Blow hole

Me and Gabi went for a drive up to Eshaness today and parked up at the lighthouse. This is a 'blowhole' in the rock, quite a good distance back from the cliff face. It is not more than 2 metres wide at any point, but it goes down vertically about 40 metres to the sea below. You can stand at the top and watch the waves coming out and in at the bottom, and the noise echoes up the chamber.
I am sure that many poeple who visit the lighthouse never get to see it, because it is not marked or signposted and you cant see it until you get right on top of it.
