We had been before but hadn't climbed the steps. The view and the history is fascinating even if you choose to stay at the bottom but it really comes to life if you do decide to go up there. It is pretty steep and narrow but there are several stopping 'rooms' on the way. You might choose to go up just a bit if you'd rather not go all the way. There are a few windows on the way up. Getting to the top is worth it though. The day we went it was very windy so we just poked our heads out the door and didn't walk round the platform. I'm not that good with heights anyway. An added bonus for us was being there with a former lighthouse keepers granddaughter so she told us how it was to actually live there and have to bring lunch up to him when she was a little girl! We were there with relatively few other tourists around so there was no waiting and no crowds. It may be hard to cope with if there are people trying to come down the steps as well as going up! Having passed on it before and now I've actually done it, do give it a try. You will be amazed at the view and feel very proud of yourself for having made it!
