Welcome to Portland Head Light! First completed in 1791, this lighthouse is an iconic fixture of the Maine coastline. You can visit the museum inside the keeper's house, walk around the beautiful Fort Williams Park, find one of the other caches hidden here, or drop a quarter into the pay-for binoculars and see what you can see! Bonus points here if you can find one (or all) of the following: Fort Gorges, Ram Island Light, Spring Point Light, or maybe even Fort Scammel.
Now for the cache: You are looking for a magnetic micro, hidden near ankle level on the left side of the keeper's house. Happy hunting!
