Places to go birding in Cambridgeshire
Cambridgeshire’s birding is shaped by water: the Ouse and Nene Washes, surviving fragments of ancient fen, restored reedbeds and the flooded gravel pits that follow the river valleys. Heath, woodland and chalk-fed fen add smaller but useful changes of habitat across the county and Peterborough.
These short entries are starting points rather than live access notices. Fuller Radius & Flyway guides will be added over time, while the concise entry will remain here so the page continues to work as a complete, scannable directory.
Great Ouse and western lakes
Washland, new reedbed, former quarries and a large reservoir along the county’s principal river corridor.
RSPB Ouse Washes
The Ouse Washes is an immense strip of flood storage between parallel river banks. Winter water turns grazing land into a broad wetland used by Whooper Swans, Wigeon and other wildfowl; as levels fall, spring brings breeding Snipe, Lapwings and Redshanks.
Water is both the reason for the reserve and the main practical complication. Flooding can close trails or change which hides are useful, and much of the birding is distant. Check the RSPB’s current conditions, take a telescope and expect a flat, exposed site where wind and water levels shape the day.
RSPB Ouse Fen
Ouse Fen is being created from a working sand-and-gravel quarry beside the Great Ouse. Open water, reedbed, wet grassland and developing edges now form one of the country’s largest landscape-scale wetland restorations, with Bitterns and Marsh Harriers among the birds using the new habitat.
The reserve is still changing, so familiar routes, viewpoints and active working areas may alter between visits. It is best approached as a chance to watch a wetland being made rather than as a finished sequence of hides. Check current trails and allow time for long, open walks with limited shelter.
RSPB Fen Drayton Lakes
Fen Drayton is a chain of former gravel pits beside riverside meadows. Lakes, shallow bays, reed margins, grassland, scrub and woodland support winter wildfowl and a lively summer mix of Hobbies, Swifts, hirundines and wetland insects.
Its size makes route choice important. A short visit can focus on one or two lakes, while a longer walk links open water with the Great Ouse and quieter wooded edges. Paths use several surfaces and dog access varies by area, so consult the RSPB trail information before choosing a circuit.

Godmanchester Nature Reserve
Godmanchester combines four former gravel pits with reedbed, willow, grassland and old hedges just south of the Great Ouse. Kingfishers and grebes use the water, songbirds work the margins and migrant ducks enlarge the resident community in winter.
More than two miles of paths allow a compact visit or a broader walk linked to the Ouse Valley Way. The site is less exposed than the Washes and suits a steady local birding day, though adjacent fisheries are separate from the nature reserve and livestock may be present on the grassland.
Paxton Pits Nature Reserve
Paxton Pits is a mosaic of lakes, reedbed, riverside meadow, scrub and woodland near St Neots. It is especially well known for Nightingales in late spring, while Cormorants, Kingfishers, passage birds and winter wildfowl give the reserve a broader year-round life.
Several trails and a visitor centre make Paxton easier to approach than many fenland sites, though the reserve is popular with walkers as well as birders. Listen from public paths and avoid pressing into scrub around singing Nightingales; patient, stationary listening is usually more productive and causes less disturbance.
Grafham Water and Nature Reserve
Grafham is a large reservoir whose open water, drawdown margins, bays and western woods can hold substantial numbers of grebes, Coots and diving ducks. Passage conditions and changing water levels sometimes expose margins for waders, while the surrounding scrub and woodland add smaller birds.
The scale can make birds distant and a telescope is usually worthwhile. The western nature-reserve area is reached from Anglian Water car parks, where charges apply. Management transferred from the Wildlife Trust to Anglian Water in April 2026, so use the water park’s current information rather than older reserve pages.
Ancient and restored fens
Surviving remnants of undrained fen beside ambitious new wetlands reconnecting a fragmented landscape.
Wicken Fen National Nature Reserve
Wicken Fen preserves a fragment of ancient sedge fen and extends into a much larger restored landscape of reedbed, wet grassland and grazing marsh. The historic boardwalk shows the enclosed detail of the old fen; longer routes reveal the open scale of the Wicken Fen Vision.
Spring and summer are richest for reedbed song, insects and fen plants, while winter can bring harriers and wildfowl across the wider reserve. Decide whether you want the short boardwalk or a longer walk before arriving, then check National Trust opening, admission and trail information.
Kingfishers Bridge Nature Reserve
Kingfishers Bridge was created from farmland beside the River Cam and now combines reedbed, shallow water, wet grassland and drier banks. Its development demonstrates how carefully shaped water levels and grazing can recover fenland habitat within a comparatively compact area.
The reserve supports a strong wetland bird community, including Bitterns and Marsh Harriers, but it is independently managed and its visitor arrangements differ from those of the larger charities. Check current opening, entry and event information directly before travelling.
Woodwalton Fen National Nature Reserve
Woodwalton Fen is one of the last substantial remnants of the original Huntingdonshire Fens. Reedbed, open water, marsh, scrub and woodland preserve the complexity that was lost from most of the drained landscape, with Bitterns and Marsh Harriers among its characteristic wetland birds.
Grass paths and hides allow a slow exploration, but the reserve can flood and access notices matter. Dogs are not permitted. Link the visit mentally, if not on foot, with the restored land of the Great Fen around it: this isolated refuge is gradually becoming part of a larger connected wetland again.
Holme Fen National Nature Reserve
Holme Fen has a markedly different character from nearby Woodwalton. Silver birch woodland surrounds open meres, heath and remnant bog, while the Holme Post records the dramatic fall in peat levels after the surrounding land was drained.
Woodland and waterside birds provide the main birding interest, especially when spring song or winter flocks make the canopy easier to read. The reserve works best as an exploratory natural-history walk rather than a target site. Paths can be wet, and peatland restoration may affect familiar routes.
Nene and south Cambridgeshire
Flood meadow and city-edge lakes in the north, with smaller chalk-fed fen and grassland reserves south of Cambridge.
RSPB Nene Washes
The Nene Washes is a broad floodplain of washland meadow east of Peterborough. Spring and summer bring breeding waders, Hobbies and Marsh Harriers; winter flooding draws large numbers of waterfowl and hunting raptors. Common Cranes also use the wider landscape.
Eldernell gives the familiar public viewpoint and access along the barrier bank, but this is remote, exposed birding with no toilets and little shelter. Water levels determine how much habitat is visible, and many birds remain distant. A telescope and current RSPB access information are both important.
Ferry Meadows and Nene Park
Ferry Meadows is a busy country park whose lakes, reedbed, river, wet meadow and woodland still provide useful urban-edge birding. Hides overlook Ham Mere, Sand Martins use an artificial nesting bank and winter waterbirds spread across the restored meadows and lakes.
This is not a quiet reserve in the usual sense: paths are shared with walkers, cyclists and families, and watersports use parts of the park. Its strengths are easy access, varied habitats and the chance to fit birding around a shorter visit. Early morning usually gives the calmest conditions.
Dogsthorpe Star Pit
Dogsthorpe Star Pit is a former clay pit on the edge of Peterborough, with deep water, shallow pools, reedbed, grassland banks and scrub. Kingfishers, winter ducks and Snipe use the wet ground, while Bitterns and Marsh Harriers have occurred in the reedbeds.
The reserve is also important for aquatic insects, orchids and its Jurassic geology. Some ground is steep or dangerously soft and the water is deep and cold, so stay on established paths and observe all warning signs. It suits a focused local visit rather than a long all-day circuit.
RSPB Fowlmere
Fowlmere is a compact oasis of reedbed, fen, scrub and chalk stream within farmland south of Cambridge. Former watercress beds and the River Shep create a small wetland whose hides and boardwalk reveal Water Rails, Kingfishers, Barn Owls and a varied breeding-bird community.
Spring is strongest for song and nesting activity, while winter can bring bunting roosts and occasional reedbed visitors. The level circular trail makes the reserve easier to cover than the large fenland sites, although some sections can become muddy and current parking arrangements should be checked.
Fulbourn Fen
Fulbourn Fen protects old grassland, wet meadow, chalk-fed fen and woodland on the edge of Cambridge. Its birding is quieter than at the county’s large wetlands, but spring woodland song, wet-meadow edges and winter thrushes make it a useful local change of scale.
The reserve is particularly strong for wildflowers and insects, including an impressive early-summer orchid display. Paths are unsurfaced and livestock graze parts of the site; dogs must be kept on a lead. Approach it as a slow natural-history walk rather than a place for a long target list.
