Thank you @consigliori for your reply, I didn't knew there is a Karachi based 4x4 group. Where do I sign up for membership?
Yes of course those are private properties, I am talking about dirt roads going through the areas and leading to some good scenic spot (non-private) maybe to stop by, and do some 4x4 tests, low range 4x4, high rage 4x4 etc. As in city we never get the chance to engage 4x4. Use winches which some of our 4x4 members have but no opportunity to use.
I've been watching some 4x4 Australian channels on YouTube recently, and thought why not here we can do something like this? We can explore good spots around Karachi, take photos / videos of our 4x4 rigs, and share them with location and our reviews.
Watch these two episodes, and I know you'll be thrilled to go out and do some 4x4:
My last travel was to Gwadar, and on way back we discovered some good spots, Kund Malir Beach for example. I believe there are tons of spots in interior Sindh too, just need explored and shared so others can have a look or visit by themselves.
If you @consigliori visited some good location that qualifies for another visit, that would be cool too. Visiting same location in different seasons makes it a new spot too
