1. Greenwich to Crawley
This section of the route follows the Waterlink Way through South-East London on quiet residential roads. After leaving Greater London the route becomes more rugged but this improves onces you have passed under the M25. The route continues on to Redhill and then Crawley where you can connect with Route 20.
2. Crawley to Eastbourne
The section between Crawley and Eastbourne takes you east to East Grinstead along the traffic free Worth Way and then through Forest Way Country Park. This takes you onto Groombridge following a disused railway line with fabulous views of the River Medway. The route then continues on through Eridge and Mayfield before joining the traffic free Cuckoo Trail at Heathfield. The route takes you all the way to Eastbourne Park and along the Eastbourne coast.
Things to see and do
This route runs south from Greenwich out of London through Lewisham (the Waterlink Way) to Crawley, and then via East Grinstead and Eridge to Heathfield and Eastbourne.
Please note: Much of the traffic-free on Route 21 is not suitable for a road bike. There are stretches through woodland without a tarmac surface which may require dismounting, as well as sections requiring bikes to be carried over a railway footbridge and kissing gates.
