Cambridge

Ancient drainage channels cut through vast fenland, creating a patchwork of waterways and meadows that's properly wild once you escape the A14's rumble. This slice of Cambridgeshire sits northwest of the city, where villages like Swavesey and Over dot the landscape between reedy lakes and working farms. The fens here feel enormous under big skies - quite different from Cambridge's cramped medieval streets.

Swavesey Lake draws anglers and dog walkers year-round, while the quieter Sandpit Pond and Duce's Pond offer more secluded spots for a proper picnic. The Hanson-RSPB wetland reserve is brilliant for birding, especially from the dedicated Bird lookout where you might spot marsh harriers hunting over Mare Fen. Roger's Wood provides rare tree cover in this flat landscape - lovely for a woodland walk when the open fens feel too exposed.

Overcote Fen Wildlife Area showcases the region's natural heritage brilliantly. These restored wetlands buzz with insects in summer and flood dramatically in winter, creating temporary lakes that vanish by spring. The Meridian Marker at Longstanton marks a curious piece of geographical history too.

Getting here's straightforward via the A14, with Cambridge just fifteen minutes southeast. The Guided Busway runs frequent services if you're avoiding the car. Several holiday parks dot the area - Crystal Lakes Leisure and Wyton Lakes Holiday Park both offer decent bases for exploring the fens. The countryside here rewards slow exploration rather than tick-box tourism, making caravan sites ideal for longer stays where you can appreciate the landscape's subtle moods.
