Closed until further notice

Will you dare to take the step?

Book the coolest adrenaline challenge at Vaxholms Kastell, Walk the plank.
95 stairs up in the tower, the pulse is increasing, adrenaline pumping, legs shaking and your forehead is damp from sweat! Will you dare to take the step over the edge and drop 18 meters down and land in the gravel on the fortress courtyard?

The experience as a whole

The activity guide will secure you in the Quick Jump module. You will then step up into the window and balance out on to the plank. The plank sticks out from the top window in the tower and is somewhat tilted downwards .

At the end of the plank you will stop and take a deep breath. After that you will decide yourself when to take the step out and fall down towards the ground. The safety device will break the drop softly before you land on your feet on the fortress courtyard.

Q & A


Is there any jerk in the fall?

There is no jerk; the drop starts with a free-fall followed by a soft landing.

Can I fall in to the tower?

No, no matter how windy or if your jump is askew you can not fall in to the tower.

Who built Walk the plank?

The assembly has been done according to EU-regulations for rope and climbing facilities: EN-NS-15567-1 by experts from Hoyt o Lauvt in Norway.

What is the Quick Jump module?

The Quick Jump Free Fall module contains an advanced, self-regulating break system. The patented break mechanism offers the jumper an initial free-fall followed by a controlled landing. Regardless if you weigh 30 or 120 kg you will drop to the ground at the same speed after you have stepped out into the air.

Can you combine Walk the plank with any of your other activities?

Of course! Book Walk the plank for example after finishing “Fångarna på Kastellet” (“Prisoners at the Fortress”), either for just a few of you, or the whole group. Walk the plank is the perfect challenge for the bride/groom at the bachelorette/bachelor party. Or why not challenge the boss?
