I spent 4 nights in Arambol (Harmal) beach, which is the northernmost main beach in Goa, keeping in mind that Goa is about 100km long from north to south, as the crow flies. Plus, if you want to leave by long-distance train or plane, you have to back to/near Margao/Madgaon anyways (originally I wanted to go to northern beaches because I though it would be a little more “on my way” to Mumbai, but no).
Cows on the beach (a few minutes down the beach – not right by the restos!)
Tasty granola-fruit-yoghurt breakfast with coffee at my hotel (with view of beach)
Fresh fish selection at a resto on the beach

Sunset behind rocky outcropping (which looks like a big open-mouthed fish jumping out of the water)
