Everybody stays on-site throughout Lost Paradise, with camping access included in the price of your ticket (sorry, Lost Paradise does not allow pass outs - exit anytime, but you cannot re-enter the event).
If you wish to drive to the festival, you will have to purchase a Parking Pass and then park your car in the car park, which is no more than a 5-10 minute walk from the campsite and amenities.
Please note: camping with / in your vehicle at Lost Paradise is only permitted in the Sleep-In-Vehicle section, for those who pre-purchase a Sleep-In-Vehicle Pass (purchased separately from your event ticket and available from September).
