Winter hiking requires careful planning and proper equipment to handle dark and unpredictable weather conditions. It is important to hike with a buddy, tell others your plans, and bring essential gear like warm layers, food, water, and traction devices. When hiking, stay on designated trails to avoid damaging sensitive environments, and follow regulations regarding waste disposal, firewood collection, and wildlife interactions.
