Fun downloadable ‘spy missions’ are being offered in Falmouth.

Treasure Trails invite people to take part in a two-hour walk solving clues to thwart a crazy scientist trying to take down the Falmouth Oyster Festival.

The trails are suitable for children above the age of six and groups of up to five.

The aim is to use Falmouth landmarks, plaques, signs, statues, monuments, images and engravings to solve the puzzle.

If you get stuck, there is a text message help service.

Trails cost £6.99 and can be purchased at

They are also available in 62 other locations in Cornwall including Tingtagel, Padstow, Newquay and Bodmin Moor.
