You can only sleep in, above or beside your vehicle at Lost Paradise in the Sleep-In-Vehicle section of the campgrounds.
Entry to this section requires the pre-purchase of a Sleep-In-Vehicle Pass (on sale in September). Sleeping in or around your vehicle in the GA car park is strictly prohibited.
This is due to the unique natural setting of LP, located inside a valley with a limited amount of space. In order to fit everyone in comfortably, we require the majority of attendees to carpool to the site and then camp separately from their vehicle.
