Being with others is a fine experience.

Being alone with nature is a fine experience.

Do them both as you are comfortable.

Find what works for you. Do that.

For me, solo is great for experimenting, dawdling, and letting answers to my questions somehow arrive in my brain. I need to do that.

Group stuff is also fine but very different. I look to get to know people, share laughs, and learn from others. I enjoy all of that, too.

I think it is as wise to try solo hiking, starting modestly, as it is to do most things in life.
