but you can stick to the thermal pool area if that’s more your speed.
– Weekdays are quieter, especially before noon.
– Bring flip-flops and a towel, or rent them on-site if you’re traveling light.
– Some areas are adult-only, which keeps the vibe relaxed and calm.

Aachen feels like the kind of place where everything moves at the right pace. You can easily do a slow stroll through the town center, pop into independent bookshops or bakeries, and then head back for another round of soaking. It’s not a flashy destination, but that’s exactly why it works.

If you're staying overnight, look for boutique guesthouses or design hotels close to the old town—you’ll be within walking distance of everything.

Bath, United Kingdom

If you’ve ever dreamed of soaking in a hot spring with views over a golden-stone city, Bath might be your answer. While most people know it for the ancient Roman Baths (which you can visit but not swim in), the Thermae Bath Spa gives you the real experience: bathing in natural thermal waters that rise up from the ground just like they did 2,000 years ago.

The vibe here is different from most UK cities. Everything feels a bit softer, a bit slower. Georgian architecture lines the streets, and cafés spill out onto cobbled corners. The spa itself blends that historic charm with something refreshingly modern: rooftop pools, steam rooms, and saunas, all fed by the same mineral-rich spring water the Romans once swore by.

If you can, book a weekday slot - it gets busy on weekends and holidays. The rooftop pool is the highlight, especially at golden hour when the city glows and you’re floating in warm water, high above the street noise.

What to do after your soak:
– Wander to the Royal Crescent for a dose of history and some quiet park time.
– Browse one of Bath’s indie bookshops or cozy cafés: Society Café or Good Day Café are favorites.
– Or just walk slowly and admire the stonework - it really is that pretty.

And if you’re making a full weekend of it, there are some beautiful guesthouses and boutique hotels tucked into the Georgian townhouses near the city center.

How to get there:
Hop on a direct train from London Paddington to Bath Spa - it takes just 1.5 hours. The station is right in the heart of town, and you can walk to pretty much everything from there, including the spa.

Szechenyi Baths, Hungary

Located in the heart of Budapest, the Szechenyi Baths are the largest thermal If you’ve been curious about thermal baths in Europe, Szechenyi in Budapest is one of the most iconic places to start. This massive spa complex was built in the early 1900s and still feels like stepping into another era - just with a lot more steam.

It’s not a hidden spot by any means, but there’s something undeniably charming about soaking in warm mineral water while surrounded by baroque architecture. Temperatures range from 21°C to 38°C, and you’ll find both indoor and outdoor pools, so there’s always a spot that feels just right. The outdoor ones are especially lovely in cooler months: you’re floating in steaming water while the air is crisp and cool.

Heads up: It can get busy, especially on weekends or in peak travel seasons. But if you're okay with a bit of company and want that classic grand bathhouse experience, this one delivers. And the people-watching? Surprisingly entertaining.

If you’re looking to make a day of it, grab a cabin (for privacy), try one of their traditional Hungarian treatments, or just hop between the pools at your own pace. The atmosphere is laid-back, even with the crowds.

Don’t miss:
– Soaking under the stars if you're visiting in the evening.
– Walking through City Park afterward—it’s right next door and offers a quieter space to wind down.
– Trying a chimney cake from a nearby stand. It’s not exactly wellness, but it’s part of the experience.

How to get there:
Take Budapest Metro Line 1 (the yellow line) to Széchenyi fürdő station - it drops you right outside the entrance. You can also get there by tram or a short taxi ride from most places in central Budapest.

Autumn and winter offer fewer crowds and the magic of warm water in cold air.
Spring is ideal for pairing thermal baths with blooming landscapes and lighter crowds.

What should I pack for visiting European hot springs?

To enjoy your soak without stress, pack:

A swimsuit you don’t mind getting mineral-stained (especially in sulfur-rich springs).
A dark-colored towel (lighter ones can hold the sulfur smell).
Water shoes or flip-flops – especially in natural pools with rocky floors.
A dry bag or waterproof pouch for your belongings.
A reusable water bottle – thermal water is dehydrating!

Some spas offer rentals, but many rustic springs don’t - so packing your own is always smart.

Do you need to book hot springs in advance?

It depends on the location. Here’s a quick breakdown:

Are European thermal baths suitable for solo travelers?

They're often safe, welcoming, and full of locals who are there to relax (not to socialize. Bring a book, your journal, or just yourself) it’s the kind of travel that fills you up quietly.
