I visited here recently in novber month. It is a beautifull small island accessible through motor boats or jetty.
The best part of the island is that its well maintained and you can easily see a deer or peacock or a rabbit around you. They are freely spread out there.
One can easily explore the island in 5 to 6 hours.
You can also hire a vehicle which will take you to every sightseeing spots. But I would recoend you to walk and explore by your own as its not too big.
There are no hotels to stay there. You can find one or two restaurants there but they are expensive.
