The camp has been set up by the National Crime Agency (NCA).
The idea is to divert potential cyber-criminals into useful cyber-security work.
The first seven attendees are people caught engaging in cyber-crimes like defacing websites, taking servers offline and hack attacks.
At the Bristol centre learnt about forensic analysis, network protection and hack attacks on companies.
They did coding challenges, engaged in hacking games and learned about bug bounty schemes where you get paid for finding bugs.
