The geocache is not at the posted coordinates but within easy walking distance.
As you can tell by the title, this is the Bonus cache for "Ojai Trolley - West Loop" Adventure Lab, https://adventurelab.page.link/3Y8t
You do not need to do the AL to find this geocache. If you read the AL descriptions, you'll find the coordinates. You are looking for a small plastic container magnetized so it doesn't flow to the ocean.
