There are a couple of lots they setup for the event....kind of out in a field. Call it a decent 20-30 min walk to the entrance of the event, but most everything is. Can't remember what it cost. The biggest obstacle was getting out of the lot afterward......took FOREVER!
Tons of useful info on the Bottlerock site: https://www.bottlerocknapavalley.com/info/#parking-transportation Residents who live near the festival open up their homes for parking but the price is ridiculous.
Lots of free shuttles. Parking is $20-30.
