The Vashi creek is situated on the North side and Mahim Causeway is lying on the south side. On the western side, there is Arabian Sea and on the eastern side, the boundary of Thane. This administrative unit forms the limits of Mumbai Suburban District and was part of Goa which was under the control of Portuguese up to 1771 - 1772.
