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.

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.

A great afternoon and evening was had by all of our party; something for everyone !
Seemed to be a mix of adult, children and family/ groups, therefore, a nice balance. We were with some friends and their children who had a session on the ropes/ Zip wires etc. Also did some air gun shooting which was a new experience for most of the group and was thoroughly enjoyed. There was a warm welcome here and the staff seemed to be enthusiastic and safety conscious. A lovely setting next the the secret nuclear bunker and the experience exceeded expectations. We will be back; our friends will be re visiting too – I’m sure.

Awesome experience loved the high ropes, zip trek and angel knife throwing… the drop is a must do!

The Nuclear Bunker was eye-opening and really interesting- and so secret that we almost walked past it!
Both students and staff had the most brilliant day at Wild Forest. This is our 5th year of bringing our new Year 12 cohort as a team building and bonding away day and it absolutely delivers on all counts. The staff are fantastic and the opportunities available to the students to push themselves to their muddiest limits both personally and working alongside their peers is brilliant to see!
High Ropes pushed our students to their highest limits- literally! Focus and determination was needed to navigate through the different levels.
