Ilha de Rachol.
I'm a Goan guy living in South Goa for past 22 years lost in love with the nature and so I spend my time going places to see what is the best you can get and what is the best you can learn from the people of that particular place and I feel the only place one would find peace and calmness in Salcete is "Rachol". "I call it home away from home"
About the People:

People of Rachol are mostly engaged in farming, fishing and there are few people like the young generation working out of these places to making their living better. Rachol is also famous for its churches. Locals say that the first church of Salcete Our lady of Snows is in Rachol and there is a ferry point behind this church. People of Rachol also are engaged in Fish breeding.
What to see?
Rachol is an evergreen place and the locals here are very friendly and loving. The famous Portuguese colonial fort has vanished leaving behind the traces of the main gate which is one of the historic attraction for all. One visiting Rachol should also take a look at those few Portuguese houses beside the road still well maintained.
I got a Plan for You!

See You Soon.
And the last but the most pleasing thing is the sunset. Spend a day in Rachol and I promise you, you'd definitely visit this place again someday soon.
Go Explore!

There are many more places I have not mentioned about, because I want the people to visit this place and try interacting with the locals and try finding the places which I have not mentioned, as we all know the feeling when we find something without knowing about it, its like " Yes I explored this place :P " And yes when you visit this place please do not dirty the place and if you find that the place is dirty there is no harm in cleaning it.
