Hi dave,
It depends what kind of site you like, there are about 2,500 touring pitches on the Island.
If you like Club sites then the CC have Southlands near Newchurch and the C&CC have Adgestone , also near Newchurch.
Both are typically Club sites, good facilities but a bit remote and access especially to Adgestone is not particularly easy with very narrow single track roads.
If you like "all singing /dancing" sites then Park Resorts have Landguard at Shanklin, Nodes Point at Bembridge and Thorness at, Thorness near Cowes, then there is Whitecliff Bay near Sandown.
Typical commercial sites with all the facilities and the associated bits and pieces.
If you like a quiet base with just good facilities then Whitefield Forest near Ryde is an excellent site with large pitches, set in woodland but only a short way from Ryde in one direction and Sandown/Shanklin the other.
Places to visit...lots,,,,,Osborne House, East Cowes, Queen Victorias Island home: Carisbrooke Castle, Carisbrooke, Charles 1st was imprisoned there: Brading Roman Villa, one of the largest Roman Villas with amazing mosaics: Adgestone Vineyard, Adgestone: The Needles Pleasure Park and Battery, Alum Bay with its coloured sands: Yarmouth,picturesque village (one of many) and Harbour: Cowes, home of Sailing and East Cowes, birthplace of the Hovercraft: Freshwater and the Tennyson Trail:
Good shopping at Newport and Ryde (24hour Tesco at Ryde), Cowes has ainly Yachtie Shops with over priced Yachtie Gear.
Lots of god pubs and restaurants in most locations.
If you have anything in particular you want to know, ask me.
And if you are really lucky (or unlucky depending on your point of vie) you may even meet me........
or I may see you in Daventry next time I come up to see my Daughter
PS; The memory of Blckgang Chine as Carper remembers it is a long gone one, although still there, the whole lot has had to be moved inland a bit as the seaward side has all slipped away.
