I went to this fort last week with my friends for a bike ride.
The road from pune to lohagad fort is very good and has got a lot of scenic beauty, reach to fort before 4 pm as it is not allowed to enter in fort after 5 pm and it has got a small trekk and a number of small and medium waterfalls.
Also it is convinient to reach via train but one has to walk fron railway station to the fort as no other convince is available.
It was a good experience going there, a must visit place near pune
