I am in the early stages of planning a 7(ish) day tour around the area of Cadiz. I have not decided yet if I will fly into Jerez (limited airlines) or Seville. I want to only use public transport (bus / train) and I am thinking of doing a circular tour for example starting in Seville then onto Sanlucar de Barrameda, Jerez, Cadiz, Vejer de la Frontera, Medina Sidonia, Arcos, Seville (something like that). I am a solo traveller looking really to see sights, enjoy the architecure and scenary, good food, sights etc. I will be travelling light, no suitcases.
Regards to places like Medina Sidonia, is it better to go here for the day from Cadiz rather than stay over for the night or do you think there is enough to see in the other locations outside of Cadiz / Seville to justify a nights stay in these locations?
Can you also get a bus or rail pass that allows open travel for a week / month or is it all based per journey? I can't see that there is a bus route to Sanlucar de Barrameda, but again, I am in the very early stages of planning.
Thanks advance for any help that can be provided.
