We took our bikes on a weekend to Wells Next the Sea a little while back and had a lovely pootle along the coast and marshes around there. Quite a bit of the coast path is byway or bridleway and although the riding isn’t challenging it’s good fun if you don’t mind mixing up the lanes and bridleways.
From Wells there is some nice riding along the coastal woods to Holkham Gap on the Peddar Way. We did some riding on the beach there and then we went up through the Holkham Estate and then along the old Roman Road before striking off towards Burnham for lunch. We came back to Wells on an inland loop via North Creake, Gallows Hill and then down Market Lane. If you take a look at an OS map of the area (or Bing Maps in OS Mode) the routes are all pretty obvious – some of it is on Sustrans Route 1.
