Let me start with a teaser of what I saw
For a long time I have been wanting to see the northern lights, also called aurora borealis. During two of my vacation trips - one to Alaska and other to Iceland, I thought I'll be able to see them, however I was out of luck and didn't get a chance to see them even though the forecast was showing a good chance of seeing them. In US there are very few places where they are visible and trips to Finland/Norway didn't work out so far.
When I moved to Canada, i started researching for places where I could see them and being close to the pole, there should be many places in theory. I had seen reports of people seeing them in 2-3 hrs of driving distance from Toronto region. Churchill in Manitoba was one of the most popular places where they say you can see the lights 300 days in a year. That sounded like a guaranteed viewing, if we went on any of the tours in that region. The tours were however very expensive as Churchill is not an easily accessible place and it's not just famous for northern lights. This part of Canada is known for polar bears and hence most tour operators run their tours as a combination of polar bear discovery and northern light tours. The polar bear tours take you on an ice explorer truck into the heart of bear territory and at night they also run northern light viewing tours. The prices were in the range of 50-10k CAD, so this option was ruled out. After some more research we narrowed down on Yellowknife and Whitehorse (until few months back I had not heard of these two places). A cab driver told me he thought these were cities in some other country

Yellowknife was in Northwest territories and Whitehorse in in Yukon, two different provinces/states. So flights options were going to be quite different. Yellowknife was at a higher latitude than Whitehourse, so we decided that Yellowknife was a better option. Once the place was decided, we had to get down to the actual plan of how many days, what tours and other activities were possible. Temperatures were in the range of -40, so it was certainly not same as the winter we had seen in Toronto (although the temperature had dropped to -20s on some nights in the past few years).
The Plan
We decided to do a 4 days and 3 nights trip. Timing was important as we didn't want to be there when it was snowing, but low temperatures meant no precipitations and hence no clouds and more visibility in the sky. The aurora seasons starts from November and lasts till early April. Looking at flights, we decided that first week of march would be a good time and also gave us some cost savings. We found a direct flight from Toronto for onwards and return journey, so that it saved us any time needed for layovers at other airports.
Now that the dates and flights were decided, we started researching for tours and their reviews. There are two types of aurora tours in Yellowknife - first that takes you to a campground where tipi/tents have been arranged and all you have to do is sit there and wait for the arurora to appear and second, where you go aurora hunting. After going through pros and cons of each tour operator, we decided to go with the second type with northern light tours. This operator did a combination of tent based and aurora hunting tours, if you took multiple day tour. For a single day tour, you would get whatever the plan was for that night. We also decided to book a dog sledding tour and a Yellowknife city tour, since we didn't want to sit at the hotel the whole day. The final plan looked like the below one
Day 1- Arrive in Yellowknife, take the night tour
Day 2 - City Tour, take the night tour again
Day 3 - Dog Sledding, take the night tour
Day 4 - Depart from Yellowknife.
Day 1
We had a morning flight, that would reach by noon in Yellowknife. There was a last minute aircraft change due to which there were many seat changes. Our initial aircraft was an A319, but we ended up getting an A321, so the crew was making lot of adjustments and people were given the option of sitting anywhere since half of the aircraft was empty. After some delay, we finally took off and landed on time in Yellowknife. The airport there is quite small and looks like a small warehouse. There was no bridge so we had to walk to the gate. The moment we were outside the aircraft, the temperature was around -35 or -40 and our noses had started to freeze (since everything else was covered). We managed to get into the building quickly and had to wait for half an hour to get our bags (everything is manual there). We were told that the hotel had a shuttle from the airport, but we didn't find anything, so had to rely on a tourist shuttle to reach the hotel after collecting our bags. Since we reached few hours earlier to checkin time, we had to leave the bags with the hotel and went to the in-house restaurant for some food. After a while we managed to get 1 room ready for use and the second one was ready in another hour. The rooms were good and spacious and we had one room with a full kitchen. We had taken winter clothing on rent from the tour operator, so he came down with a bus full of winter clothing. Except for the jacket and pant, theater things were just basic and we didn't feel that much confident with the quality and heat protection. We noticed that some tours were giving canada goose jackets (which are the best rated jackets and cost like 2-3K per jacket). To be better prepared we had purchased battery operated gloves, socks and heating pads for shoes (again never heard of these items before this trip, to be honest).
Since we paid for the winter clothing, we took whatever he provided. After a quick dinner, we got ready for the first night's aurora tour. A bus came along with 2 people (driver and guide). This was supposed to be a hunting tour for that night. We went about few places, a frozen lake, some viewpoints. Initially we saw only faint ones, but at the last stop, we saw a fairly good aurora and stopped there for at least half an hour. The guide also took photos of all people on the tour (this was a complimentary benefit with this tour). I didn't carry my DSLR on the first night, so relied on the guide's camera and my own phone. Without a tripod the photos were really shaky and blurry, but with worse than freezing temperatures the phone performed well. One of our iPhones got switched off when it was left in the jacket pocket. Samsung still held up the entire night.
The tour was over by around 1:30 AM and we came back at the hotel by 2 AM. Being in mountain time, we were already sleepy, so we decided to wake up late and then plan for the next day.
