I spent 4 days in Spain, visiting Salamanca and Segovia, at the end of January, as solo female traveler (aged 50). It was a beautiful trip, both cities are breathing history, they have wonderful architecture, plenty of surprising sites to discover, delightful food and nice people.
I am not speaking Spanish (although I understand about 80% of the written language and about 60% of the spoken one); however my Italian was useful more than the English and I did not have any problems with finding my way around. And to answer a question asked many times on forums, linked to the solo female travelers, I found both cities very safe, with no areas to be avoided, pleasant to walk from early morning to late at night.
So, as a conclusion, I think both Salamaca and Segovia are absolutely worth a visit, with overnight stay, and should be on the “must see” list of anyone interested in cultural sites.
Writing this report is my way of thanking everyone that I met during my trip: personnel in the hotels and restaurants, museum custodians and people on the street that did their best to help me. I will split it in different posts for each day, in order to make it more manageable: there are many experiences to share, so I tend to make it (too) long. And if I make some mistakes, I do apologize but I am not a native English speaker.
