They are a really good and fun way to explore a new town or city, or your local area... Suitable for all ages. We are in our 70's.

We were a group of 3 generations between 17 and 70ish – you really don't need to have children with you to enjoy these trails.

We've got a mission for you in

District Line (Green Run)

Attention all Londoners and visitors alike! Our beloved city is under threat from an unlikely villain - failed English ski-jumper, Chas "the Budgie" Basiljet. He's devised a dastardly plan to flood the District line with stinky sewage, causing chaos and mayhem. But fear not, brave adventurers! The code to stop his evil traps is within reach, and with your help, we can save the day!

Spy Mission Along the District Line

Embark on an exciting self-guided spy mission through the heart of London, following the iconic District line from Tower Hill to Earl's Court. Along the way, you'll uncover sneaky clues hidden in plain sight on existing buildings, permanent features, and monuments. It's up to you to crack the code and foil Chas's foul mission, just like a true secret agent!

So grab your family and friends, hop on the District line, and get ready for a day of fun, adventure, and family-friendly excitement. But be quick - time is of the essence, and Chas is one slippery villain!

More Information:

Essential Intel

This is a linear tube-based mission from Tower Hill to Earl's Court, so Agents finish away from the start and will need to make their own way back if they want to return to Tower Hill.

Toilet access is confirmed at Cannon Street, Victoria and Earl's Court stations. At South Kensington, do not use the museum passage - Basiljet's sludge plot has made that route strictly off-mission.

Navigating The Route

This is a linear Spy Mission along the District line from Tower Hill to Earl's Court, with Agents helping stop disgraced ski-jumper Chas 'The Budgie' Basiljet after he rigs the line with traps and a murky sludge plot.

The operation should take around 4 hours to complete. You'll use tube stations and nearby streets, with clues kept within 50m of a station entrance, and investigate areas including Tower Hill, Cannon Street, Westminster, Victoria, South Kensington and Earl's Court.

This Trail is not suitable for wheelchairs or pushchairs. The route includes some steps, escalators and roads to cross, plus walking sections along the riverside and Victoria Embankment.

Mind the gap on the tube, use caution on escalators, and take care around roads, bridges and the riverside. At some points you can stay on the District line or walk instead, including walking from Cannon Street and following Victoria Embankment on foot to Westminster.

Getting There

By car: Begin the operation at Tower Hill Station (EC3N 4DJ). This is a linear mission ending at Earl's Court, so plan your return journey before you set off.

By public transport: Use the District line between the stations named in the Trail. You can also jump back on the tube at Cannon Street and Westminster, with all clues within 50m of a station entrance.

Need the Loo?

Safe Zone toilet access is confirmed at Cannon Street, Victoria and Earl's Court stations, so plan tactical comfort stops around those points during the mission.

Bring Your Furry Sidekicks

If four-legged operatives are joining you, plan carefully for tube travel and busy central London streets. 🐾

The mission includes stations, steps, escalators, roads, bridges and riverside sections, so keep canine recruits close around traffic, platforms, escalators and the water.

Want to Make a Day of It?

Londinium's Ancient Defences near Tower Hill

The mission begins close to a surviving section of Londinium's ancient defences, dating back nearly 2,000 years. Look out for the nearby plaque honouring Julius Classicianus, who helped restore order after Boudicca's rebellion in AD61.

Monument

Monument is more than a fire memorial in this operation's suspicious little world. Wren and Hooke originally designed it to function as a secret scientific tower for experimental spy tech, and there is said to be a hidden lab under the ticket booth.

Victoria Embankment Gardens

Slip into Victoria Embankment Gardens next to Embankment Station if your squad needs a greener pause. Basiljet passed through here during a suspicious and slightly awkward jog, and the nearby Golden Jubilee footbridges were created after a 1996 design competition.

Big Ben / Queen Elizabeth Tower

Near Westminster, the mission brings you close to Big Ben - properly titled Queen Elizabeth Tower. The Trail notes that tunnelling for the Jubilee line has made the structure lean 220mm to the northwest, which is exactly the sort of intel Agents should file away for later.

Mini Secret Agent Club

We have three super duper themed Clubs for your child to enjoy as part of their Treasure Trail experience.

Perfect for 4-8 year olds, the concept behind the Clubs is that your child will get a bundle of goodies to excite them about their forthcoming Trail experience, something to keep them entertained whilst travelling to and from the Trail, and something to be given on completion of the Trail as a keepsake.
