Cycling or Rambling (Walking) in the UK. When in the countryside older groups of organised ramblers walk canal towpaths or cut across watersheds on horizons the most famous being Kinder Scout or Stanage Edge in the Peak District. On Helvelyn in The Lake District there is a steep drop on Striding Edge. Cycling occupies not these heights but the lower valleys, Neanderthals, networked and signposted across the United Kingdom. Since many of these are on disused railway tracks, then these link ailing or modern cities offering a journey through history. Remember it is possible to lock a bicycle and climb into the wilderness. The Downs in the Iron Age bald hills, the only clear path in a country covered in forest. The new park of South Downs stretching from Winchester to Eastbourne is centred on the South Downs Way for rambling and walking. Cycle with an Ordnance Survey map flanking or crossing the Downs to the coast.
When visiting cities on a bicycle park and lock the bicycle and visit the art gallery. This can be spiritual, biblical especially if the pictures are big as in John Martin in Newcastle and London Tate Britain. A gallery is often cheap or free lost in another world for a whole afternoon. In Newcastle the gallery was from plans built facing the wrong way causing the designer woe. Some of the best paintings are in the basement not on show. Aberdeen, Glasgow, Edinborough, Carlisle, Newcastle, Manchester, Liverpool, Birmingham, Oxford and Cambridge all have notable art galleries.
London has a whole district of specialist galleries around Exhibition Road accessible by bicycle from Hyde Park. Walkers and ramblers can alight at South Kensington underground station with a special dedicated tunnel from there under Exhibition Road.
Coventry has a new transport museum with every British vehicle and bicycle ever made. In Durham the cathedral and the river incised meander walk, city itself is more interesting.
