Things to do

A Treasure Trail is a fun way to explore on a self-guided route, solving the sneaky clues set along the way.

Will you discover whodunnit on a detective mystery, reveal the location of the lost loot on a treasure hunt or crack the code on a spy mission? With over 1,200 Trails across the UK, you'll be spoilt for choice.

The Hertford detective mystery Trail begins in the free car park adjacent to the beautiful Hartham Common. You'll hunt high and low for captivating clues, exploring along the peaceful river towpath, through the ancient castle grounds, and down the historic streets of Hertford town.

All you need to set off on your self-guided adventure is a Treasure Trails booklet, which costs just £9.99 (plus p&p if required), and one booklet is all you need for up to five people! Pick up your Trail booklet from the Treasure Trails website.
