Klook Review: Booking Milan Tickets from Asia

Klook is an experiences booking platform aimed first at travellers from Asia. It was founded in September 2014 in Hong Kong, where it is still headquartered, by Ethan Lin and Eric Gnock Fah; it passed a billion-dollar valuation in 2018 and filed for a US listing in November 2025. Its pitch is a single app for everything a trip needs. For Milan, the question is not whether Klook works but whether an Asia-Pacific platform gives you anything extra in a European city where the local specialists are strong. Its own about page carries no destination or download figures, so we quote none.

Why Klook matters for Milan visitors from Asia

Milan is a major long-haul destination for travellers from China, Japan, Korea, Singapore, Hong Kong and Taiwan — fashion, football, the lakes, and Malpensa as a Schengen gateway. Booking behaviour follows the traveller, not the destination: if your flights, rail passes, SIM and Tokyo or Bangkok activities already live in one app, adding a Duomo ticket there is the path of least resistance, and support in your own language and time zone is worth real money when something goes wrong at 22:00 Milan time.

That is Klook’s genuine advantage, and it is about the account rather than the catalogue.

Payment, currencies and languages. The help centre is explicit about this, and it is the part worth reading before you assume your usual wallet works. Klook takes bookings in 38 currencies, the euro among them, and charges anything else in US dollars or, for unlisted Southeast Asian currencies, Singapore dollars. Cards carry the widest support: Visa, Mastercard, JCB, American Express, UnionPay, Discover, Diners Club and Cartes Bancaires. Apple Pay and Google Pay are global; PayPal is tied to dollars and iDEAL/Wero to euros; and Alipay, WeChat Pay and the regional Asian wallets are listed only for renminbi and Hong Kong dollars — so the famous Asian payment rails are not what you get at a euro checkout. You cannot split one booking across two cards or wallets, and the help centre itself is published in 45 locale versions, Italian included.

The Milan catalogue in general terms

Klook’s Milan offering follows the standard reseller shape: cathedral tickets, Leonardo’s Last Supper as a guided visit, city sightseeing, day trips towards Lake Como and the Swiss border, airport transfers and city passes. The inventory comes from the same European suppliers that stock every other marketplace, so what you are choosing between is interface, price presentation and support — not a different Duomo. Its city pages refused our automated checks, so we give no product count: open the Milan page in your own browser and compare the two or three tickets you actually want against the prices on this site.

Two structural notes hold regardless:

• Nobody resells the official Cenacolo Vinciano ticket. The €15 official entry exists only on Vivaticket; guided visits with a reserved place are the alternative on every platform. Our Last Supper page sets out the release calendar.
• The Duomo terraces are capacity-limited and timed. A cheap ticket for the wrong hour is worse than a fair ticket for 09:00. See Duomo tickets and Duomo rooftop.

What you can verify about the process

Klook’s help centre states that instant-confirmation activities produce a confirmation email within five minutes, while activities needing supplier approval are confirmed within 24 to 48 hours; vouchers are also stored in the app under Account then Bookings. For a timed Milan attraction that 24-to-48-hour band matters — do not leave a non-instant booking until the night before.

On cancellation, Klook publishes terms per activity rather than one company rule, and its help centre sorts every listing into three buckets: free cancellation, where you cancel yourself from the Bookings page inside the window shown on the voucher; conditional cancellation, where you have to meet the stated conditions and go through customer support; and no cancellation, where nothing is refunded. Nothing is refundable once the activity has been used, and support asks for the booking reference plus documents — a cancelled flight, a medical note — for anything conditional. Read which of the three you are buying on the listing, because the badge is the only place it appears.

Independently, Trustpilot shows Klook at 4.5 out of 5 from 28,550 reviews, with 77% five-star and 10% one-star ratings, and the company replying to essentially all critical reviews within a day (checked September 2026). Reviewers praise the interface, speed and promotional pricing. The complaints are operational rather than ethical: inventory that disappears between selection and checkout, prices that shift between search and payment, glitches at peak times, and a checkout with too many steps.

Verdict

Strengths: one account for a whole multi-country trip, support oriented to Asian markets, frequent promotions and credits, strong independent review scores, clear confirmation timings. Watch-outs: a European catalogue that is resold rather than sourced, availability and price wobble at checkout, non-instant products that need up to two days, and per-activity cancellation terms we could not verify. Bottom line: if Klook is already your travel app, book Milan there with your eyes open and compare the cathedral ticket against the official price first. If you are starting from scratch for Milan alone, an attraction-first platform is the shorter route to a timed slot.

Our partner alternatives

We link commercially only to Tiqets and GetYourGuide. Prices checked September 2026.

Cathedral entry plus rooftop access is €26 on both partners, delivered as an instant smartphone ticket; the Tiqets fast-track version of the Duomo complex adds an audio guide in nine languages including Chinese and Japanese, which is the practical detail for a group travelling without an English-speaking guide.

For visitors doing Milan in two days, the Milan City Card at €46.50 bundles the cathedral, the Duomo Museum, San Gottardo, the terraces, the Museo Nazionale Scienza e Tecnologia Leonardo da Vinci and the Pinacoteca Ambrosiana with an audio-guide app — note that San Gottardo is excluded on Wednesdays and the card is non-refundable. Compare it against single tickets on our tickets and passes page before buying.
