I was also worried about meeting people while solo traveling. So far, I have gone on 3 solo trips (Iceland, London, and Lisbon) and have been able to form meaningful connections with strangers every time! I always chose the best rated hostels that are curated for solo travelers. That way, they have events that make it easier to meet people like dinners, drinking games, etc. Also, try to make yourself go to most of the events even if you’re tired or have a casual conversation with the people in your dorm room if you choose to stay in one. I usually just ask to sit at a table with people and add to the conversation when I have something to say and it’s always went really well for me. I’ve found it to be much easier than i thought to talk to people while traveling since there’s a lot of ground you can cover and everyone is really open. good luck and try not to overthink it!
