Denham Country Park

The River Misbourne rises in a field on the outskirts of Great Missenden in Buckinghamshire, passing through Little Missenden, Old Amersham, Chalfont St Giles, Chalfont St Peter and under the Chiltern railway line and the M25 motorway to its confluence with the River Colne just north of where the Colne is crossed by Western Avenue, the A40 road. It falls by around 94 m (310 ft) in the course of its 27 km (17 mi) length.

Denham Lock Wood is a 6.3-hectare (16-acre) biological Site of Special Scientific Interest (SSSI) next to the Grand Union Canal, and near Denham in the London Borough of Hillingdon. It was notified in 1986 and is managed by the London Wildlife Trust on behalf of Hillingdon Council. It lies within the Colne Valley Regional Park.It is a poorly drained wet woodland and fen site which is skirted by the Frays River. The main trees are alder and crack willow in the wetter areas, and elsewhere oak and ash with a shrub layer of hazel. In winter wildfowl are visible and in spring many flower species. Invertebrates include red cardinal beetles, banded demoiselles and the rare and protected Desmoulin's whorl snail. The balsam carpet moth was added to the list of British species when it was found at the Wood in 1955, and it is only known at one other site in Britain.Access is by a footbridge across Frays River from Frays Farm Meadows, which is also an SSSI managed by the London Wildlife Trust, south of the Wood. Access to the Meadows is by a stile on the east side of the Grand Union Canal at Denham Lock.

Frays Farm Meadows is a 28.2-hectare (70-acre) biological Site of Special Scientific Interest near Denham in the London Borough of Hillingdon. It was notified as an SSSI in 1981, and has been managed by the London Wildlife Trust on behalf of Hillingdon Council since 1999. It is part of the Colne Valley Regional Park.Frays Farm Meadows are a set of fields bounded on the south by the A40 road and on the west by the Grand Union Canal. The Frays River goes north through the site before turning west toward an old railway embankment that runs north from the A40, dividing the site into three parts: the western fields, the area between the embankment and the river, and the fields east and north of the river. The site is accessible to the public apart from fields on both sides of the embankment. Access to the western fields is by a stile on the eastern bank of the canal at Denham Lock. From there a path through Denham Lock Wood (another SSSI run by London Wildlife Trust, north-west of the Meadows) gives access to the northern and eastern fields. Frays Farm Meadows provide a window on the medieval world, never having been intensively farmed. They are one of the few remaining examples of unimproved wet alluvial grassland in Greater London and the Colne Valley. The linear features, river, embankment, ditches and hedges, contribute to the rich diversity of plants and animals. Cows and horses graze in order to improve conditions by churning up the ground and encouraging pooling of water. Mammals on site include the nationally endangered water vole, and there are birds such as snipe, cuckoos, and a barn owl. Plants include marsh horsetail, ragged robin and arrowhead.Frays Valley Local Nature Reserve partly covers the same area as the SSSI.

Buckinghamshire Golf Club, containing the Denham Court Mansion, is a golf club near Denham, Buckinghamshire, England, United Kingdom.It is accessed via Denham Country Drive off the M40 motorway near the junction with the M25 motorway. The golf course and surroundings form part of the Denham Country Park, an area which the poet John Dryden called "one of the most delicious spots in England". The mansion is set in a course of 226 acres, designed by the former Ryder Cup captain John Jacobs. The golf club was established in 1992. The River Misbourne flows through the course. The club hosted the Senior Tournament of Champions on the European Seniors Tour from 1996 to 2000, the Andersen Consulting World Championship of Golf European Final in 1997, which was won by Colin Montgomerie, and the ISPS Handa Ladies European Masters on the Ladies European Tour since 2012.

Uxbridge Alderglade is a 2.9-hectare (7.2-acre) nature reserve in Uxbridge in the London Borough of Hillingdon. It is managed by the Herts and Middlesex Wildlife Trust.The site is a narrow strip of land between the Frays River and the Shire Ditch, and it was formerly a railway embankment on the Uxbridge High Street branch. It is wet woodland of crack willow and alder, with areas of marsh. Plants include birds-foot trefoil and small toadflax, and there are mammals such as the rare Brandt's bat, as well as stoats, weasels and moles.There is access from Braybourne Close and from a footpath which starts in Harefield Road opposite Gravel Hill, and then crosses the Frays River by a footbridge.

The Denham Roundabout is a road junction in Denham, Buckinghamshire. It was originally opened in 1943 in conjunction with the completion of the new Western Avenue route into west London. The Western Avenue took over the classification of the A40, with the previous route to London, via Uxbridge and Ealing, being reclassified as the A4020. The roundabout also included a new link to A412 that formed part of the outer London orbital route. Since 1973, the westbound A40, now flows into the M40 motorway at this point. The roundabout below facilitates junction 1 (J1) of the motorway to connect with the westbound continuation of the A40, together with the intersection of the road from Uxbridge (A4020) and the road from Slough to Watford (A412).When the M40 from Denham to High Wycombe was built, Western Avenue was extended at high level to make an end-on join with the motorway, and a larger roundabout was built below the bridges carrying the motorway. When first laid out, the roundabout had the traffic going round it clockwise in the usual way, but as traffic volumes built up, the layout was altered so that the traffic moved round the roundabout in both directions, making it a ring junction with roundabouts at the points that other roads join the main roundabout.

Denham is a village and civil parish in the unitary authority of Buckinghamshire, England, approximately 17 miles (27 km) from central London, 2 miles (3 km) northwest of Uxbridge and just north of junction 1 of the M40 motorway.

Harefield Road was a proposed London Underground station on the western branch of the Central line beyond its current terminus at West Ruislip. Under the London Passenger Transport Board's 1935–1940 New Works programme, the station would have been built alongside the existing Great Western and Great Central Joint Railway (GW&GCJR) line between West Ruislip and Denham as the penultimate station on the Central line's extension from North Acton.Like many other new stations built by London Underground in the outskirts of the capital, the construction of the station was intended to stimulate new housing developments in what was a rural part of Middlesex. Works on the extension were postponed during World War II and, after the war, green belt legislation was introduced to limit the expansion of urban areas. The area beyond West Ruislip fell within the designated Metropolitan Green Belt, and, as the intended housing developments were no longer allowed, the extension beyond West Ruislip was cancelled.
