Frampton Marsh is an RSPB reserve of grazing marsh, lagoons and reedbed on the edge of the Wash, just south of Boston. The scrapes and pools pull in big numbers of waders and wildfowl, and it’s rated among the best places in England to watch them, with hides and a visitor centre to work from. Entry is free and the trails are flat and mostly accessible. Boston station is about 7km to the north.
