I saw a hot spring and got a very lucky guess, I can imagine there are a lot of hard ones in there yeah!

My country was El Salvador. I would not have guessed it (I kept trying equatorial countries). I had to reverse engineer the URL encoding of the embedded map.

Spoiler: There is !1d and !2d, followed by coordinates.

Mine gave me a place a Qatar, which doesn't even seem to have real photos but 3D renders instead: https://goo.gl/maps/YynAc2JSfKJzeAwWA

I had albania which was easy -- there was a nearby poster with some writing on, and a short ddg led to albanian sites.

Google a street name.

If it lands on a street it lets you roam around, but others only let you look and zoom around, they are harder if not impossible for mere mortals.
