This means you will need:
spikes, ice axes, crampons, ice picks, GPS app, mobile battery, face mask,knit cap, cold-weather gear, gloves, snow goggles, hiking boots, avalanche transceiver, helmet, etc.

Snowshoes cannot be used yet because there isn’t enough snow accumulation. They damage the hiking trails.
