# Northern lights tours, checked against tonight's forecast > 172 guided northern lights tours in 6 countries that pass a fixed filter of 4.3 stars and 20 reviews, with prices from, duration, reviews and live odds. Canonical: https://kpforecast.com/northern-lights-tours/ Updated on: 2026-10-09 A guide drives to where the clouds open and knows the dark spots, which usually beats waiting in town. The tours on this site pass a fixed filter, show starting prices and link to Viator. The aurora odds for each departure place sit next to the list. ## In short Northern lights tours on this site come from the Viator catalogue and pass three fixed tests: a combined rating of at least 4.3 out of 5, at least 20 reviews, and a title that names the aurora. That leaves 172 tours in 6 countries, from 33 USD per person, ordered by number of reviews and never by commission. Each tour has its own page with what the price covers, the itinerary, the cancellation terms and the live aurora probability over the departure place. ## Key points - 172 tours in 6 countries pass the filter of 4.3 stars and 20 reviews - Tromsø, Rovaniemi, Reykjavik and Fairbanks have the longest lists - Cards show the starting price, the rating, the review count and the duration - Every tour page shows the aurora probability over its departure place, live from NOAA - Links go to Viator and are marked as sponsored ## Northern lights tours by country Six countries have at least one tour that passes the filter. Each country page lists its tours by departure place, with the live aurora probability for that place and a link to the country guide with the Kp each spot needs. ## The most reviewed northern lights tours The twelve tours with the most reviews across the whole catalogue. Review counts combine Viator and Tripadvisor as published in the catalogue and are read at build time, so the order changes as reviews come in. ## How the northern lights tours are chosen The catalogue is read from the Viator Partner API for each destination on the [locations page](https://kpforecast.com/locations/) that has a Viator destination id. Three tests decide what stays: a combined rating of at least 4.3 out of 5, at least 20 reviews, and a title that names the aurora, so a spa entry or an airport transfer sold in an aurora town stays out. A tour with a perfect score and three reviews is out, and so is a tour with thousands of reviews and a 4.1. Prices are starting prices set by each operator for the cheapest option and change with the date and the group size. Nothing on this page is ranked by commission. The cards are ordered by review count inside each place, and the country list by the number of tours. Every link goes to Viator and is marked as sponsored, which means this site earns a commission on bookings at no extra cost to the traveller. ## What the Kp index has to do with booking a northern lights tour A tour improves the odds in two ways: the guide drives to where the sky is clear, and the guide knows spots without light pollution. What a tour cannot do is raise the Kp index. The aurora only reaches a place when the planetary Kp measured by NOAA is at or above the level that place needs, which depends on its geomagnetic latitude. Tromsø needs Kp 1, Rovaniemi Kp 2, Anchorage Kp 3 and Edinburgh Kp 4. The [data and method page](https://kpforecast.com/data-and-method/) explains the calculation. That is why every tour page on this site shows the aurora probability over the departure place from the NOAA OVATION model, refreshed every 15 minutes, and links to the 3-day Kp forecast. A good night to book is one with a dark, clear sky and a Kp at or above the local threshold, and the forecast horizon of NOAA is three days, so booking the tour for a specific night further ahead is a bet on the season, not on the forecast. ## What a northern lights tour page on this site shows Each tour has a page with the operator's own description, what the price covers and what it does not, the itinerary when the operator publishes one, group size, pickup and guide languages, the cancellation terms, the review breakdown by rating on Viator and Tripadvisor, the live aurora probability over the departure place and three other tours from the same place. The text comes from the operator listing, read on the date shown on the page, and this site adds no reviews of its own. The example to open first is the [Tromsø guide](https://kpforecast.com/tromso/), which has the longest list. ## Frequently asked questions ### How many northern lights tours are on this site? 172 tours in 6 countries, read from the Viator catalogue on 9 October 2026. A tour appears only if it has a combined rating of at least 4.3 out of 5 and at least 20 reviews, so the count changes when ratings or reviews change and when the catalogue is read again. ### Which destination has the most northern lights tours? Tromsø in Norway, with 48 tours that pass the filter, followed by Rovaniemi in Finnish Lapland, Reykjavik in Iceland and Fairbanks in Alaska. The country list on this page shows the count per country, and each country page lists the tours by departure place. ### How much does a northern lights tour cost? From 33 USD per person for the cheapest tour that passes the filter, with most guided evening hunts between 100 and 250 USD. Prices shown are starting prices set by each operator and vary with the date, the group size and the options chosen at checkout on Viator. ### Does a northern lights tour guarantee an aurora? No. A guide drives to clearer sky and knows the dark spots, which improves the odds, but the aurora depends on the Kp index and the cloud. Many operators offer a second attempt or a partial refund, and the cancellation terms are on each tour page and on the Viator listing. ### Why do the northern lights tours link to Viator? Viator holds the booking, the payment and the cancellation terms, and pays this site a commission on bookings at no extra cost to the traveller. The links are marked as sponsored, and the filter and the order by reviews do not depend on the commission. ### Are the northern lights tour pages written by the operators? The description, the inclusions, the itinerary and the cancellation terms come from each operator's own listing on Viator, read on the date shown on the page. This site adds the live aurora probability, the Kp the departure place needs and the review breakdown, and writes no reviews of its own. ### What should I check before booking a northern lights tour? Three things: the aurora probability over the departure place, which every tour page shows live from NOAA, the Kp forecast for the next three days, and the cloud forecast for the dates from a weather service. If the night looks poor, a tour with a free second attempt or a flexible cancellation is the safer booking. ## Sources - [Viator Partner API, catalogue fetched on 9 October 2026](https://www.viator.com/), checked on 2026-10-09 - [NOAA SWPC, tips on viewing the aurora](https://www.swpc.noaa.gov/content/tips-viewing-aurora), checked on 2026-10-09
