The topography is typical of the shoreline between Gary and Michigan City, consisting of sandy beaches and sand dunes, ridges and wooded valleys inland. Developed areas are now mostly covered with natural and planted vegetation, lawns or other ground cover, paved streets and driveways, houses, accessory buildings, and a variety of landscaping and retaining walls.

The numerous park areas are densely wooded or remain open with natural vegetation, except those used for recreation. The land is mostly dry, except for one inland pond, Polliwog Pond, and marshy areas near Long Lake in the westerly section. The town's corporate boundaries also include portions of the adjacent National Lakeshore Park, in the northwesterly and southerly sections, which remain in their natural state.
