Forty people will be stepping off the top of the tower of the Maritime Museum in Falmouth on Saturday, all in fancy dress and all aiming to raise as much cash as possible for Tanya’s Courage Trust.

King Kong, the Queen and bank robbers will be among the characters taking the plunge with the help of professional abseil instructors from BF Adventure between 10am and 3pm.

Organisers are hoping crowds of spectators will turn out on the day to support and cheer on those taking part.
