Brilliant activity (high ropes) for my son and his friends for his birthday. Cody and Tim were both lovely. The course is really good with 3 different levels and lots of time to go round. It’s also quite much cooler in amongst the trees during the heat! We’ll be back.

What a fabulous day! It went without a hitch and everyone had an incredible time! You and the team were amazing, your support and organisation all the way through has been top notch, from an events perspective I have not had to worry about a thing, you are a powerhouse lady! You take everything in your stride and you are on top of everything, it really has been a pleasure working with you on this, from start to finish! I think we are at about £3,400 total fundraising which is fab!

A bonzer big up to Sam (and the team) at Nuclear Wild Forest for being the hostess with the mostest and making it a morning to truly remember!
Our 50 strong team of muddy ducks ran, swam, climbed, clambered, rolled, pulled, slid, bounced and welly wangled their way around the Wild Forest obstacles and raised lots of lovely lolly for our chosen charity, the awesome, Aoifé’s Bubbles!
We can totally recommend the whole experience – it was the best fun, we literally belly laughed our way round the course and have already planned our return visit!
