Best Hidden Gems in Cambridgeshire
Written by UK Hidden Gems Editorial
Updated 5 August 2026
The best hidden gems in Cambridgeshire are Peterborough Museum & Art Gallery, Woodston Ponds, Railworld Wildlife Haven, Castle Mound, Hampton Nature Reserve, Flag Fen Archaeology Park, Dogsthorpe Star Pit and Longthorpe Tower.
Cambridgeshire is often pictured as flat fen and the spires of Cambridge, yet its quieter corners hold Jurassic fossils, Bronze Age timbers and medieval wall paintings that few visitors ever seek out. Much of the region's hidden interest gathers around Peterborough, where a Georgian museum keeps marine reptile fossils and a preserved Victorian operating theatre, reedbeds along the River Nene shelter warblers at Woodston Ponds, and a volunteer-run haven at Railworld pairs model railways with a wildlife site.
Further out lie the 3,500-year-old causeway of Flag Fen, the newt-rich clay pits of Hampton Nature Reserve and Dogsthorpe Star Pit, and the medieval Longthorpe Tower with its rare painted room. In Cambridge itself the grassy Castle Mound, raised in 1068, still gives the best rooftop view in the city.
From nature reserves to ancient sites, this is a county that repays a closer look. Here are eight of the best hidden gems to seek out in Cambridgeshire.
Peterborough Museum & Art Gallery

Peterborough Museum & Art Gallery stands in a Georgian mansion of 1816 on Priestgate in the city centre, with an art gallery wing added in 1939. Its collections run to more than 200,000 items, best known for internationally important Jurassic marine reptile fossils dug from the local clay, along with archaeology, art and the manuscripts of the poet John Clare.
The building served as the city's infirmary from 1857 until 1928, and a preserved Victorian operating theatre of 1897 survives inside, one of only a few left in the country. Seek it out for the fossils and that rare surgical room.
Woodston Ponds

Woodston Ponds is a nature reserve on the banks of the River Nene in Peterborough, on former industrial land where settling ponds once took washings from a sugar-beet works. Reedbeds, pools and a small lake are now home to reed warblers, herons, ducks and great crested newts.
A boardwalk loops around the western reedbed and a platform overlooks the lake, reached from Wharf Road or by a footbridge over the Nene. The local Wildlife Trust has run it since 2003, and it is free and open at all times.
Seek it out for a quiet riverside walk close to the city.
Railworld Wildlife Haven

Railworld Wildlife Haven is a volunteer-run attraction beside the River Nene near Peterborough station, combining railway heritage with a wildlife site on a former coal yard. Indoors and out are large model railways and railway exhibits, including the preserved RTV 31 hover-train prototype, while landscaped ponds, waterfalls and nature trails with a bird hide make up the wildlife side.
There is also an exhibit on world environmental issues. It sits next to the Nene Valley heritage railway and opens on set days through the season.
Seek it out on one of its open days for trains and wildlife together.
Castle Mound

Castle Mound is the grassy motte left from Cambridge Castle, the highest point in the city at about ten metres. A path and steps lead up to its flat top, where the view opens over the rooftops to King's College Chapel and other landmarks.
William the Conqueror's men raised the mound in 1068, and it is almost all that survives of the castle. It stands beside Shire Hall on Castle Hill, open and free.
Seek it out for the best rooftop view in Cambridge, a short climb from the street.
Hampton Nature Reserve

Hampton Nature Reserve, also known as Orton Pit, is a large former brick-clay working south of Peterborough, now a mosaic of around 320 ponds among spoil-heap grassland, scrub and woodland. It is a protected site of national and European importance, best known for holding one of the largest populations of great crested newts in Britain, along with rare stoneworts in its ponds.
The wildlife charity Froglife manages it for the landowner. It is private land, so there is no general public access, only organised events and volunteering.
Seek it out through one of those organised events.
Flag Fen Archaeology Park

Flag Fen Archaeology Park is a Bronze Age archaeological site and visitor park on the fen edge east of Peterborough, preserving a timber causeway around 3,500 years old. A line of some 60,000 posts once crossed the wet ground to a platform where offerings of metalwork were made, and a waterlogged section of the original timbers is kept damp and on show in a preservation hall.
A museum displays finds including one of the earliest wooden wheels found in Britain, with reconstructed roundhouses and grazing Soay sheep. Seek it out to walk among timbers three and a half millennia old.
Dogsthorpe Star Pit

Dogsthorpe Star Pit is a former clay pit northeast of Peterborough, once dug to supply a brickworks and now a nature reserve run by the local Wildlife Trust. Around 36 hectares of grassland, scrub, reedbed, bare clay and shallow pools make up a protected site of special scientific interest, richest for its water beetles, of which more than sixty kinds have been found, along with dragonflies, kingfishers and orchids.
The underlying Oxford Clay is fossil-bearing, and a large Jurassic fish was found here in the 1980s. It is reached on foot, with the water deep and cold.
Seek it out for the insect life, keeping clear of the water.
Longthorpe Tower

Longthorpe Tower is a three-storey medieval tower added to an old manor house on the edge of Peterborough, known above all for its wall paintings. The first-floor room is covered almost completely in painted scenes from around 1330, the fullest set of domestic medieval wall paintings in northern Europe, including the rare Wheel of the Five Senses along with biblical scenes, the labours of the months and birds and beasts.
Built about 1300 of stone, the tower stands some thirteen metres to its parapet, and English Heritage looks after it. Seek it out to see paintings whitewashed at the Reformation and rediscovered in the 1940s.

Some, like Woodston Ponds and Castle Mound, are free and open whenever you like, while others, Hampton Nature Reserve, Railworld and the ticketed sites, need an open day or an organised visit, so it pays to check ahead.
Between them they tell a story of deep time and human hands, of Jurassic seas, ancient offerings and medieval painters, laid quietly across a county better known for its fens and colleges. Take your time, plan around the access notes, and let the region surprise you.
