Photo suggestions for upcoming tour of Spain?

Being part of a tour will restrict the amount of time you have wander to out of the way places. In Sevilla, while very popular, the Plaza de Espana is nice. On the opposite bank of the river, across the San Telmo bridge, one can get a nice view of the Torre de Oro and cathedral/Giralda. In Toledo, I enjoy the Puente of San Martin, puente de Alcantara, and the mirador to see the same view that El Greco painted in his painting “A view of Toledo.” There’s also Mariano Zamorano swordsmith if swords are being made while you’re there. Off a side street near the cathedral is El Pozo Amargo (bitter well). It provides a quick photo op. There are legends that surround both the bridge of San Martin and the bitter well. In Segovia, it’s hard to get enough photos of the aqueduct from multiple angles and vantage points. Outside of town is the Mirador de la Pradera de San Marcos. It provides a nice view of the Alcazar. Often, it’s nice to revisit the sights at night after the crowds have thinned.

I'll need to go back to photos but sometimes the best photos are when you look up or down. Toledo has Jewish tiles in the sidewalks. If you can get to the stairs at the top of Segovia's aquaduct it offers a different perspective. I took photos of the vultures riding the thermals there. The Botanical gardens bet to the Prado in Madrid. The Seville fortress gardens. Though we'll photographed, the old Exhibition grounds in Seville. When I was there someone was making huge bubbles which added an interesting perspective. The whole place is great for angles. Then there is the town on the opposite shore.

In Barcelona:

Parque del Laberinto de Horta: A 18th-century neoclassical garden on a former palatial estate. It's not very well known with tourists so you will probably have a more private photography session. It's very beautiful with numerous sculptures of Greco-Roman mythology along with a number of fountains, springs, and pools. In the center of the gardens is an English style hedge maze.

Hospital de Sant Pau: A Gaudi-esque modernisme complex built in the early 20th century as a hospital. It's about a 10 minute walk north of La Sagrada Familia. It's now a museum and has been named a UNESCO World Heritage Site. Sant Pau has significantly less tourists than La Sagrada Familia.

Montjuic Fortress: A large 17th century military fortress on top of Montjuïc hill, which overlooks Barcelona. The fortress has some of the best views of the Barcelona cityscape around.

I had a lot of extra time to consider this question on my snowy, slow bus commute home today, and as mentioned, on a tour, you might be limited to time you can get away. Why not think about the angles you take the shots of. I don't know what level of photographer you are, or your equipment. I use a bridge camera or a point and shoot with a good zoom. My favourite photo of the Eiffel Tower is just a part of a leg. It shows enough of the curve that everyone recognizes it, but it also focuses on the immensity of it and the engineering and building feat it was at the time. I printed it in Sepia.
The Alhambra at night is wonderful. The lighting shows the depths of the plaster work so much more than in the day time.
The Hospital de a Caridad in Seville is quiet and less visited.

The Museum of the Visagoths in Toledo has a tower for a bird's eye view of the city.
Read a more in depth travel guide than Ricks - something like Lonely Planet for lesser visited places
Barcelona has hundreds of 'Modernista' buildings around, so keep an eye out for an architectural feature of interest
Photograph what moves you rather than what is 'iconic'.

Thank you for all your tips. Just the sort of places where I like to make photos. I expect I will be heading out early in the morning for some good light and a bit more quiet. I look forward to evening light too, but that's when I plan to do some street photography. I love to find unusual places to photograph (I eagerly follow Rick Steve's advice to get lost). If you think of any other places I so appreciate your sharing them with me.

We don't take a camera so these are more on what I recall as interesting views though they are probably customary spots:

• in Barcelona from Park Guell you look down across the city, with the sea beyond and hills to the side. I don't recall, but I guess you get a similar view, but from higher if you go up Tibidabo. Also the area around what I think is called Placa de les Glories (Carlos or Enric will know better) has some v. interesting structures with buildings at unusual angles or shapes

• in Granada, the S Nicolas viewpoint is justly famous for looking across the valley to the Alhambra. But if you walk a bit further East in the Albaicin there is another mirador called La Lona where you see the tip of the Alhambra (the castle part), the city spread below you and the mountains in the distance.

• in Seville consider visiting the Metropol Parasol (aka the mushrooms), a rare example of modern architecture which isn't irredeemably ugly and you can walk around the wooden roof for 360° views of the city.

Edit - with Guell you'd be looking South East, so straight into the sun in the morning. Whilst I don't photograph, I guess that might matter?

In Granada, I like the San Nicholas viewpoint, but I also thought the views from Sacramonte of the Alhambra were pretty spectacular and its less busy. In Madrid, I got some lovely pictures around the royal palace at night. In Barcelona, I got some nice photos in the Bouqueria. I love to photograph fruits, veggies, etc. In Segovia, I got beautiful pics of the countryside from the Alcazar. In Sevilla, I got great pics at the plaza de espana and in various places in the Jewish quarter between the cathedral and the alcazar. When I travel, I do a lot of walking. I'll start with a walking tour (like a RS) in the city and expand from there.

There are really lovely, unique, "peek-a-boo" views of the Alhambra as you wander around the Albaicin section of Granada. I have a blowup of a shot that I took from somewhere in the Albaicin showing orange trees and lilac bushes in the foreground, then looking over the rooftops of Albaicin buildings, and further back the Alcazaba towers, and behind it all, the Sierra Nevada, still with snow.

There are similar shots in Toledo as you walk through the narrow streets. Look up to see what peeks over the close-up stuff. Lots of really nice views framed by the buildings -- the architectural detail is amazing. The cloisters of the Monastario de San Juan de los Reyes also have some great photo opportunities (love the gargoyle downspouts).

If you get a chance to stop along the way between cities, keep an eye out for windmills and olive groves. I love my photos of the countryside.

In Cordoba, there is a place close to the Mezquita where you can get a pretty shot of a narrow street filled with flower pots and the Mezquita tower in the background. Calleja de las Flores. I think I found it in the RS guide. Otherwise, I'm sure you could ask in a hotel or maybe your tour guide would take you there. It can be crowded, but when we were there in November, people were pretty thoughtful about "taking turns"
