The events were really well organised and very enjoyable (and tiring) to take part in; and the training days were really helpful in getting to practice some of the stations and get some race like preparation done. I will definitely be back for both the training days and the events in 2027.

This is now the sixth year that I have been bringing our Year 7s to the Nuclear Wild Forest and there is a reason why we keep coming back! The staff are amazing with all our students and encourage them to do the activities especially when they feel apprehensive. Safety is always a high priority, ensuring students feel safe while doing the activities. All our students had a fantastic day and are already asking if they can go back. Thank you Sam and her team.

Bringing Music Mudder to a new venue was a significant step for us, and your support, experience and commitment throughout the planning and delivery gave us real confidence. From the preparation behind the scenes to the welcome and support on the day, the Wild Forest team played an essential part in bringing the event to life.

Around 400 people from teams across the music industry took part, supported by approximately 200 colleagues from across our organisation who participated or volunteered. We have already raised more than £54,000 for Nordoff & Robbins, and we expect the final total to be close to £60,000 once the remaining fundraising and raffle proceeds have come in.

The feedback has been fantastic. People loved the course, the setting and the atmosphere, and we have heard repeatedly what a brilliant experience it was for both team building and supporting such an important cause.

I also know that an event of this scale creates plenty of challenges and moving parts behind the scenes. The flexibility, practical support and positive approach shown by you and your team made a huge difference, and I am extremely grateful for the way you worked alongside us at every stage.

Music Mudder has now raised more than £350,000 for Nordoff & Robbins since 2019, and this year has given us a brilliant platform to build from. We are already excited about what we might achieve together in 2027.

The Team – Music Mudder

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.

DC22

Loved it. Tim and the team were all great. High ropes courses super, lovely setting. Not over packed and felt we could take time. We also did the zip wire course which is fantastic and quite frankly amazing value for what you get. A really fun family afternoon in a forest, over water with ultra safe facility and kind, fun people. As a shout out I would say it’s the first time someone helpfully coached me on some tricky bits. Special.

We would like to sincerely thank you for the incredible experience you provided for us and our students during our visit on 27th July 2026.
The day far exceeded our expectations. From the moment we arrived, the energy, enthusiasm, and professionalism of your team created an unforgettable atmosphere. The liveliness and engagement of your staff, particularly Tracy and Will, truly elevated the experience for our students. Their ability to connect with the boys, motivate them, and bring out their potential was remarkable.
We especially appreciated the care, attention, and focus given to our group throughout the day. It was clear that every student was valued, encouraged, and supported, which made a lasting impact on them. The boys returned not only thrilled, but genuinely grateful for the warmth and encouragement they received.
As an educational, non-profit institute with approximately 350 students, we are always seeking meaningful and enriching experiences for our pupils. Your programme has certainly earned a place at the top of our wish list, and we would love to make this a regular visit, particularly for our Year 8 and Year 9 groups.
Once again, thank you for your outstanding hospitality and for delivering such a memorable and inspiring day.

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!

Took our football teams along for our end of season event. The players all absolutely loved it and have asked to go again for pre season training – Sam and her team were so supportive and encouraging of the team and helped and pushed them to try all of the amazing obstacles. The Death slide is EPIC!

Neil Brooks – Stanway Rovers YFC

Tracey and Helen were excellent & really encouraged the scouts to try to the best of their abilities. They had a superb evening and we will definitely be back!

Oliver Dellow

Residential Finisher
We visit Nuclear Adventures every year, as part of our residential, and always have a really fun time! The staff are friendly and efficient and help the children feel comfortable on the ropes, even rescuing us when we get stuck!
‘I really liked it, especially the zipline!’
‘I did feel like I was going to fall off but I never did, my harness held me in safe and I made it around the course!’
‘It was really fun, the level two course had cool elements to step across.’
‘I liked level two and the parts of the course that changed every time, it was a new challenge!’

Emma – Sacred Heart School

After a literal decade of arranging kids parties, Nuclear Wild Forest is THE best parties for boys AND girls! The assault course is a proper assault course and throughly fun and enjoyable. The instructors are so experienced and great with the kids, and lovely with them. Sam, the Manager, might just be the most efficient and helpful manager whom I have ever come across. Such a brilliant day out. All you need is a change of clothes, shoes and towel for the end! Can’t speak highly enough of it.

Georgina Sharkey

Wow!!! Sam and the team have been amazing from start to finish. Their prompt responses to my enquiry, the great advice they offered prior to the party with my numerous questions and then the fun that they created on the day for my son’s 9th birthday was first class!! I can’t thank you all enough and would highly recommend you to others.

Hayley W

Thank you to you and the team for a seamless, incredible experience for the Gold Geese community. You run a slick operation! A great day was had by all.

3 Nuclear activities for the 5th Dartford Scouts

5th Dartford Scouts had an incredible weekend going Nuclear: Bunker visit, Mud Obstacles and High Ropes courses.
Excellent instructors making it fun for all our age ranges.
Thoroughly recommend, with plans to repeat the visit.

Paul Boreham

Big Drop was a highlight

Took a stag party here and had a fantastic time. The high ropes were brilliant and the 50 foot drop in a harness was something I never thought I’d be able to do, but it was epic. Great course with multiple difficulty/height levels and some decent zip lines too. 10/10 would recommend for a few hours of fun. 👍🏻

Ben – March 2026

Wonderful time doing knife throwing!

Wonderful time doing knife throwing! So laid back, really kind and friendly, and wonderfully down to earth. Perfect for a get together! Can’t wait to go back

The Best Birthday Ever!

The best birthday party ever! We had my son’s 8th birthday party at Wild Forest in January. The boys absolutely loved it! There were so many fun obstacles for all abilities. They also loved the fire pit at the end where they toasted marshmallows. I am sure we will see you again soon for one the boys birthday parties!

Mum – Rachael H

Our triathlon club kids had a fantastic time at the winter bobble hat run!  Thank you to Sam helping us to organise it and to the team for taking our club members out on the course, it was a perfect winter social event, the kids absolutely loved it & then toasting marshmallows at the fire pit, with hot chocolate & getting a Dominos delivery was a perfect ending!  Highly recommend!

Chelmsford Tri Club

We had a great time at the Nuclear Races event in Brentwood. The event was well organised with friendly staff, good quality food/ drink trucks and a fun course that catered for all ability levels. Would definitely recommend!

Tim Flack (Level Up Gym)

Went to Nuclear Races for a corporate day out last week and had a really great time! Definitely a good event for team building and getting to know people better. The Nuclear Races team were super friendly and also more than happy to laugh at our attempts to cross the various obstacles…
Would highly recommend.
