I think the most unusual climb we have had was at New Point Loma, CA . This lighthouse is not very easy to get access to climb the tower since it is on an active Coast Guard station. It has a beautiful view over the Pacific Ocean from the top of the tower.
The Point Loma light will never be climbed again (unless someone finds some cash to do major repairs). Not even the coasties who look after it are allowed up the tower these days! We went in March to see it
I wrote about it ... The first lighthouse I climbed was
The Lizzard Lighthouse on the south coast of England.
I can't decide which was the most impressive. Warnemünde on the German Baltic Coast which is a handsome tower with enthusiastic people, the Kiel lighthouse, which is very modern or maybe Point Fermin, CA which has had very impressive restaurtion
They are all impressive in different ways.
