Quick answer: Klook has no single policy — every product carries one of three tiers shown under the price. Free cancellation: full refund if you cancel before the stated deadline (24 hours to several days before). Conditional cancellation: you can cancel, but a handling fee is deducted, or only certain conditions qualify (for example bad weather), or only part of the booking can be cancelled. Non-refundable: no refund once booked. You cancel by opening the booking in the app and tapping “Apply for refund”; refunds go to the original payment method or Klook credits.

| Conditional cancellation | Refund with a handling fee, or only under stated conditions, or partial cancellation only | Some tickets, packages, activities with supplier costs |
| Non-refundable | No refund after booking | Discounted tickets, passes, some transport |

Deadlines
Free-cancellation deadlines vary by product — 24 hours is common, but 48 or 72 hours and 7 days appear on day trips and packages. The deadline is shown on the listing and on the booking. It runs in the activity’s local time.
How to Cancel
App: Bookings → select the booking → Cancellation policy section → “Apply for refund” → choose reason and quantity → submit. Klook confirms by email. If the button is missing, the product is non-refundable or past its deadline; contact Klook support through the app to ask about goodwill or rescheduling.
Refund Method and Timing
Refunds go to the original payment method; in some cases Klook offers credits, which can be faster. Card refunds typically take days to a couple of weeks depending on the bank and method.
Weather and Supplier Cancellations
If the supplier cancels (weather, safety, minimum numbers), you are refunded in full or offered a new date regardless of tier. Conditional-cancellation products often specify weather as a qualifying reason for a refund even when other reasons are not.
Open-Dated Tickets and Unused Tickets
Many Klook tickets are open-dated within a validity window. An unused, expired ticket is generally not refundable. Check the validity period and redeem within it.
Is Viator Better for This?
Viator applies one Standard policy — free cancellation up to 24 hours before — to most of its catalogue, shown as a countdown in the app, with stricter or All Sales Final products clearly labelled. It is simpler to plan around than Klook’s tiers. For guided tours in Seoul and across Asia (examples above), Viator also tends to have more reviews per tour. For Asian tickets and transport, Klook remains the better source. Compare: Viator vs Klook and Viator’s cancellation policy. Related: Is Klook legit?. Destinations: Seoul, Hong Kong.
