We had a short stop at Geysir and Gullfoss and there have been some major changes to these places. Barriers and fences have been a quite unusual sight in Iceland, if you fall from a cliff, it is your problem..... But with the increased number of tourists, which are definitly not only outdoorsy people, the big places have to be managed differently. It is maybe not nice for us photographers, but it is understandable. During our last workshop we had been at the Black Beach of Vik when a tourist was caught by a wave and was never seen again.
At Geysir there are only a few more fences, but at Gullfoss the lower platform and its footpath boasts new fences and can be closed with a solid gate. I am sure that during winter we cannot reach the lower platform! Rangers are patrolling, the stairs have been widened, the visitor center is expanding and the visitors stood three rows deep at the major viewpoints. You had to cue! It all depended on the number of busses arriving.
All the same, Gullfoss is still an awesome place!
