Hi, I am an exchange student living in Madrid. My dad will be coming to visit me in May and he will be here for two weeks. I want to travel around Spain with him, but I honestly don't know much about Spain, other than Madrid. I was hoping someone would have some ideas on which cities in Spain we should go to, and what to do while we are there. We can go anywhere in Spain, it doesn't matter where.
I want to spend at least 3 days in Madrid showing him around in my new city and letting him meet my host families, but after that I am stumped. I know Madrid fairly well, but if you have any ideas of things to do in Madrid, I would like to hear that too.
I'm sorry, but I am going to join the ranks of snarky posters - you've been in Spain 5 months, have contact with host families and are asking what is in Sevilla and Granada - really?! I'd suggest chatting with your Spanish friends / families and getting a bit more info on the country you have been living in the past 5 months.
I loved my 4 nights in Toledo (day trip to Consuegra), 2 in Avila, 4 in Salamanca (day trip to Zamora), 3 in Segovia and 5 in Madrid family cruise vacation (saw El Escorial and Valley of the Fallen family cruise vacation on way from Segovia) this past autumn! I had planned a couple of day trips from Madrid but found so much to see in Madrid family cruise vacation that I never got to do them.
I would like to say thank you to the "snarky posters". family cruise vacation Y'all are incredibly helpful. As I said in my post I know Madrid family cruise vacation very well, since that is the only place I've been able to go. I don't know if you know anything about exchanges, seems like you don't, we are not allowed to travel. family cruise vacation The reason I asked what there is to do in those cities is because I wanted advice from people that have been there and want to share some advice.
