Best destination in Spain?

Only been there once.. only for 6 days..and we LOVED Tossa De Mar.. lovely small village on the sea on the Costa Brava coastline. No Starbucks, no McDonalds.. many small restos and cafes.. beautiful little beach and cove, and on the hill on one side the remains ( well maintained ) 13th century ramparts/fort.. Google for pictures.. they are so true..

Planning to return to Spain for 10 days this summer and really struggling on where to go.. Tossa was amazing, but small,, and we really want to find another place similar to explore.. So hard. seems like alot of coastline has mostly larger towns and cities with sky scraper hotels and resorts.. not our style.

Did get some great ideas on this forum a few weeks ago but still open for more,, Nerja? Girona? Want to be on coast.

What about Majorrca? Small town , not main city on island.

Look at somewhere in Cantabria....Santander, a rather large city for the area is nice, as well as the sea coast villages north and south. The area around the Caves at Altamira, Santillana del Mar is designated as one of the most well preserved towns in Spain. Google Sanatander of Cantabria and see what is offered. I have visited and found it a desired destination.

I love Andalucia - Sevilla, Cordoba, Granada - but summer is a tough time to visit there because of the heat. Much better in either April and May or late September and October. I am going north this October to see Leon, Burgos, Pamplona and Zaragoza.

I love Asturias, on the northern coast. So much it is public land, and it is mountainous and green. Lots of hiking, parks, historical sites, and great villages to explore, plus pretty seacoast and beaches.

I absolutely love the small towns in Andalucia. My favorites are Vejer de la Frontera, Ronda, and Carmona. Carmona can easily be seen as a day trip from Sevilla. Rick always recommends Arcos de la Frontera which is great too.
I would also recommend going places that most people go for only a day trip and then actually staying the night, for example Ronda and then Toledo in Castilla La Mancha. Toledo is very mysterious at night. There aren't any cars allowed in the historic area, so you can almost feel like you're stepping back in time as you wander the dark, mysterious alleys.
Spain has so many wonderful places, this is just a small sampling. I'm sure the other respondents have great suggestions too.

I have been to Spain many times. It is so difficult to pick a single favorite spot because the country is truly beautiful and amazing. That is why I keep going back. One area, often not on the tourist radar, is Extremadura. I was fascinated with Trujillo, Cáceres, Mérida and Guadalupe. Look into these towns next time you are planning a trip to Spain.

Madrid is my favorite because of several nonstop flights from New York, tapas, variety of wines, I know a few Spanish words & understand their Castellano, Prado & Thyssen museums, convenient metro, affordable frequent connections by bus train or air to other towns and cities, temperate climate which can be chilly in late Fall.
