quiet sessions

Take part in a truly personal adventure where calm meets challenge! Our exclusive Quiet Sessions are specially created for individuals with Special Educational Needs (SEN), offering a welcoming, safe and sensory-considerate environment for everyone to enjoy.

Quiet sessions

  • Approx. 2hours
  • Age 6+

Find your calm among the treetops. We’ve turned down the volume and turned up the peace – no background music, no distractions – just the sounds of nature and the space to move at your own pace through our high ropes course.

Our team understands that everyone experiences adventure differently, which is why our Quiet Sessions are designed with SEN participants in mind every step of the way.

From gentle encouragement to patient, trained instructors, we create an atmosphere where confidence can grow and achievements are celebrated – no matter how big or small.

It’s all about making adventure accessible, enjoyable, and empowering for everyone.

FAQ's

What should I wear?
Wear closed toe, flat, sturdy shoes, trainers are ideal. Remove all jewellery. Glasses will need to be held on with a retainer, if you don’t have one you can borrow one for a returnable deposit. Thin layers (t-shirt, long sleeve top, fleece etc) are best – you can aways take a layer off or add another. Bring a waterproof with you. Although some of our courses are amongst the trees there’s lots in the open air too. You’ll get warmer as you take on our aerial ropes, obstacles & challenges.
