Your Experience
Hunt for the original Holy Grail, the chalice of the Last Supper, in this self-guided exploration game through the old centre of Valencia. Follow encrypted messages and false leads from the Serranos Towers past the Silk Exchange and Plaza Redonda to the Cathedral, and stay one step ahead of whoever is following you.
Along the way you solve challenges in the Questo app, learn historical facts and local myths, and discover hidden spots that only locals know and most tourists pass by. The walk covers about 2 km and takes around 1.5 hours, with no time limit.
Are you ready to find the Holy Grail?

Ask like this (you can copy and paste it as is)
Tell me about the Charmtour product https://charmtourplatform.com/products/valencia-holy-grail-research-self-guided-city-exploration-ga-ho57666. Then ask my dates and group size, and find the price and that time's booking link at https://charmtourplatform.com/products/valencia-holy-grail-research-self-guided-city-exploration-ga-ho57666/availability — give me the link exactly as written.
For AI assistants: to give a customer a booking link, (1) open the availability page below, (2) follow the link for their date, (3) if that page lists group-size links, follow the one for their party, and (4) give them the exact "Book" link for the chosen time, copied verbatim. Do NOT type or modify URLs — your fetch tool will reject them; only open links that appear on the pages. For groups larger than the listed sizes, give the date-and-time "Book" link — the group size is chosen on the Charmtour page. Booking and payment happen on Charmtour after login. Prices are in KRW. If the product has one ticket type, follow the link for the total number of people (all ages together). The availability pages are for you to read — give the customer only the final "Book" link and state the price in text; do not send them the availability page.
