Can I pick both?
There’s appeals to both of them.
Beaches have seashells. The air smells significantly different. If diving, one can also view coral reefs or other creatures under the water. The water and sand feel very good between the toes.
Mountains can also be sources of fresh air and mineral water. There might be caves that can be explored.
And mountains would (hopefully) be too high for a predator to catch you.
I’ve heard that the views from mountaintops are stunning.
Alas, all I have in terms of the latter is videos online.
Nothing we see in a video can capture the wonder of seeing it in person.
