That's a common question people ask when they first consider travelling.
And of course, the answer is "It depends!"
It usually is safer to travel as a group but safety shouldn't be your only concern.
Travelling is supposed to be fun!
Remember, you are on vacation, after all.
So let's focus on yourself for a few minutes...
What's your temperament?
Where do you stand on the introvert/extrovert continuum?
The what???
Extroverts are energized by the external world - by activities, people, places, and things. They are more likely to want to travel in large groups and meet new people.
On the other hand, introverts draw energy from their internal world of ideas, emotions, and impressions. They are more likely to prefer exploring on their own or with a very small group of close friends.
If you are an extrovert, you probably wouldn't have even considered travelling alone but if you're temperament is more inclined towards the introvert side of the scale, you might have a tougher time deciding. But don't worry. You are not alone!
Travelling alone has its advantages.
Squeeze into a busy restaurant.
Assimilate into the local environment more easily.
But it can also suck at times.
You'll need to rely on strangers to take your photo. (Joby can only help you so much).
And perhaps most importantly, there will likely be no one special to share those special moments with.
But if you are an introvert, you might be willing to accept these risks and see travelling alone as an opportunity to recharge yourself because travelling with others, even those you know and care about, may take you out of your preferred element. Combine this with the stress involved with travelling, and you may place your relationships into jeopardy.
With that in mind, here are two books I suggest both introverts and extroverts read to have a better understanding of how people with different temperaments perceive social situations. You'll end up having a better appreciation of those around you as you'll be less likely to make snap judgments of one's character which could lead to misunderstandings and lost opportunities.
So is it better to travel alone or as part of a group?
It depends but I think that deep down inside, you already know the answer.
