Yes .. Staffa is quite fascinating, the rock structure is quite something to see, I was a kid when I was there many moons ago, we landed against a small pier a bit away from the cave... which was easier said than done, as there was quite a swell on at the time I remember, and we heaved up and down a fair bit.. short walk to the cave, and as you enter on the RHS, there was a walk way inside it with a metal balustrade to let you walk right inside. This rock structure can be seen as far south as Ailsa Craig on its south side in Scotland, but Staffa has the most striking example of it IMO
