My friend and I started out in Prague phototours years ago. The original plan was one trip per month. Occasionally, excursions are ruined by a busy period or unplanned illness, so there is no pause for several months. Still, the collected images create an interesting series from which to learn a lot. And one also realizes interesting things.
What to take on a nature trip – as everywhere, there is an answer: what you can think of. But I wouldn't have to write this article. For reviewing all the photos I found that most of them take portraits of friends, natural details, sometimes animals we meet, and eventually some landscape. I often go on trips with a fixed 35 mm lens (which is also equivalent to 50 mm when converted to 35mm film). It is understandable that this focus is not ideal for landscape photography, but with details and portraits, on the contrary, quite understand.
