There are two sessions from 11-1 and 2-4 with the library closing for lunch from 1-2.
Can you decipher the clues to find the treasures hidden in the mini-beach?
There will also be a tableful of beachcombing treasures for you to handle. Have you ever seen a mammoth's tooth?!
And a giant beachcombing board game - will you look after the beach and make it to the end and become a successful beachcomber?
Then you'll be inspired to come and find your own treasures on a Beach Bonkers beachcomb.
This is a free event thanks to a grant from the Suffolk Secrets AONB fund.
