We only managed to get the earliest tickets, so we set off while it was still dark, taking a taxi. Upon arrival, we went straight to collect the oxygen cylinders and bottled water included in our package, and rented thick down jackets. Remember, always arrive at your reserved time for the cable car; otherwise, you won't be allowed through the ticket check. If you've finished exploring the main cable car and it's not time to take the Spruce Meadow cable car yet, you can take a bus to other attractions or simply wait. Because it was cloudy and rainy that day, we only reached 4506 meters for photos. At around 3000 meters, we didn't feel much, but at 4000 meters, breathing became quite difficult, and we felt a bit dizzy. Using oxygen occasionally was necessary; in the end, we didn't even finish one bottle, and we gave the other to the hotel. Spruce Meadow and Blue Moon Valley are both beautiful and photogenic!
