Traveling solo is a fantastic idea, but if you currently feel uneasy about it, perhaps considering it when you're a bit older might be more suitable. Deciding to travel with strangers may not be the safest choice. It's true that solo travel, especially for a girl and someone of your age, can raise safety concerns.
However, traveling alone or with a group, the experience can be extremely enjoyable. If you decide to go, thorough preparation, such as familiarizing yourself with the destination and utilizing smartphone tracking features, is crucial for a safer journey.
