I just relocated from north Germany into the south of Germany.
Last weekend I went hiking for the first time and visited the top of a hill close to Heidelberg. It was spontaneous and I was fascinated, and surprised by the time it took me (mostly because all was so new and exciting, but still).
From the highway driving with my car I can see that the hill I just hiked on is connected in a chain with other hills. Since I really enjoyed my first hiking trip, seeing the hill chain made the idea arise to hike along that chain for a multiple day trip.
I'm used to walking for longer distances a few times, even up to like 30KM on kinda even areas, but I've never done a multiple day trip in a hilly area.
My problem is, I never did something like this before and don't know anyone who did a trip like this before (or at least no one I am aware of having done it). All I could figure out myself so far that I would absolutely need to take with me would be warm clothing, a tent, a sleeping bag and of course provisions.
I am planning to start on a Friday morning/noon and be back in Heidelberg in the afternoon/evening of Sunday.
Now I feel quite sure that what I considered so far will be too little preparation for a 3 day trip, and probably cause me to abort my trip earlier.
Also I feel like there might be dangerous situations I could be facing that I'm not aware of, and have no idea how to prepare for them yet.
My question is:
Doing such a trip alone, as described above, what are the mandatory items I should have with me to be able to finish my hiking trip? And what are the situations I should definitely be prepared enough to face, either because they happen often enough that it is good to know about it, or situations that are dangerous enough that it would be careless to not be prepared for it?
