In addition to the Kyoto Animation offices the Lucky Star gang visited some famous tourist attractions in both Kyoto and Nara in episode 21. I visited some of the same locations so here's some pictures.

One of the signs you see at Kyoto station if you take the shinkansen.

Inside Kyoto station.
Tōdai-ji - Nara
The first tourist attraction shown.
Image from Episode 21 - 09m46s
This is the Buddha statue from the episode. It's not golden though.
There are golden Buddha statues here, but they don't have options as Konata called them. ^_^
Nara Park - Nara
Image from Episode 21 - 10m05s
Nara Park is of course well-known for the sika deer.
Image from Episode 21 - 10m09s
I actually saw this deer with a bad left eye. It didn't attack me like the one Tsukasa met though.
Kōfuku-ji - Nara
Image from Episode 21 - 10m29s
This is the place where the guys from India asked Tsukasa to take a picture of them.
Image from Episode 21 - 10m44s
The pagoda is the same of course.
Image from Episode 21 - 11m07s
Same with the octagon hall here.
Kiyomizu-dera - Kyoto
Image from Episode 21 - 12m27s
This temple is famous for its wooden stage seen in this picture.
Image from Episode 21 - 12m30s
The grounds below the wooden stage.
Image from Episode 21 - 12m31s
The view of Kyoto from the wooden stage. Wasn't clear enough to see the mountains unfortunately.
Image from Episode 21 - 12m34s
Okunoin hall was being renovated when I visited, but you can still recognize the roof if you look closely at the image.
Image from Episode 21 - 12m15s
I didn't get a shot of the metal staff they tried to lift, but you can see this statue in the background.
Ginkaku-ji - Kyoto
Image from Episode 21 - 14m57s
Ginkaku-ji. Even with the name it's not silver as they also commented on in the episode.
Image from Episode 21 - 15m20s
The fence and the rest of the background matches pretty good.
No map since all of these are famous tourist attractions.
These locations were visited on 2014/04/09 and 2014/04/10. The Kyoto Station pictures are from 2014/04/06 and 2014/04/12.
