I don't even want to know how this feels in the summer but in September it was very crowded. The pathways are tiny and a lot of people are trying to stick to their tour guide and don't get to see much or take pictures, everyone is somehow in a hurry... Awful experience.
The place, on the other hand, is amazing. But people ruin it. I would love to go there again sometime when there won't be so many many tourists.
