How to Cancel or Change a Viator Booking
Quick answer: Free cancellation windows, how to actually cancel, and what happens to your refund.
Most Viator-listed experiences offer free cancellation up to a set number of hours before the start time — but this varies by listing, so check it before you assume.
Where to find your specific policy
The cancellation window is shown on the listing page before booking and again in your confirmation email — it is not universal across every experience, so don't assume 24 hours applies to a specific non-refundable listing.
How to actually cancel
Cancellations are typically done through your booking confirmation email or account, not by contacting the tour operator directly.
Refund timing
Processing back to your original payment method commonly takes several business days once a cancellation is confirmed — treat any specific number of days as approximate and check current timelines in your confirmation email.
