Best time to visit Lohagad fort is in month of rainy season in Maharashtra i.e. between June and October. In rains the place is just awesome and one will surely love the ambience that gets created while traversing to the fort. The fort is also called as the Iron fort. The fort is located approximately 14 km from Lonavla (a major tourist destination in rainy season). One of the easiest treks / hikes one can do to reach to the fort. I would suggest start the walk from base of the mountain. (Latest update is the connecting road has been tarred and cars can now go up to the fort easily) From the base the fort is approximately 3.5 km up. In rains the place is simply beautiful.
Since many people come to the fort in rainy season the base of the mountain is open to small eatery which is managed by an old lady. Few Mahindra pickup's offer you a ride up to the fort for 50/- a person. You can fill up at the bottom. Note the prices may seem at the higher side, but there is nothing nearby. The road where you stop if continued will lead to Pawna lake.
Regarding my journey, We were group of 13 people (few ex colleagues / few college friends) who planned to complete the milestone in our traveler life. The group was full of enthusiasm and we started from Bandra in Mumbai. Folks met up and kept coming towards the expressway where i was going to meet them. From start of the expressway the journey was fun filled with lots of discussion and songs. Leg pulling was main agenda. It was raining and the weather was nice and cool. The moment we reached lonavla we could see roads covered in fog and clouds almost touching us. From the expressway we took the first exit to Lonavla. After traversing through lonavala streets we took a right turn towards Amby valley (near Rama Krishna restaurant). From that point we have to just follow the road (please do not take the second right for Amby valley keep going straight)
We crossed lonavala village and kept following the road. We crossed Sinhgad Institute and kept following the road. On the fard end we could see the fort and the road now became more lonely and greener on both sides. There were many vehicles at the base of the mountain. (The road to the mountain was not built at the time). Once there we filled up our tummy and headed for the fort. Its a nice 3.5km hike in rainy season towards the fort. Once at the fort, we had to walk all the way up to the fort buy using the zig zag stairs (these stairs can be very slippery in rains)
Lohagad fort is amazingly maintained and yes it gives you a very good view from top. Scorpion's sting, is place from where you can see the Mumbai Pune expressway clearly and the winds at this place are awesome. In its full glory one can be in clouds when on the fort and enjoy the fresh cool breeze. There is a pond up where you can dive and enjoy cool water.
By evening we were back to our places having enjoyed a wonderful day with lovely friends.
