Yellow Cap

Free walking tours · London

Look for the yellow cap.

Two free, story-packed walks through the London most tours miss — from Roman walls to the scaffold where a king lost his head.

Two walks, 2,000 years

Choose your London

Each walk is about two hours, roughly 3 km on flat pavement, in a small group. Do one, or do both — together they tell the whole story of the city.

Walk 01 · The City

The Square Mile

Roman London, the Great Fire, and the birth of the modern City.

~2 hours~3 km / 2 miles9 stopsFree

  • The Roman city wall and the Tower of London

Reserve your free place on GuruWalk in under a minute. No payment, no ticket to print.

2

Find your guide

Come to the meeting point at the start time and look for the yellow cap. That's your guide.

3

Pay what it's worth

The walk is free to join. At the end, tip whatever you feel it was worth — only if you enjoyed it.

No flags, no numbered lollipops, no umbrella held in the air. Just one yellow cap — easy to spot across a crowded square, and the only thing you need to look for.

Questions

Before you come

Are the tours really free?

Yes. You join for free and there's no fixed price. Guides work on tips, so at the end you give what you think the walk was worth — entirely up to you.

How do I book?

Reserve a free place through GuruWalk using the booking links above. It takes a moment and helps the guide know how many to expect.

What if it rains?

The walks run rain or shine — London rarely stops for weather, and neither do we. Bring a coat; the route is fully outdoors.

Are they suitable for children and less mobile visitors?

Both walks are about 3 km on flat, paved streets with regular stops, so they suit most ages and fitness levels. Message us ahead if you have specific access needs.

Which walk should I do first?

Either stands alone. The Square Mile covers Roman and mercantile London; Parliament vs King covers Westminster and power. Do both and you've walked the whole story.
