Went to Sinhgad on weekend. It is around 25 kms from Pune and the ride to the fort is good. Better roads would have made the journey more pleasant and of course the rainy season would be good for a second trip. You can see whole of Pune and Khadagwasla lake/dam from the height and it makes a good sight. Sachi also told me that in night the reflection of lights in the lake makes a good sight. Another trip in night is due soon :-)
Sinhgad has had an interesting history and I had read about it school textbooks earlier. I agree that it would have been difficult to conqueror but the place is definitely not 'well preserved'. Almost all the forts in Rajasthan are in much better shape than this one. Its only history of the fort and natural surrounding that attract tourists to visit and revisit, tourism department has definitely not done anything to promote this fort.
Anyone coming to bbay for techfest?
