If you are arriving by air
Try to arrange a flight to London Gatwick airport (LGW), as it is only 20 minutes drive from Sirius.
You can get a taxi from Gatwick to Sirius for about £20. There is also a regular bus service to
East Grinstead, which is the nearest town to Forest Row, where Sirius is located. If you fly
into another airport, such as Heathrow, Luton or Stansted, you can catch a bus to Gatwick and
then get a taxi or bus. Note: Taxis from Heathrow to Sirius directly may cost more than £120.

If you are arriving by rail
The nearest  railway train station is East Grinstead, which is 4 miles North of Forest Row.
You can then get a taxi to Forest Row for about £6, or catch a bus. Trains depart from
East Grinstead for Victoria or London Bridge stations in central London approximately every
30 minutes. There are also railway stations nearby in Crawley and Gatwick. 

If you are arriving by road
Forest Row is on the A22 which runs from London to Eastbourne on the South coast. When
you reach Forest Row, take the turning signposted 'Hartfield', 'Tunbridge Wells' (B2110) into
Hartfield Road, from the mini roundabout in the centre of the village. After about 50 metres,
you will see The Foresters Arms pub on your left. Turn immediately left after the pub into
Station Road. Follow Station Road straight on past the park and the timber yard, which
are on your right. Immediately after the timber yard, turn right into Forest Row Business Park.
Riverside is the large building on the right at the end.
