Longitude Festival shares all you need to know

The most important things to know are the transport options for getting to and from the south Dublin venue.

Public transport is by far your best bet for getting there. Shuttle buses will run from Custom House Quay to Marlay Park from 13:00, leaving on the hour every hour until 18:00 (and not 19:00, as had previously been announced). The journey back to the city centre will begin at 21:00, and buses will depart as they fill. Tickets can be booked online for €9; they'll cost €10 on the day.

Dublin Bus will also get you there; Routes 16, 116 and 161 pass the Grange Road entrance, while Routes 14 and 75 will get you to Balinteer Shopping Centre, around 15 minutes from the site.

As traffic restrictions will be in operation, taxis will be making pick-ups on Stonemason's Way. These traffic restrictions are also why organisers do not recommend driving. If you have to, give yourself plenty of time. Delays are inevitable, and parking is limited; car-parks are located off College Road and open at 12.30 each day. There will be temporary road signs to guide traffic, so switch that sat-nav off!

Finally, there is a reminder of the basics. If it's wet, wear rain gear and wellies. If it's sunny, bring a hat and sun-cream. Note: it's Ireland. You might be best covering all bases. There is no phone charging facilities, so arrive charged up and ready to go, and take note of the usual regulations regarding what won't be allowed on site. Finally, make sure any under-16s are accompanied by someone 18 or over.
