We run tours every day, in all weathers. And we have guaranteed departures. Let’s put it another way: when you book onto a Mercat tour, you’re going on a Mercat tour. No last-minute cancellations. No minimum quotas. We’ve got a tour to suit everyone. From a quick self-guided 45-minute whip round the vaults, to a full two-hour evening of exceptional storytelling. Daytime or evening, weekday or weekend – we definitely have something for you.
