SENSAS in complete darkness: what to expect before you go

It's often the first question people ask before booking: "what if I panic in the dark?" A fair one. But SENSAS isn't a solo trial where you're left to fend for yourself in the darkness: it's a collective trail, with challenges that test each of your senses, designed to be experienced together.

Never alone in the dark

The idea behind SENSAS is to step out of your visual comfort zone — not out of the group. The entire part of the trail that takes place in complete darkness is done as a team: you guide each other, communicate, and move forward together from one sensory challenge to the next. It's precisely this interdependence that makes the experience worthwhile — you rely on your other senses and on the other participants, never on yourself alone against the dark.

In practice, these are challenges that test each of your senses: deprived of visual cues, you compensate with hearing, touch, spatial orientation — and above all with each other. Roles naturally emerge: one person describes what they're touching, another guides the walk, another keeps track of the challenge. That's what makes the fear of the dark largely overblown once the first challenge starts: attention shifts to the group and to solving the task, not to the darkness itself.

This group logic is the same one found in a team building event in Geneva: formats that force people to coordinate under constraint, which is exactly what creates shared memories and cohesion.

Accessibility: what's in place

SENSAS is accessible to everyone, including people who get around on crutches or pregnant women. The trail can be adapted accordingly: just mention it when booking so the team can prepare the version suited to everyone's needs. In other words, a mobility constraint shouldn't stop you from coming: just let us know in advance.

The reflex to have: mention any special need — crutches, pregnancy, or any other constraint, including any apprehension about complete darkness or confined spaces — when booking rather than on the day itself. That gives the team time to prepare the trail and welcome you under the best conditions, with no last-minute improvisation.

On the logistics side: there's no dedicated parking on site; Parking Butini and Parking de l'Hôtel Wilson are the closest options.

Who SENSAS is for

The format is deliberately broad: it wasn't designed as a trial reserved for regulars of immersive experiences, but as an outing that can be suggested to pretty much any group — family, friends, colleagues — without pre-sorting who can "handle" the dark or not. Here are the key facts to know before booking.

• From age 7 — the activity suits families as well as adult groups.
• From 4 to 36 people — flexible enough for an outing with friends as well as for a larger group.
• 1 hr 45 min duration — enough time to go through all the sensory challenges, as a team.
• On request — any mobility constraint should be mentioned when booking, for an adapted trail.
