The north-west coast of Mumbai houses the relatively-isolated Madh Island beach—part of a cluster of fishing villages. A watchtower built by the Portuguese in early 17th century called the Madh fort stands to this day, and is a breathtaking structure overlooking the sea. This quaint beach in Mumbai boasts of treacherous tides and swimming could turn out to be a dangerous affair. However, for those seeking a peaceful retreat from urban realms, Madh Island beach is highly sought-after.
