geography & geology


The Isle of Wight covers an area 380 km², with just over half designated as an Area of Outstanding Natural Beauty. 258 km² of the island is farmland, perhaps due to the island’s extended growing season. The Isle of Wight is roughly diamond-shaped, with a vertical chalk ‘backbone’ running through the middle of the island from The Needles in the west to Whitecliff Bay in the east. Either side of this is an almost complete sequence of sedimentary rocks dating from 120 million years ago to present day. Sedimentary rocks form over millions of years from layers and layers of rocks building up on top of each other – these lines of sedimentary rocks can be seen in the cliff faces all over the island.

A lot of the Isle of Wight is made up of hard sandstone and limestone rocks, as well as some clays an mudstones. These, particularly the Gault ‘blue slipper’ clay, are much softer, which accounts for the rapid rate of cliff erosion found on the island. This phenomenon is notable at Ventnor and Blackgang. Another aspect of these soft rocks is how, especially on the south coast, rivers have cut into them to form gorges. These are known locally as ‘chines’. One of the most famous was Blackgang Chine, where the river ran through the gorge into a spectacular 70-foot waterfall. Unfortunately cliff erosion destroyed virtually the entire gorge. However, the chine at Shanklin is in a much better condition and visitors can walk down through the chine’s spectacular scenery. The Sandown Breezer goes through Shanklin Old Village, where the chine entrance, is during the summer season as does the Shanklin road train. Out of season the number 2 and number 3 buses stop outside Somerfield, a short walk from the Old Village.

the Needles





The Needles are the island’s most famous landmark, and by far the most outstanding of the island’s natural attractions. As well as the Needles themselves, there are several other spots of interest in the vicinity. Just up the cliff from the Needles, overlooking the Solent, is the Needles Batteries, an excellently preserved Victorian fort.

On a calm day, a boat trip goes out from Alum Bay beach to the Needles, passing through the gap where the third rock used to be situated. The beach at Alum Bay features multi-coloured sands, which Queen Victoria found interesting. You can reach Alum Bay beach via a chairlift which goes from the Needles Pleasure Park situated at the top of the cliff. There are various activities for all ages at the Pleasure Park, including children’s rides, a glass-blowing house, a sand shop, and a sweet manufactory.

The route 7 buses serve the Needles Pleasure Park, as well as the Needles Breezer and Island Coaster routes. The Needles Breezer bus also serves the Needles Battery, driving along a spectacular winding coastal road on the way.

the Needles Battery

The Batteries are bunkers constructed between 1861 and 1895 for coastal defence against a threat of invasion by France, and were equipped with gun placements on the top of the Battery. The cannons are still in place today.

The site was re-used for defensive purposes during both World Wars, with a powerful searchlight being installed in a room under the Battery - this room can still be accessed today. During the late fifties the New Battery was used as a testing site for space rocket engines. In 1976 the National Trust acquired the Batteries and restored them before opening them to the public.
