When to use this
Use when the itinerary needs a view walk rather than another ferry hop.
Why it matters
Varenna Turismo references help explain Castello di Vezio as a hill-route and view stop that belongs in a Varenna-local day only when uphill timing is planned separately.
Confirm before you rely on it
Check current castle opening days, admission rules, last-entry timing, uphill walking route, weather, footwear, heat, after-dark return, ferry or train timing, and whether the villa day still works if Vezio is dropped.
