South Coast Cycle Route
This epic cycle route makes use of signed cycle paths to take you from Southampton to Dover along England's south coast. The 160 mile route has many traffic sections running right along the coast with the remainder running as close to the sea as possible.
The ride starts at the docks in Southampton and heads east to Portsmouth, Chichester, Bognor Regis, Worthing and Brighton where there's a nice traffic free section along the famous sea front.
You continue to Seaford where there's an inland section to Eastbourne where you rejoin the coast and head to Bexhill, Hastings and Rye. There's a nice section here past Rye Harbour to the popular Camber Sands.
You continue to Lydd, Hythe and Folkestone before a nice final section takes you to the famous port of Dover.
Most of this route uses National Cycle Network Route 2 which you can also follow in a westerly direction from Southampton, though this does not run as close to the coastline. There is a nice traffic free run along the front from Christchurch to Sandbanks in Poole though.
