Hiking

Embark on an easy hike through the Floodplain Forest Nature Reserve, a route that spans 2.7 miles (4.3 km) with a gentle elevation gain of just 51 feet (15 metres). You can expect to complete this loop in about 1 hour and 5 minutes, enjoying serene wetlands and lush greenery along the way. As you follow the path, the River Great Ouse will often be in view, offering peaceful waterside scenery. Keep an eye out for the historic Iron Trunk Aqueduct, a notable landmark on your journey. The landscape, once pasture, now teems with diverse plant life and is a fantastic spot for birdwatching.

Before you set out, be aware that the reserve is designed to flood after heavy rainfall, which can make certain sections of the trail temporarily wet and difficult to pass. However, the water typically drains within a couple of days, so conditions usually improve quickly. Parking is conveniently available at the nearby Ouse Valley Park car parks, providing easy access to the reserve. Plan your visit during drier periods for the most comfortable experience.

This reserve is a haven for wildlife, especially if you enjoy birdwatching, as various wildfowl frequent the area. You might even spot Konik ponies grazing peacefully in the open meadows, adding to the unique charm of the landscape. The transformation of this former pasture into a thriving ecosystem makes it a special place to connect with nature. It stands out in the region for its commitment to natural flood management and biodiversity.

Floodplain Forest Nature Reserve is part of the wider Ouse Valley Park, which also comprises Stony Stratford Nature Reserve and Iron Trunk Aqueduct. A plethora of wildlife is found here, from bird species like herons, kingfishers, peregrine falcons and barn owls, to mammals like foxes, badgers, weasels and otters.

There is a scattering of trees, though you'd be forgiven for wondering where the 'forest' is, but give it time. In 2017 and 2018 the Parks Trust planted many alder and willow trees to screen the lakes. One day this already vibrant nature reserve will be even more wild in character.

Iron Trunk Aqueduct

Highlight • Monument

Also known as Cosgrove aqueduct, the Iron Trunk Aqueduct was built in 1811 to carry the Grand Union Canal over the River Great Ouse. Two cast iron trough spans cross the river, held aloft by a single central masonry pier.

There is a wealth of excellent walking in the surrounding Ouse Valley Park, including two excellent nature reserves. A popular itinerary is to link the Iron Trunk with the village of Cosgrove, with a visit to the Barley Mow pub.
