The Netherlands is a land defined by its relationship with water, though usually, that water is something to be held back by dikes or navigated by boat. The Netherlands has few natural, geothermally heated hot springs, but it boasts excellent thermal spa resorts using deep-ground mineral water.

For the hot spring enthusiast, the Dutch landscape—flat, sedimentary, and geologically stable—doesn't immediately scream "geothermal activity." You won't find the bubbling mud pots of Iceland or the steaming volcanic vents of Japan here.

Near Amsterdam, "taking the waters" is an art form, blending historical UNESCO sites, modern architectural marvels, and mineral-rich thermal brine.

In the Netherlands, the default state for a wellness resort is nude and mixed-gender. In most of the spas listed above (except on specific "Swimwear Days"), wearing a bathing suit is actually forbidden for hygiene and health reasons.

If you are shy, look for Badpakkendag (Swimwear Day) on the spa’s calendar. Almost every spa has one or two days a week where suits are mandatory.

While you soak naked, you never sit directly on the wood of a sauna or the stone of a bench with your skin. You must bring a large towel (or two) to sit/lay on.

Dutch spas have incredible restaurants. It is perfectly acceptable—and quite common—to interrupt your thermal journey for a robe-clad lunch of Bitterballen (deep-fried meat snacks) and a fresh mint tea.

Don't miss the Opgieting rituals. A "sauna master" pours water and essential oils over hot stones and uses a towel to swirl the scented steam around the room. It is a sensory experience that turns a simple soak into a theatrical event.

1. Fort Beemster

Located just 20 minutes north of Amsterdam in a UNESCO World Heritage site, Fort Beemster is perhaps the most unique spa in the country. Set in a former military fort this upscale spa hotel surrounded by a moat is 3 km from the Purmerends Museum and 14 km from tours of De Kat windmill.

This former military fortress, part of the Defense Line of Amsterdam, has been transformed into an eco-chic wellness retreat. Its water is drawn from a private well, rich in minerals from the Beemster soil.

A stay at Fort Beemster means you get luxurious rooms and suites beautiful views over the Fortgracht. The Poterne Restaurant is the best kept secret of the Beemste and is recommended by Michelin. The Poterne restaurant is adjacent to the Poterne terrace, surrounded by high grass dikes, lounge sofas, fireplace and lounge tent with bar and kitchen.

In the wellness resort you will find unique saunas, including a botanical sauna, kelosauna, and panoramic sauna. Several outdoor and indoor pools, herbal bath, salt water pool and a spa with various relaxing massages, facial treatments and hammam.

It’s a nude sauna on most days (except on bathing suit days) but then (almost) every Dutch sauna is.

Quiet zones were limited. There was only one indoor relaxation room, and the beds were arranged closely together, making it hard to find a peaceful corner.

Ease of Access: ★★★★☆ – A quick drive or a direct bus from Amsterdam North.

2. Spa Zuiver

For those who don't want to leave the city limits, Spa Zuiver is the undisputed king of urban wellness. Located at the edge of the Amsterdamse Bos (the city forest), it feels miles away from the bustling canals.

You can enjoy one of many spa pools both inside and in the garden. They let you add mint or eucalyptus to your own bath for some aroma healing.

If you love a cold plunge after the spa, this place is for you. Experience the feeling of cold raindrops on your warm skin under the meter-high cold waterfall. When the plunge pool or a cold shower is just a little too much for you, this waterfall of 14 °C offers a solution.

The property has arranged Tuesday, Wednesday and Thursday as swimwear day and wearing swimwear is mandatory. On all other days, it is not permitted to wear swimwear.

Though located in the south of the country, it is the "spiritual home" of Dutch hot springs. Many Amsterdam locals make the 2.5-hour pilgrimage here specifically for the water, which is drawn from three deep wells on the Cauberg hill.

Perched atop the famous Cauberg hill, Thermae 2000 is the undisputed king of Dutch thermal baths. Its water is tapped from three ancient subterranean springs—the Ursula, Amalia, and Beatrix—which have been filtered by marl layers for over 40,000 years.

5. Carolus Thermen

Wait, Germany? Yes. Because Amsterdam is so well-connected, many enthusiasts take the high-speed train to Aachen (2.5 hours).

This is a legitimate ancient Roman hot spring site and offers a level of geothermal heat that the Netherlands cannot physically produce.

With a daily yield of 3.5 million liters, the more than 30 sulfurous Aachen and Burtscheid mineral thermal springs are among the most productive mineral thermal springs in Germany. One of these springs is the Aachen Rose Spring. From this spring, the Carolus Thermen continuously receive fresh mineral thermal water of the best quality via a pipeline.

Hot, sulphurous water bubbles up from more than 30 underground thermal springs in Aachen, the healing and regenerative effects of which have been known since ancient times.

Aachen’s hot springs have been known for more than 2,000 years and are still inseparably linked to the history – and the name – of the city. For the city name Aachen can be derived both from the Old High German word “ahha” (water) and from the early medieval “Aquis grani” as well as the Latin “Aquae granni” derived from it, which in turn refers back to the Celtic god of healing Grannus.

After the Celts and Germanic tribes, it was above all the Romans who discovered the healing and soothing effects of the Aachen springs and celebrated a comprehensive bathing culture in spacious, luxurious thermal baths.

The swimming area is like a water park for grown ups. There are eight indoor and outdoor pools of various temperatures, the unique brine steam bath “Strokkur”, a beautiful sun terrace and even a beach. The main pool connects with several others and includes amenities like bubbles, waterfalls, and gentle currents. I also noticed a lift for disabled visitors.

If you have a family, they only allow children over 6 and kids under 15 need to be accompanied. For 2026 the proces for the thermal baths range from 19 to 25 euros depending on the day and number of hours. Parking is 6 euros per day.

Bring your own towel and robe or rent them. You can get a towel for 2 euros or robe for 8 euros.

The sun terrace is a lovely outdoor area surrounding one of the two outdoor pools on this level. There’s a little faux beach with sand and beach chairs, as well as a small bar/cafe where you can get refreshments.

While the thermal bath area requires swimwear, the saunas are bare skin. People don’t just walk around naked the whole time (although they could), but wraps or robes are hung on hooks outside each room, and you just use a towel between you and the seat as a cushion and heat barrier, and to keep your sweat off the wood, because you will sweat.

There is a Feminarium for women who want to sauna nude without any male observers.

Downstairs from the dry saunas is a pool surrounded by steam rooms. These are higher humidity and had a wide range of temperatures. I enjoyed the Tepidarium, which, at 27°C, was just warm enough to feel it without trying to kill me, but my favorite was the Odorium. The Odorium is named for its aromas which were truly heavenly.

If you are like me and miss the ocean, try the Oceanarium for only 4 euros! Enjoy a day on the beach in a 40-minute animation. With the sound of the ocean and relaxing music, you will experience a decelerating beach atmosphere – from sunrise to sunset. The brine sprayed into the comfortably furnished relaxation room in Nordic design not only creates a pleasant salty sea climate, but is also good for your respiratory system and bronchial tubes.

Water Quality: ★★★★★ – World-class. The mineral water from the "Rosenquelle" spring is legendary.
Ease of Access: ★★★☆☆ – An international trip, but very doable as a long day-trip or weekend.

Thermen Bad Nieuweschans has rooms with a private bathroom and either a terrace or balcony. Guests can enjoy breakfast buffet in the morning.

For an additional charge, guests can make use of a hammam and Turkish steam bath treatments. There is also a spa bath.

Many saunas to choose from, 3 hot baths outside. I especially liked that you could swim from indoors to the outside part of the pool. At the edge of the bathrobe park, you will find the Park Pool. As you immerse yourself in wonderfully warm 36°C water, you can enjoy a beautiful view of the green park. The combination of the soothing saltwater and the endless view helps you completely unwind.

I love that the outdoor pool is infused with magnesium, which has a calming and relaxing effect - think epsom baths!

The ice pool is tiny! It only can effectively fit 3 people in it.

You need to bring a bathrobe if you want to go to any of the restuarants here (big towel does not count). All days except Wednesday you have to be nude in the spa.

It focuses on the "nature" aspect of wellness. Start out with the foot bath to start wraming up.

I love the hammam bath. A golden combination, and the recipe for ultimate relaxation. In this herbal bath, with a pleasant water temperature of 37°C, you can fully unwind and return to yourself.

Enjoy the bubbling whirlpool baths where you are surrounded by trees, the forest garden, and singing birds, it is pure enjoyment.

After warmth comes cooling. In the plunge pool, a refreshing cold-water bath of about 5°C, you cool your body down after your sauna session.

The Maarsseveense Plassen form a unique recreational area with beautiful beaches. From Thermen Maarssen, you look directly out over the shimmering water of the large lake. It is a special place where tranquility, nature, and wellness come together—ideal for fully unwinding or cooling off after a sauna session.

Hotel Thermen Bussloo - Apeldoorn consists of a hotel and a wellness center, which are connected by an underground tunnel - perfect so you don’t freeze after your spa day.

Cenote and grotto are amazing, they look very natural! They are built after the real cenotes in Mexico! The highlight of this place is most definitely the Cenotes themed bath, with salty water. I have never ever experienced this much floaty-ness in the salt water bath.

Hamam was also very good. This is right next to the cold plunge so it’s nice to switch between them.

We liked to have delicious tea with sweets afterwards.

Note that this is mostly a nude spa, so be aware. Every second and last Tuesday of the month is Swimwear Day at Thermen Bussloo. Wearing swimwear is mandatory all day on these dates.
