Bradenham Butterfly Trail

Walking trail

This is a 2.3 miles (3.6 kilometres) circular walk from Small Dean Bank near Bradenham. The walk takes in a variety of woodland, grassland and scrubland habitats, which are managed by the National Trust to sustain biodiversity. Bradenham Woods, Park Wood and The Coppice have been designated as a Site of Special Scientific Interest. Twenty-eight species of butterfly have been recorded here, including small blue, Duke of Burgundy and dark green fritillaries. Marbled whites are abundant and there are many more common species.

Ideal conditions to see butterflies

What you will see will depends on the time of year and on the weather conditions. Warm, dry days from April to September are likely to be more rewarding. The walk also offers extensive views of the Chilterns Countryside near Bradenham.

National Trust car park in Smalldean Lane. Grid Ref. SU823989


From the National Trust car park in Smalldean Lane, turn left onto the lane, following it downhill towards Small Dean Farm. This is usually a very quiet lane, but please keep a look out for traffic. After 250 metres, you will reach the buildings of Small Dean Farm. Here turn left following a footpath sign. Take a track between some out buildings and continue until you reach an open field. Here turn left and follow the path in a straight line along the field boundary for 130m, towards a wooden gate in a gap in the hedge ahead of you.


Go through the gate and follow the path steeply uphill through an area of grass and scrub vegetation. To your right is a field with numerous round anthills built by yellow meadow ants.

Chalkhill blue (male)


At the top of the field, go through another wooden gate and up a short steep slope into Park Wood to meet a crossing track. Turn right along the track, which initially curves left, then eventually curves to the right as it heads steadily uphill before levelling out and then then descending again. Ignore all side paths and follow the track for about 400m through the beechwoods until you reach a fork. Take the right fork, which is effectively straight ahead. After a short distance you will reach another gate leading out of Park Wood into a field.

Speckled Wood - Pararge aegeria


Turn left, following the edge of the field, with Park Wood on your left. The path heads steadily downhill until it reaches a wooden kissing gate next to a field gate. From here you will have a clear view of Bradenham Village in the valley below. Go through the gate, taking the second track on your left that leads up a short slope to a metal field gate and a metal kissing gate.

Brown Argus - Aricia agestis


Go through the gate and follow the edge of the field uphill, again with Park Wood on your left. On your right there are distant views of Bradenham, Bradenham Valley, and as far as West Wycombe Church. After you have passed the path’s summit it starts to descend to another metal kissing gate.


Go through the gate and head downhill across an area of grass and scrub vegetation. Take care as the first few metres after the gate are very steep and the path can be slippery after wet weather. On reaching the bottom of the slope, turn left onto a wide track and head towards a set of wooden gates.

Essex Skipper - Thymelicus sylvestris


Head through the gate and continue following the wide track gently uphill, ignoring branching paths. After 300 metres, the path curves to the left. You soon see a short, steep wooded bank to the right of the track with a chain link fence running along the top and with old pillboxes behind. This is the boundary fence of RAF High Wycombe at Walters Ash. The track bends left uphill away from it then levels out. Continue following the main track as it winds through an area of beech woodland, then an area of relatively young birch trees and then back to mature beech. At this point, you meet again the boundary bank and fence. When this comes to an end and on a left hand bend in the track look out for a clear but narrow woodland footpath on your left, which descends through the beech woodland.

Silver-washed Fritillary


Turn left onto the woodland path, following it as it winds its way downhill for about 100 metres. You will soon see a wood gate ahead of you. Go through the gate into the nature reserve at Small Dean Bank. Follow the steep downhill path across Small Dean Bank, back to the car park where you started.
