In general, Switzerland, including the Swiss Alps, is a safe country with lower crime rates compared to other countries. At night, the streets are well-lit and public transport runs reliably, even on mountain routes. However, as a solo female traveler walking alone at night, it's important to stay aware of your surroundings and follow the same safety precautions you would anywhere else. Additionally, areas with wildlife activity can pose risks, so it's recommended to avoid unfamiliar trails at night. In winter, slippery paths and early nightfall can also pose challenges. Switzerland's emergency services are efficient and responsive should you ever need assistance.
