We are booked on the RS Best of Spain Tour in 14 Days for Spring 2019. Among other stops, the tour spends 1 night in Ronda, and 2 nights in Arcos. There are of course many beautiful "white villages" to explore in this region. After the tour we have some time and would like to come back to this region for 3-4 days before heading home. Which town in this region would serve as the best home base? Rick has written an article about this region: (https://www.ricksteves.com/watch-read-listen/read/articles/andalucias-white-hill-towns) where he mentions the following towns as noteworthy: Arcos, Zahara, Grazalema, and Estepa. Other searches reveal other recommendations such as Mijas, Casares, Ronda, Frigiliana, and Comares. I realize we won't see all these places in 3-4 days, however, my question is, which of the towns I've mentioned here would serve as the best home base from which to take day trips to explore the area given that some of the towns are already stops on the Rick Steves Tour? We plan to rent a car after the tour and explore this area, but would like a good home base, and at present, I don't know very much about this area at all, other than what I've read in a few short online articles. We could fly out of either Seville or Malaga for our return.
Thanks - I appreciate any and all suggestions! Gord
