GRAILTRAIL: Quest for the Holy Grail (Self-Guided Adventure Walk)
Overview
**NEW - AUDIO NARRATION ON ENGLISH LANGUAGE VERSION**
Join our quest for the Holy Grail, following a trail of mystic symbols, cryptic sites and secret signs hidden in plain sight. This trail is built on historical fact — if it’s not true it should be! The story it tells takes you way past the point of mere coincidence. What you discover will astonish you.
Bring your scepticism to Paternoster Square and take a leap of faith. By the time you reach Covent Garden, you will be convinced!
This sacred quest is to be savoured, not raced. It would make an epic pub crawl too! The directions are easy to follow. The clues are visual and rooted in the cityscape. All you need is your phone — and an open mind.
Fully playable in 11 languages (English, French, German, Italian, Spanish, Portuguese, Russian, Japanese, Chinese, Korean, Arabic) — no guide required.

This self-guided walking trail is a symbolic quest through London’s forgotten sacred geography. Inspired by medieval legends, Templar secrets, and half-buried histories, it follows the Grail’s journey from Glastonbury to its current location — through alleyways, chapels, relics and invisible lines.
Along the way, you’ll uncover connections between early Christianity, Celtic saints, Knights Templar and mysterious alignments. The clues are visual and embedded in the world around you — patterns, names, symbols, and the spaces between them.
The trail is 5km, step-free and ends in Covent Garden.
The story is fiction. The places are real. There’s no need to believe. All you have to do is notice what’s staring you in the face.
Fully playable in 11 languages (English, French, German, Italian, Spanish, Portuguese, Russian, Japanese, Chinese, Korean, Arabic) — no guide required.
