This is a gentle coastal walk linking 3 historic coastal towns (Margate, Broadstairs, Ramsgate) on the Isle of Thanet (NE Kent). Much of the walk is along low chalk cliffs with views over the channel, with several secluded coves. At low tide, you can walk along the beach between them. The 3 resorts are very busy on sunny days, but the rest of the coast is much quieter.
This is the farthest corner of the Isle of Thanet is arguably where the east coast of England meets the south coast, though the gently curving coastline makes it hard to identify a precise turning point.
For much of the way it is possible to choose between walking on top of the 20-30 metre high chalk cliffs ("cliff top level"), or at low tide, walking along the beach or promenade below ("beach level"). Although this stretch of coast is largely built-up, there is a wide strip of open grass along most of the cliff top. The beaches are sandy and flat - the tide goes out a long way.
The walk can be done "clockwise" (starting in Margate) or anti-clockwise (starting in Ramsgate or Broadstairs). Clockwise allows 2 possible endings, so you can choose between a medium and a longer walk. Anticlockwise give you 2 possible starts.
These notes, and directions below, assume "anticlockwise". Check the tide times. The Margate end of the walk is nicer at low tide. It is a series of bays which are joined together at low tide. At high tide, you need to use the cliff top path between them, at low tide, you can walk along the beach. If starting in Ramsgate its the middle / end that's best at low tide, if starting in Margate ("clockwise"), its the start / middle which are best at low tide.
Apart from the small part to/from Ramsgate station, the route is pretty easy - just follow the coast, swapping between the cliff top path and the beach as you wish and the tide dictates!
Ramsgate has an interesting old town area, a harbour with a harbour arm to walk along, with a bistro at the end, and a large new Victoria Pavillion (A Wetherspoons pub).
There are some quiet beaches with beach cafes on the way to Ramsgate, its a mix of sea path and slippery rocks or cliff top path through a park.
Broadstairs also has an interesting old town, as well as a sandy beach and links to Charles Dickens. After quieter beaches, there's a choise between a short inland detour or rocky beach walking below (at low tide).
Next is a series of sandy coves, you can walk between them at low tide, or use the cliff top path above. Of these, Botany Bay is the most secluded and prettiest beach - its western end (only) with sand dunes is discreetly used by naturists. From the west, its entrance (from cliff top level) is easy to miss. By the main entrance (at its eastern end), are some picturesque stacks and an arch.
From here, its a concrete promenande, passing a tidal bathing pool all the way to Margate. Margate, while not so historic/pretty as the others, has a large new art gallery (free), a harbour arm protecting the beach (bars), and many pubs and cafes.
This walk is also being promoted as the Viking Coastal Trail cycle route ([link 1], [link 2] ) - the first website has a good map, and a PDF of the route leaflet, with interested history about the route
