I'll be backpacking Europe, and plan on doing a lot of hiking in both Switzerland(early november) and Norway(Early-mid december).

The thing is, i'm flying solo and while i'm not an passionate hiking i've done a fair bit but only in groups organised by someone else.

What are some tips for hiking solo?
I'll be hiking places that seem to be fairly touristy places (Preikestolen as an example.).

Is it advisable i join into a guided hike , or just be a man and go it alone?

Pic related, it'd be nice if i had someone to take photo of me at my destinations.
