Third Tunnel of Aggression

Worth it if you're into Cold War history and want a tangible bit of geopolitical tension—the 4.9 rating from over 142k reviews suggests people genuinely find it compelling. Go with a guide (73 Viator options available) rather than solo, since context transforms the tunnel from 'hole in ground' into something that actually lands; paid entry is standard for this sort of thing, so budget accordingly but don't expect budget pricing.
