Add in the neighbouring Nuclear Wild Forest Activity Centre, and you’ll find adventures at ground level, high in the trees, and underground.

Nuclear High Ropes Brentwood is more than just a ropes course. It’s an entire outdoor learning experience set on 1,600 acres of woods and farmland on the edge of London in Brentwood, Essex.
