Top-secret agents required!

Get out there on a dog-friendly Trail adventure

Spy mission Trails are the ultimate adventure for budding agents who love a good challenge. You'll embark on a top-secret assignment, deciphering clues to reveal an essential four-digit code at the end.

But beware, the mission won't be easy, and you'll have to use all of your spy skills to complete it successfully.

Using the advanced filter

In the menu, click on 'Buy a Trail' and select the region you'd like to explore or enter a place into the search bar to see all Trails within 30 miles.

Then, click on 'Filter' just above the map. An advanced filter menu will pop out on the left-hand side of the page.

If you tick 'Secret Spy Mission' and submit filters, you'll be able to see all spy-themed Trails in that region. You can even narrow it down to Trail length, type and accessibility too.

Then, simply pick the mission you and your team of top-secret agents would like to try!
