Edinburgh Old Town and Underground Vaults

A 2-hour guided tour descending into Edinburgh's network of stone vaults built beneath the Royal Mile and Grassmarket in the 18th century. These underground chambers stored goods, housed temporary prisons, and sheltered the city's poorest residents. Your guide leads you through low, candlelit passages while explaining real accounts of the people who lived in near-total darkness. Claustrophobia and extreme cold are genuine concerns; most visitors find it unsettling but absorbing. Best for visitors wanting underground access. This is a moderate activity lasting 2 hours. Group size: max 15. You meet at Mercat Cross, High Street. Key highlights: Access to 18th-century vaults most tourists don't see, Authentic stone architecture and period graffiti, Real stories of poverty, imprisonment, and survival.

Are the vaults actually haunted, or is that just marketing?

No verified hauntings - the 'ghost stories' are marketing. What's real: people lived and died here in poverty and disease. The psychological impact of being underground in the dark is enough. Most visitors feel genuinely unsettled, which is the appeal.

How cold are the vaults and what should I wear?

Vaults maintain 8–10°C (46–50°F) year-round due to stone and lack of ventilation. A single sweater isn't enough; wear a thick jacket. Thermal leggings under trousers help. Many visitors underestimate the cold and regret it midway through.

Can I take photos in the vaults?

Yes, natural light and torch-only photography is allowed. Flash is technically permitted but strongly discouraged - it's disruptive to other visitors in the dark and damages the distinctive experience everyone paid for.
