Villa Borghese Gardens, Rome
Valle Aurelia, Rome, Italy
This could be any street in any city.
Mixed-era apartment buildings. Imposing stone architecture at turns. Cobblestones and pavement following no particular logic. Crush of cars and scooters. Cafes. Hairdressers. Passerby dressed in scales of gray.
So, what makes this different from any other street—any other city?

As we made our way along a dry riverbed, through native South African fynbos vegetation, toward a spectacular (but, again, arguably nondescript) stretch of shoreline, my friend put to me a similar question. Not quite verbatim, it was this:

Most mountains are pretty similar. Most cities are pretty similar. There are trees and rocks and wide sky spaces. There are streets and cafes and passerby in scales of gray. So, what makes these mountains different? If we can go hiking at home, why ever go anywhere else? And if we do go, how do we choose? 

Why these mountains?

The question was philosophical in nature. My friend is nearly as avid a traveler as I.
I would like to offer three answers to these questions—one of which sounds nice, one of which I believe most strongly, and one of which I feel, irrationally, to be true.
It doesn’t matter which is which.
First, terroir. Terroir is a French term I fell in love with while studying the anthropology of food. Essentially, it claims that taste is deeply rooted in place—territory. The elements unique to a given locale—water, specific bacteria, culture, human traditions, soil, weather, everything—combine to create the particular circumstances in which a given food item is produced. And we can taste it. While terroir is a culinary concept, I believe it can just as easily apply to cities, landscapes and really anything else.
Thus, these mountains are made unique by an intangible yet undeniably meaningful agregate of water, culture, air, bacteria, soil, and human idiosyncrasy. 
Why go anywhere? Terroir.
Second, intuition. Some part of our deepest self knows where we need to be. It doesn’t make sense, and it can’t be proven, but those who have experienced will swear that the voice of intuition is real—and that it is always right.
So, how do we know, how do we decide where to go? Instinct.
Or third, the difference isn’t out there at all. It’s us. The mountains are, more or less, all the same. Trees and rocks and wide sky spaces. The cities, too. We, however, change, and we can understand that change by observing its reflection in the places we visit—or rather our experiences of them.
What makes these mountains different from all the rest? We do.
Or, most probably, the answer is some combination of the three.
What makes these mountains different from any others? Nothing, or precious little. Yet, they will be different, because we will change—always.
Why go anywhere else? Terroir. 
And if it’s all the same, how do we possibly decide on one mountain, one city, one street over another? Oh yes, intuition.
Maybe this could be any street in any city, but it isn’t. It’s this one—the one I’m in. And it is utterly unique, both for its composition of individuals, elements and other intangibles, and for my experience of it, in this particular moment. No other street in any other moment will ever be this. I don’t know why I’m here—and not in another street, city, mountain—but I trust the voice that called me.
