The lighthouse at the mouth of the Holland channel is on more Michigan postcards than any other structure, and visitors routinely fail to work out how to get to it.
Start with what it is. A light has stood on this site since 1870. The present building took shape in 1907 as a fog signal station painted a dull manila colour, gained its light tower in 1936 — which brought it to 49 feet — and was not painted the red it is famous for until 1956. So the thing you photograph is a twentieth-century building with a nineteenth-century job.
Now the access problem. Big Red sits on the south side of the channel, reached by a private road through a residential area, and it is not open for casual walk-up visits. Occasional open days are run by the preservation group that maintains it; those are announced and ticketed.
What everyone actually does is view it from the north side. Holland State Park's beach at the end of Ottawa Beach Road looks straight across the channel at it, and that is the standard photograph — red building, pier, water, and the dune behind. The park is a Michigan state park, so a Recreation Passport is needed on the vehicle.
Best light is late afternoon and evening, when the sun is behind you and on the building. In winter the same view comes with ice shelves on the channel, which is better.
