Brighthelm is in the centre of Brighton, just off Queen’s Road between the station and the sea.

From North Road (e.g. coming from the station), it looks like this …

You are strongly discouraged from driving into central Brighton. Brighthelm has a small car park but it is gated – on Sundays, groups have to manage this themselves and Open Sky cannot do this from the garden. There is a public car park next door on North Road, but it is expensive.
Central Brighton is well served by public transport. The bus hubs of Churchill Square, North Street and Old Steine are all within 10 minutes walk. Brighton station is 5 minutes walk away. There are also a good number of cycle racks at Brighthelm.
Brighthelm and the garden are accessible by wheel-chair.
