Where do you park your car when taking the ferry from the peninsula to the island (assuming you do not want to take your car to the island)?

You can park in the pier parking lot or the lot near the ferry entrance

I confirme. Plenty of parking on this island

There is a lot of parking on the peninsula. There is a pay lot near the ferry. There is very little parking on the island.

It would be cheaper to take your car. There's always parking (somehow) on the island.

You can park o on the main street and pay on the machine or there is limited parking on Balboa pier and walk to the fun zone
