I would say minimum…It’s old saying travel light. And in Goa, it’s very much applicable as well as practical. Let’s talk about what you should carry when you are going on beach hopping or to enjoy a particular beach.. You can go to beach(s) by walking, by two wheeler or four wheeler.. whatever the medium is, assuming you already applied a good sunscreen (if it’s still daylight), a good slipper, a light beach carry bag, an extra pair of top / beach sarong / beachwear / t-shirt, undergarment, goggle, cap/hat, drinking water, one photo ID proof and some cash (no cards). These are I always found helpful and sometimes holiday saving.
