The archaeological site itself is truly impressive and well worth visiting; the problem lies with the tour guide.
During the tour, you are required to follow the guide. However, perhaps because it was peak tourist season in August, the guide seemed more like a temporary employee. Her English was fluent, but somewhat unclear, as if she had simply memorized a script. She couldn't understand questions asked in English, and didn't seem to have a deep understanding of the site's history.
Her presentation consisted of a few photocopied pictures, and with so many people spread out, it was difficult to hear her. Furthermore, she didn't allow enough time to properly explore and appreciate the site.
Even worse, when we wanted to stop for a few minutes to observe and take photos, she rudely refused and abruptly closed the gate (there were no other groups, so there was no issue of overcrowding). She ignored our questions, even when we told her that another family from our group was still behind us, slowly walking along. She offered no response and showed no enthusiasm or passion for the culture.
There were many tourists from various countries.
It's fair to say that visiting guided tours is a bit of a gamble. During our travels in Sardinia, we visited countless sites and met many enthusiastic tour guides who were passionate about history and culture; we learned so much from them and left with a wealth of knowledge and wonderful memories.
However, for this particular tour, had we not done some research beforehand, paying for the guided tour would have been a waste of money and we would have been disappointed.
