Car or coach
From London or the West (M40/M25)
Take the A40/M40 (M25 J16) to the Swakeley’s road roundabout, signed towards Ickenham. At the small roundabout turn left into Harvil Road. Continue across the railway bridge and the road goes downhill, then up and to the left. The Dews Lane is on the left just before the start of the bend. Continue along Dews lane to the end. Beware of barriers out side of normal opening hours.
From the South (through Uxbridge)
Go north to the Swakeley’s roundabout and proceed as above.
From the North (Watford/Harefield/Rickmansworth)
Take the A412 from Rickmansworth through Maple Cross to Denham Green and turn left at the traffic lights. Continue to the small roundabout at the end of Moorhall Road and turn right. Dews Lane is on the right after ¾ mile, about 200 yards past the left turn into New Year’s Green Lane and the Recycling Centre. Continue along Dews lane to the end. Beware of barriers outside of normal opening hours.
Given that HOAC is a considerable distance to walk from the nearest stations, and that the Metropolitan and BR lines allow bicycles to be carried free outside peak hours, it is practical to arrive by train and cycle the last few miles if you are coming a long distance.
The local tube stations have free copies of the Sustrans cycle route maps which are worth picking up.

From Denham or the West and A40
Cycle or take the train to Denham Green on the North Orbital Road (A412) and take Moorhall Road across the canal to Harefield. Turn right at the roundabout and continue until you pass New Years Green Lane and its dump on your left. The turn-off to HOAC is signed shortly afterwards on your right.
Do NOT take the Western Avenue/A40 between the A40/M40/A412 Dehnam roundabout and the Swakeley’s roundabout – this is a section of motorway in all but name and there is no safe cycle path.
From Harrow and the East
Cycle to Old Eastcote (from Harrow Town Centre the recommended route is to take the Pinner Road through North Harrow, where there is a new cycle lane on the left-hand pavement, go down Imperial Drive (also with cycle lanes) and then take Village Way/Eastern Avenue/North View to Eastcote and continue along Elm Avenue/Pembroke Way/Park Avenue to Ruislip. All these are minor-roads running parallel to the Metropolitan railway line.
At Ruislip you are probably best to avoid the NCR down Ickenham High Road and take a short-cut up Bury Street, and turn left into Ladygate Lane. At the end turn left and continue up to the Breakspear Arms pub, where you turn right and then left into New Year’s Green Lane. Beware of the poor quality of the road surface. This takes you to Harvil road, where you turn left and then right into Dews Lane.
If you are further north, note that there is a good (signed) cycle route from Old Eastcote to Ladygate lane, cutting out the B466/Eastcote Road, using the Evelyn Avenue and other back streets.
From Uxbridge and the South
Cross the A40 at Swakeley’s roundabout and follow the B467 until you get to Harvil Road on your left. Follow this across the railway until you get to Dews Lane on your left (it’s the first turning after you’ve left the houses behind). This is not a pleasant route on a bicycle – a narrow fast road. If anyone knows of a better practical route from Uxbridge, using the canal tow-path for example, please contact us.
If you want to arrive by tube and bus go to Uxbridge station on the Piccadilly and Metropolitan lines. From here you can take a U9 bus that will stop on request at the end of Dews Lane, from where it is a 600m walk down the lane to the Centre.
The nearest tube station is Ickenham (also on the Metropolitan/Piccadilly lines), from where it is a 3km/2mile walk or a cab ride (a cab from Uxbridge is 5km/3miles).
The British Rail station at Denham is 4km (2.3miles) if you stick to walking along roads.
