Sims 4 players can access the Mt. Komorebi Upper Mountain if the Snowy Escape expansion pack is installed. To access the mountain, players will need to travel to the bathhouse in Yukimatsu district of Mt. Komorebi. Once they reach the onsen, they will need to use a mobile phone to start the mountain excursion social event. During the excursion, players will come across several hidden locations as they climb the mountain until they reach the very top.
