Well overall I can say that "Gleaming white sand, pristine blue water, swaying coconut palms and betel nut trees and gentle breeze producing a serene and calming effect", this is not a dream but the enchanting place called Diveagar.
For the one day trip just arrive at Diveagar. Check-in and rest. In the evening, visit Diveagar beach and local food joints to enjoy Konkani dishes.
But yes one thing I would like to add here is as usual beach is not maintained by locals so you can expect garbage at the entrance of beach as well as on the beach.
- Always carry your extra clothing to the beach. Don't be lazy. You will be tempted to get wet in the waves.
- Carry something to sit - like a mat or a stool, if you don't want to get wet
- Carry extra cash, if you plan to eat, because everything is super-costly. A green coconut water costed Rs. 40/- (which is twice the price in Pune)
- Don't miss your camera(s)
Travel makes you free :)
