Unfortunately we have stopped offering free tours in English as from this year 2018. There were very rarely 5+ people interested in taking it so we decided to keep the free tours in Spanish.
Instead, we still offer private tours at very reasonable prices and with great acceptance amongst our customers. We customise tours, tailor-made for each and every one of our clients. To see the prices please follow the link: https://freetour-segovia.com/private-groups-and-visits-made-to-measure/
You will not be disappointed, please have a look at our reviews in tripadvisor, that is our best asset https://www.tripadvisor.es/Attraction_Review-g187494-d10532280-Reviews-Castellum_Free_Tours-Segovia_Province_of_Segovia_Castile_and_Leon.html
