This is just from a non-practioners perspective, but if a nice, quiet area is what you want, here's a few recommendations.
Check out your local bus routes. Some of them will take you absolutely miles out of town for a cheap price. Throw on your earphones, watch the scenery go by and then have your spiritual time away from all the hustle and bustle. You might have to put up with a bus trip back, but you'll be able to approach it from a better perspective. One of those times where it really is the journey that counts.....
If you're in a dorm, grab an early sleep and wake up around 1am. There's a reason why some modern day wiccans are up around the witching hours. It has nothing to do with rituals or beliefs. It's so they can finally get some peace and quiet.
Start a mini-indoor/window-garden at your apartment/dorm. Not pot-plants, just a raised garden bed (you can get a 5'x18" one for cheap, even if it is plastic). Throw a couple of leafy plants in and some flowering plants/shrubs. It will give you a nice area that you can clear your mind more easily and feel a little more connected with nature, regardless of the amount of concrete views you have. Plus, flowers give a strange feeling of accomplishment when they bloom.
Set up a bird feeder at a window. They might crap everywhere, they might get a bit annoying, they might even be considered flying rodents in some areas, but even a flock of pidgeons can make you feel more connected to the beauty of the world. It depends on where you live, but a bird feeder can get you all kinds of wonderful natural sights, right at your down-town window. I get lorikeets, honey-eaters, magpies, crows, eagles, pheasants and flying foxes at mine. Not a bad mix really.
There's plenty of ways to get into the vibe for some wicca. If its the big-city disconnect that's bothering you, go to nature or bring it to you.
