The bubble is the most photographed stay in the category and one of the hardest to get right. The principle is simple: an inflatable sphere held under pressure by a silent blower, a bed at the centre, and a 360° view of the canopy and the sky. What separates a great bubble from a bad night comes down to three details: the location (far from light pollution), the ventilation (without which condensation ruins the transparency) and privacy (an opaque section is essential).
Belgium is compact, and that is its strength: two hours from Brussels and you are deep in an Ardennes valley, without having taken a plane. Supply has concentrated in the Ardennes, the Famenne and the Kempen.

Three things the directories will not tell you, and that separate a good night from a bad one.
Hunt for light pollution. A bubble three kilometres from a lit retail park will show you no stars at all: always ask for a photo of the night sky taken on site.
The blower runs all night. It is silent in the good bubbles and audible in the bad ones — that is the first thing to look for in the reviews.
In summer a bubble can become a greenhouse. Check it is shaded during the day and properly ventilated; in winter, check the heating.

Frequently asked questions
Can you really see the stars from a bubble?
It depends entirely on the location. Under a dark sky the experience is stunning: the Milky Way is visible from the bed. Near a town or a streetlight you will see almost nothing. This is criterion number one, ahead of comfort and ahead of price.
Is there any privacy in a transparent bubble?
Serious bubbles include an opaque section — usually the bed area plus an airlock leading to a separate bathroom. Fully transparent bubbles exist, but they require a completely isolated site.
Can you get there without a car?
More easily than in France: the Belgian rail network is one of the densest in Europe. Several Ardennes hosts offer transfers from Marloie, Jemelle or Libramont stations.
