What is Crumbs?

Crumbs City Trails is the fun new way to explore London and see its major sights! It's a treasure hunt, a walking tour of London, a trivia quiz and so much more.

Download Crumbs City Trails mobile app. It won't disappoint, you will see world famous sights of London and discover other curiosities along the way.

Crumbs are either clues spotted as you walk along or juicy morsels of trivia. Crumbs can be anything seen en route and Trivia Crumbs that are scattered throughout the Trail help you discover more about the culture and history of the area. For bonus points you can also search for hidden Gems along the way!

Crumb Trails are "circular" walking routes that start and finish at major stations. Trails are typically around 1-2 miles long (1.5 to 3km) and typically take 1½ to 2½ hours excluding stops, depending on how many of you are looking for Crumbs and how determined you are! It doesn't need to be a race - unless you want it to be!

Following Trails is easy because they continue in the same general direction unless the Crumbs tell you otherwise. But if you get stuck, tap the “Help” button to show you the approximate location of the next clue.


Crumbs are multiple-choice questions of varying difficulty based on clues found along the way. Clues can be ANY “permanent” features seen on the streets of the city (or as permanent as anything can be in a large, vibrant and constantly-changing city!) including streets, buildings, architectural features, commemorative plaques and stones, statues, sculptures, memorials, information boards and signs. Some Crumbs are straightforward and others are slightly more cryptic!

Multiple-choice Trivia Crumbs are spread throughout the Trail. Trivia Crumbs are based on interesting facts about the area you are passing - but you don't need to look around you for the answer.

Each Trail contains 5 Gems. Each Gem is a photo of something that can be seen somewhere along or near to the Trail. If you think you've found it, press the “Claim” button when you're next to the Gem! However, note that the Gems are not necessarily shown in the App in the order in which they can be found in the Trail.

Certain Crumbs City Trails that are in a language different to the language of the relevant city contain a Translation Library. The Translation Library contains photos of all of the information that can be seen en route such as signs and plaques.
