Nuclear Wild Forest Outdoor Activity Centre

Parsonage Farm, Ongar Road Brentwood, Essex, Essex, CM15 0LA

Nuclear Wild Forest is a unique outdoor obstacle and activity centre located in Brentwood that offers muddy fun for all!

From muddy birthday parties (one that will be talked about for weeks) and Learning Outside the Classroom (LoTC) school trips; to corporate team building days and hen or stag dos; Nuclear Wild Forest has obstacles and activities to suit all ages.

What’s more, a visit can include more than just their obstacle course: axe and knife throwing can be thrown in the mix too! Plus, there’s their brilliant Lake Zone including Nuclear’s epic Deathslide (for children 10+ years).

Nuclear Wild Forest is also ideal for team building events or charity fundraisers, with obstacles challenging enough to encourage teamwork, alongside lots of fun and laughter.
