Beach Bonkers will be bringing a tableful of beach treasures, a portable beach and a giant beachcombing board game to National Trust Dunwich Heath & Beach.
They will also be offering other nature activities and you can even do a mini beach clean and get a free tea or coffee.
All activities are free although donations are welcome. There is a charge for car parking.
If the day inspires you to find your own beachcombing treasures then come and find your own on a Beach Bonkers beachcomb.
