Sometimes the best vacation doesn't require a plane ticket. While Southern Europe's summer surge continues to dominate travel plans, smart travelers are discovering that a few kilometers from Brussels lies something equally restorative: thermal spas where you can actually afford to show up multiple times.
Starting June 15, 2026, Thermae is rolling out a five-visit summer pass at both Boetfort and Grimbergen locations. If you've been meaning to get serious about that whole "local wellness retreat" thing, this promotion might finally make it happen.
The Deal That Makes Sense
Here's the math: at Thermae Boetfort, the five-visit pass costs €169, which breaks down to €33.80 per visit. Without the pass, you'd spend €204.50 to €229.50 for five separate days, saving you up to 26% by buying in bulk. Over at Thermae Grimbergen, the pass runs €142 (€28.40 per entry) versus the regular €179.50 to €194.50 you'd pay otherwise.
Beyond the entry savings, both passes unlock a 10% discount on massages, facials, and body treatments. The whole promotion runs through September 18, 2026, so there's a genuine window to use it, but not an infinite one. The passes aren't tied to your name either, meaning friends or family members can share them if you're not using all five visits yourself.
Boetfort's Ancient Park Meets Modern Wellness
Thermae Boetfort sits within a centuries-old park just outside Brussels, and the outdoor summer experience is where this place really shines. You get multiple saunas and steam baths indoors, but come July, most visitors gravitate toward the exterior pool, scattered jacuzzis, and acres of lounge chairs where doing absolutely nothing is considered peak relaxation.
The Boetfort pass is sold exclusively at the reception desk for €169, and it's the kind of investment that pays dividends if you actually commit to multiple visits. A quick afternoon dip. A full day of sunbathing. A friend date that turns into four hours by the water. Across five visits, those moments add up.
Grimbergen's Lakeside Escape
Thermae Grimbergen brings its own flavor to the equation. Inside, you'll find saunas ranging from a gentle 55°C to an intense 85°C, plus the kind of Roman steam bath that makes you understand why people have loved thermal baths for thousands of years. Outside, it's all natural swimming pools, plunge baths, jacuzzis, and a genuine natural lake where you can float and watch the sky change colors.
There's a cocktail bar too, because why sweat it out and then deny yourself a decent drink? The Grimbergen pass costs €142 and offers the same flexibility as Boetfort's version. Buy it at the reception, use it however works for your schedule, and bring whoever you want.
Why This Matters Now
Staycations have momentum for good reason. You get genuine recovery time without the logistics nightmare of international travel, airport queues, or jet lag. Both Thermae locations sit just a stone's throw from Brussels, making them practical for weekday escapes or weekend resets.
If you live in the region or plan to spend time in Belgium this summer, this pass removes one of the biggest friction points: the cost. Instead of deciding whether you can afford another spa day, you've already committed to five, and suddenly it feels like something you actually do rather than something you think about.
The promotion runs through mid-September, so you've got roughly three months to squeeze in five visits. That's either luxury or pressure depending on how you look at it. Either way, it's hard to argue with the economics.
