Willow Tree Fen

Situated between Baston and Spalding, Willow Tree Fen is a relatively new nature reserve, transformed from arable land to a more traditional fenland landscape of shallow meres, seasonally flooded pastures, hay meadows and reedbeds.

What’s on

PLEASE NOTE: Emergency gas works are currently taking place at Willow Tree Fen. The seasonal route through the meadow is currently closed, but all other routes remain unaffected. Parking in the first car park is limited to 2-3 vehicles, but the bottom car park is clear. Apologies for any inconvenience.

Dogs are permitted on a short lead.


The main ‘T-shaped’ path is a hard surface farm track. The other paths are mown grass paths.

Please note: Willow Tree Fen has been suffering from a range of antisocial behaviours. As a result we have decided to keep the barrier down and the track closed when we are not on site in order to reduce this type of behaviour and prevent it from increasing. The site still remains open to all visitors but parking will be restricted to the top car park when we are not on site. We are sorry for the inconvenience this causes to visitors and will keep the situation under review.

Opening times

Reserve open all year. Please note, the gate to access the car park will close out of office hours.

Group visits

Any organised groups wishing to visit a reserve must fill in a Group Visit Form at least one month in advance of their visit. You can find the form on our group visit page.

Alternatively if you are looking to bring a school group, please contact info@lincstrust.co.uk

Car park

There is a small, free car park by the entrance to Willow Tree Fen which is opposite Bank House Farm (PE11 3JH) and over a small bridge.

Habitats and species

Since its purchase in 2009, species from the surrounding Baston Fen and Thurlby Fen Slipe have now also colonised Willow Tree Fen.

Despite being a drained arable farm prior to 2009, the fenland reserve has developed fast. The natural depressions in the field hold water during the winter and attract large numbers of waterfowl such as wigeon, teal, mallard, and waders including lapwing, redshanks and snipe.

Walks and trails

There are three waymarked routes around Willow Tree Fen ranging from 1.6 to 2.6 miles. The main ‘T-shaped’ path is a hard surface farm track and the others are mown grass paths.

Willow Tree Fen is also on the route of the Macmillan Way - a long-distance route from the Lincolnshire coast to the Dorset coast.
