Things you should carry while roaming around in Goa, well a lot depends upon your travel group or your travel companion and your tour habits. But few quintessential things which you should not forget to carry or I would say you can’t go wrong with these things: a backpack or a sling bag carrying a water bottle, a pair of extra top / t shirt and bottom, goggle, cap, waterproof mobile case and wallet with some cash n card (just for the day expenditure). Don’t forget to carry your regular medicines, if any. All these you should keep with you while roaming around in Goa irrespective of mode of transport or even if you are walking only.. keep your Id proof and also a note of your hotel / stay phone number in your wallet (yes you save it on your mobile as well but still you should keep a note on paper). I found all these very handy not only in Goa but anywhere I travel.
