Well, I now a lot of places, which I found by myself, those well known and those not widely known. Finding them is easy and simple mainly. I search Google satelite view (or other satelite views like Bing) in a scale of 200m-500m step by step (and of course look at the available pictures if they are here) looking for unusual structures, places or so.
Of course such searching takes some time, but you can find fascinating places, e.g. some years ago I found a place when a part of a destroyed rocket, probably unsuccesfully had started from Baikonur and touched down in Uzbekistan (unfortunately now it is no more available, probably taken by the army).
Sometimes it is not so simple as some places are hidden by their nature - years ago I was looking for Shakhty cave for a long time on my two travels as there was almost nothing about it on the net (I found the info in the book "Бегущие по скалам" by V. Ranov) and found only 3 (!!!) photos on Google including 2 of the interior. Fortunately on the second journey I recognized a characteristic rock outside seen in the background of the third photo so I could find the cave near. But it costed me almost 2 days of exploring two big valleys each about 50-70km long and over a dozen their smaller sidevalleys. And now Shakhty is easily available (even there are the signposts) and there are a lot of pictures of it on the net. But that time my satisfaction was great (you should see me leaping with joy).
Sometimes I also search for interesting or even unclimbed peaks on my way across the Stans as I'm a climber (there are still many, not very high but anyway over 5000m, even 6000m). I check the peaks in libraries and consult with the specialists like Vladimir Birukov, one of the authors of the Soviet military maps (Pamir, Tien-Shan) from Russia, or Jerzy Wala from Poland (Karakoram, Hindukush), the author of Karakoram maps.
Also searching the net (not only forums, but libraries etc.) is very helpful - especially in Russian (which I know). In that way I found for example "Стрелы Устюрта" (Ustyurt Arrows) a dozen years ago.
Another way is monitoring local news for any interesting themes, on culture or history, an example according to Shakhty (it is about the "new Shakhty"):

Of course, I haven't been in all such places, so I still have to do (explore) in Asia.
Also you can just take a paper map (for the Pamirs the Marcus Hauser map is perfect; Russian military maps are more functional for people who know Pamirs and Tien-Shan a little bit more and visited them more than once or twice and want to explore) and try to visit some remote valleys in situ. It is much more fascinating and rewarding when you find something "majestic" by yourself than from a guidebook which often propose not too much (the Odyssey guidebook "Tajikistan and the Pamirs" by Middleton/Thomas is an exception).
And last but not least and maybe most important - books. There are about 200 books in my library on Central Asia (mostly in Polish, but also Russian and English).
But if you are first time visiting the Stans even keeping on the main roads like Pamir Highway and some side roads (e.g. Kingob, Vanch, Bartang, Wakhan, Aksu valleys; for these look at the Marcus Hauser map) is really addictive and full of impressions. It will take your time and attention a lot.
