As of October, I've solo traveled in 3 continents: Europe, Australia and North America. So now that I've got a little experience under my belt, here are some of the things I noticed about traveling solo around the globe:
Sharing a common language definitely made navigating the cities easier, and there was decent public transport within the big cities, although it was pretty pricey to get around.
Europe has the best public transport by far, but if you're traveling to a country where you don't speak the language, it can be a bit tricky to navigate by yourself. There were some cities where I definitely would have been lost without having Lexa to figure things out with.
Obviously, I feel a bit more comfortable because I'm traveling within my home country and am around people who speak the same language as me. On the other hand, it's much more expensive to travel here and can be significantly more difficult to get around as public transportation still has a long way to go in most cities.
No matter where you're trying to go, solo travel can be a great option. Who wants to wait around for friends or family to be available when there are awesome travel opportunities all the time?! If I had waited around for other people, I wouldn't have gone to New Zealand/Australia, wouldn't have taken a vacation in California before moving and starting a new job, and would've missed out on at least one country in Europe. Solo Travel can have its ups and downs, and can be totally intimidating for first time travelers (or let's be real, even people who have done it several times before), but it's totally worth it!
