The length of a solo trip depends on various factors such as your destination, budget, and personal preferences. A weekend getaway might be perfect for a city break, while exploring a new country might require a few weeks. Some travelers even embark on months-long journeys. It's essential to plan your itinerary based on what you want to see and do, and ensure you have enough downtime to relax and reflect. Remember, the goal is to enjoy the journey, not rush through it.
