30 kilometres away from Ratnagiri, Purnagad is a sea fort that is believed to be Shivaji Maharaj’s last phase of development, hence the name (Purna meaning complete + gad meaning fort). A one day trek, this is a comparatively short trek, about 15 minutes long, leading up to top where you’ll enter through the western gate, further reaching the eastern gate that opens towards the sea.
How To Reach: Drive down to Ratnagiri, and then take a bus from there to Purnagad, which is around 30 kilometers away. The drive's long (around 9 hours) but the greenery will give you company and the smooth roads make it better.
Best Time To Visit: During the monsoon and winter season.
