The Coco beach is situated at the mouth of the Nerul River on the Mandovi Estuary, directly opposite Panaji. There are a number of restaurants here and the 10 or so restaurants are popular in the afternoon, but quiet at night.
Further down the estuary there the two small beaches of Quedevelim and the Reis Magos Church and Reis Magos Fort (this impressive Portugese Fort was a prison for some years and is no longer open to the public).
When you are at Candolim, you can visit Coco Beach and Nerul, which are just 5km away from the beach. Here you can enjoy a drink and a bite at St. Francis Shack or just enjoy boat rides up the Mandovi River.
Apart from this you can visit Quincy corner which is a nice place in Candolim, where you can listen to ambient music in a delightful decor of palm tree and coconuts, very away from the road, and people.
There are a number of nice shacks in Candolim from Bistro sun and sea-side to Pete's cafe. Also the Oceanic, Sea-side mama Cecilia are nice and away from the crowd. If you want to listen to reaggae music try Pedro shack's, just down the Goan heritage hotel. Sometimes they make nice parties also there.
