- Source
- The 6,975 activity listings published on WizardTrip, offered by Viator, a Tripadvisor company, collected from 16 October 2026 to 19 October 2026.
- Updates
- The study is recalculated every night from the listings published on WizardTrip; latest calculation on 23 October 2026. The rankings grow as new listings go online.
- Prices
- The “from” price shown for each activity, converted into euros at the exchange rate of 23 October 2026 (26 currencies).
- Activities included
- 5,853 activities. Excluded: private tours (979), whose price is often for a whole group, multi-day tours (143) and activities with no price or no longer available (0).
- Calculation
- For each city, country and type, the median price: half of the activities cost less, the other half more. Unlike the average, the median is not skewed by a few very expensive activities.
- Thresholds
- A city is ranked from 30 activities analysed, a country from 100, a type from 50. Only actual cities are ranked: islands, regions, lakes and natural sites are left out of the city ranking but count towards their country.
- Reliability
- A comparison (private tour, skip-the-line) is only published if at least two thirds of the cities or comparisons point in the same direction as the median gap; skip-the-line also requires at least 10 comparisons. Otherwise it is hidden until there is enough data.
- Limitations
- Prices are those shown on a given date: they vary with the season, the day chosen and the number of participants. The same price may cover different durations and services.
