Doesn't sound too German, does it? That's where I went on Sunday for a nice bike ride. It's called the Walhalla temple and is the German hall of fame and was modelled on the Parthenon in Athens. Regensburg is along the Danube and there's a nice bike trail and Walhalla is about 10-15 km east of town along the bike path.
The bike trail actually stretches all the way to Budapest and goes past Vienna as well. Sometime in the future, I'd love to go all the way but it's a bit too cold right now to go biking for too long. Also, an old mountain bike wouldn't be the best thing to take all the way. Saw a lot of other serious bikers along the way. Getting out of town was a bit of a hassle as following the various bike lanes was almost like driving on a highway and taking diferent exits. Thankfully, I didn't get a ticket for biking in the wrong lane!
Got a bit lost initially before asking for directions a couple of times. The nice thing about living in a small town (by Bavarian standards Regensburg is not small though) is that within 10 minutes one is out of the city and out biking in fairly rural areas. The weather was nice in the afternoon and biking along the Danube past picturesque German villages was fun. It was a Sunday so a lot of people were out on the bike trail and the parallel walking path.
The walk up to the temple wasn't too long and once you're on top of the hill, there are some great views of the Danube valley. It's a nice place to spend half the day soaking in the sun, reading a book and chatting with other visitors. Though on a sunday, it was a bit too crowded at times with some tour groups. The inside wasn't as impressive as it looks from far away. It's full of busts and statues of famous Germans. The view was nice though.
Maybe it's a Bavarian thing but even the maths department here is full of portraits of famous German mathematicians all along the corridors. It's slightly intimidating walking out of a room and seeing Gauss staring at you.
