Newtown remained small, but this has preserved its original layout, which is of historical interest. There are two square ponds by the boathouse, which were dug as salterns as part of the former local salt industry. The harbour and salterns have since become a habitat for fish native to the Isle of Wight and its surrounding waters, with large populations of Flathead grey mullet living in both the harbour and the salterns. Although there are a number of private residences still in use and the harbour is still accessible and used by small to medium vessels, Much of the land Newtown is situated on is now under the ownership of the National Trust, with the hamlet being at the centre of a nature reserve built around the old harbour. Newtown is popular with tourists and birdwatchers, as numerous uncommon native species use the salt marshes to nest.
