Picture this: you're soaking in a thermal pool in the Dutch countryside, and beneath your feet lies the ghost of a working zoo. That's the curious reality at Thermae 2000, the Netherlands' oldest and largest spa resort, which opened in 1989 on the grounds of what used to be a thriving menagerie complete with elephants, lions, and other creatures.
The transformation was dramatic. Zookeepers gave way to masseuses. Training grounds became treatment rooms. Where elephants once walked, guests now drift between infrared saunas and massage chairs. One artifact from that wild past remains: a mammoth tree so massive and protected by law that the entire spa complex was built around it. Today it stands as an unlikely monument to both nature and reinvention, towering over state-of-the-art wellness facilities.
A pyramid on Holland's most famous hill
The resort sits on the Cauberg, essentially Holland's most celebrated small mountain, just outside the charming town of Valkenburg in the country's southern reaches. The building itself is striking: a pyramid-shaped structure that cuts an unmistakable silhouette against the countryside. Being only 90 minutes from Brussels makes it an easy escape for anyone seeking a restorative long weekend.
Two Dutch physiotherapists, Marcel Jaspars and Mijndert Verschuur, founded the place, which explains why it feels so thoughtfully designed for actual recovery. Their naming choice was clever: they took the first letters of their first names (M and M) and converted them into Roman numerals. Thermae 2000 was born. The pair eventually parted ways but reunited years later to celebrate the resort's 30th anniversary with staff.
A sauna lover's paradise
The wellness offerings here are genuinely hard to overstate. The resort boasts what may be the largest collection of saunas under one roof in the entire country. You could theoretically spend seven days trying a different one each day and still have several untried. The crown jewel is Infinitum, a massive sauna with floor-to-ceiling windows and sweeping views of unspoilt countryside that make you feel miles from civilization despite being a short drive from town.
Beyond saunas, the spa menu reads like a luxury wellness encyclopedia. The Lomi Lomi massage mimics the therapeutic rhythm of Hawaiian waves rolling onto shore; guests get slathered in fragrant oil and worked over for 50 minutes. The Lotus massage targets front, back, and face in another 50-minute session. The newest offering is a Japanese head spa treatment available in both a 45-minute deep-cleanse version (89.95 euros) and a more lavish 75-minute experience (114.95 euros) that extends to the neck, face, and back.
Patricia, a masseuse who's been here over 30 years, has perfected these treatments alongside her husband, who also works in the facility. Their kind of loyalty is baked into the place's DNA.
Stay longer than you planned
Day visitors often find themselves so enchanted that they book a room. The resort has 74 guest rooms including 14 wellness suites. The newest suites opened recently in converted office space and feature private infrared saunas, countryside views, and access to recently renovated gardens. All rooms connect directly to the wellness center, so you can wander in a bathrobe from breakfast to sunset. Fair warning: the resort designates certain swimwear-only and clothing-optional days, so check ahead.
Patty, who joined the wellness staff five years after opening and has been here ever since, carries her own thread to the site's strange history. Her uncle actually lived at the zoo and worked as a lion tamer. She bridges the two eras, remembering the menagerie while helping guests find peace in the saunas.
For those curious about how the Dutch approach relaxation and slowing down, Thermae 2000 is a masterclass. The restaurants, including Bread & Bites overlooking the pool, serve hearty Dutch fare without fuss (dining in a bathrobe is not only tolerated but encouraged). Staff friendliness creates a warmth that lingers long after you leave.
This isn't a luxury resort pretending to care about wellness. It's a wellness operation that happens to have excellent rooms and food. Built by physical therapists who understood that bodies need attention, it stands on soil that once held wild animals, now channeling that untamed energy into healing. The mammoth tree overhead seems to approve.
