Crate stacking at Calvert Devon
What is a crate stack?
As a team, the goal is to stack plastic crates as high as they can in a tower.
The catch? Two people are standing on top of the tower while building it. They’re tied into a belay system that ensures they’re caught safely should the tower fall, but they’ll need to use their problem-solving and communication skills to keep the tower steady and build it as tall as they can. They’ll also need help from those around them, who pass crates, manage the rope systems and offer lots of encouragement.
This can be repeated in twos to see which pair can have the most crates stacked before they fall or the tower topples down.
At Calvert Devon, we adapt the activity and provide support with specialised equipment to ensure everyone can enjoy crate stacking, regardless of age or disability. This could include the use of slings and hoists and even pairing participants in a way that promotes and develops their skills best.
With both an indoor and outdoor crate stacking area, our trained and qualified instructors can run sessions come rain or shine.

Yes! We leave no one out, and no matter what, we do everything we can to ensure that you can enjoy the crate experience in a way that suits you and keeps you safe.
The Calvert Devon instructors use the term ‘challenge by choice’, which ensures that while you’re taking part and given challenges along the way, you ultimately always have the agency and control over your own limitations.
Our staff are there to keep you safe but also build your confidence, even if this means accomplishing a simpler version of the activity.
There are two crate stack areas.
The first is in our sports hall at the heart of the centre.
The second and newer area is outside, at the bottom of our main carpark, looking out over the reservoir.
Every instructor has extensive in-house training, including observation hours logged before running a session independently.
Every instructor also has specific qualifications:
- Either
- a Climbing Wall Instructor (CWI) qualification, including an abseil module by the British Mountaineering Council
- OR
- a Rock Climbing Instructor (RCI) qualification by the British Mountaineering Council
Both of these qualifications are transferable to crate stacking.
Established and essential governing bodies monitor instructors and the centre, such as the Association of Heads of Outdoor Education Centres (AHOEC) and the Activity Activities Licensing Authority (AALA).
