About Forbidden Forest

Founded in 2016, Forbidden Forest is a magical place where people celebrate their love of music, nature and dance.

Its stunning home, Belvoir Castle (meaning 'beautiful view') is located in hundreds of acres of lush forest, surrounded by rolling hills as far as the eye can see and steeped in history dating back to 1067.

Expect the best of the best talent across House, Tech House, Techno and D’n’B, with a lineup of over 50 outstanding artists, providing a stand-out soundtrack for a forest rave like you’ve never experienced before.

Together with its Forbidden Family, this festival has created an environment where all are equal and all are united by the love of electronic music.
