The regatta is rowed on the Albany Reach section of the river as shown on the map below. The site is accessed from the river end of Aragon Avenue.
Cars without competitor boats on their roofs (with the exception of Disabled Badge Holders) will not be allowed down Aragon Avenue as this residential road has to be kept clear for trailer access. Disabled Badge Holders should contact email@example.com to get an Albany Reach Parking Pass.
The postcode of the bottom of Aragon Avenue (for satnav purposes) is KT7 0PY, but only vehicles towing boat trailers, vehicles with boats on their roofs, and some non-towing school minibuses will be allowed down Aragon Avenue.
When choosing your approach route, please note that there is no right turn into Summer Road if you are heading north up Hampton Court Way. Therefore, if taking that route, I suggest you turn right into Embercourt Avenue, and then take the 3rd left at the railway bridge roundabout into Speer Road (although this too tight a turn with a trailer), which will bring you out at Aragon Avenue, or continue north over Hampton Court Bridge, go right round the roundabout, and then you can turn left into Summer Road when heading south on Hampton Court Way.
Unfortunately, despite trying, the regatta has been unable to secure a dedicated parking area for spectators/competitors cars not transporting boats. Some parking is available in nearby streets: please be extra careful to park courteously, observe the Highway Code, and not to block driveways, park too close to junctions etc. The map below shows a Pay & Display carpark in the center of the village where you can park all day for the bargain price of £2. From there walk through Church Walk to Summer Road and thence to the regatta site. Hampton Court Railway Station has a car park, cost £6 per day for cars, which is about 10-15 mins walk away.
Coaches (as in luxury buses, not rowing instructors) should disembark their passengers between the entrance to the KGS Sports Ground just to the east of Summer crossing, and the top of Aragon Avenue, and then go and park elsewhere. There is coach parking at Hampton Court Railway Station which costs £12 per day.
