Which tours get in

A tour has to start at or after about 6 p.m. local time, or be sold as an evening or night tour, and be bookable on GetYourGuide or Viator. It needs a rating of 4.4 or higher from at least 50 reviews. Wildlife, bioluminescent and stargazing tours in remote places need 25. Where the same tour is on both sites, we keep one listing. Each tour was read on its own product page.

How the scores are made

Every tour gets a Night Score from four factors scored 0 to 10:

• Rating, 30%. We blend each rating with 150 reviews at 4.5, so a tour with few reviews sits near 4.5 until it has earned more. An adjusted 4.40 scores 0 and 4.95 scores 10.
• Review count, 10%. On a log scale: 25 reviews scores 2, 5,000 scores 10.
• Price per hour, 20%. The from-price per person divided by the hours, with hours past four not counted. $12 (€10.70) an hour or less scores 10, $120 (€107) or more scores 1. A private tour sold per group is split between two people. A tip-based walk has no real price to judge and scores 5.
• After dark, 40%. The editors' score for how much the night is the point. 10 means it only works at night or the dark is the attraction: a night safari, bioluminescence, stargazing, an after-hours entry the day ticket doesn't give. 8 is built for the night, like a vaults ghost tour or a city-lights cruise. 6 is better at night but similar by day. Anything under 4 is left out.

One program reads the same inputs for every tour and sorts every list from the result. Writers explain the order. They can't change it. How we score night tours has the formulas.

How prices are checked

• Tour prices: the from-price in US dollars shown on each product's own GetYourGuide or Viator page on October 26, 2026, per person. GetYourGuide pages were read set to dollars. The price on a given night can be higher or lower, and both sites change it by date.
• Official night openings: dates, times and ticket prices from the sight's own website, never from a reseller.
• Getting back late: last trains and night buses from the transit operator's own timetable.
• Currency: dollars first, euros in parentheses, and the local money after a semicolon when it is neither, for example $24 (€21; £18). Every conversion uses one table for the whole site: the European Central Bank reference rates of October 23, 2026, with the UAE dirham at its fixed dollar peg. For a currency the ECB doesn't publish, such as the Costa Rican colón, we use the rate the source page shows and say so. Nobody converts a price by hand.

When it gets dark, and how cold

Sunset and the end of twilight are computed for the 15th of each month with the NOAA solar-position equations, in each city's own time zone with daylight saving applied. They're accurate to a minute or two. When a page says "dark by", it means the end of civil twilight. Night lows come from the Open-Meteo historical archive, 2016 to 2025. The build renders those tables, so the prose quotes a time or two and never retypes the rest.

Operator claims

"The most haunted city in America" is a slogan. So is "skip the line". We report what an official source confirms, and when we repeat a claim, we say whose it is.

What we do when a number isn't published

We say so. We don't guess a start time, a price, a last bus or an age limit and present it as fact.
