It's a forested world - sidewalks would be totally out of character. You need to slow down and watch how the enemies are moving before trying to get by. Actually, Wizard City and Dragonspyre are the only worlds WITH sidewalks, so it's really not unusual.
Under the tab to the left "See the Game", visit Grizzelheim. It says:
"Inspired by Norse mythology, Grizzleheim is an airy, outdoor landscape of snowy mountains, glacial ridges and towering trees that is home to three new Wizard101 tribes - Bears, Wolves and Ravens.
Players will first encounter the Viking Bears of Grizzleheim, great traders with the ability to travel the worlds of the Spiral, in the free-to-play areas of Wizard City. "
It's really kind of easy to stay away from the enemies. Just slow down, and watch their patterns. I like GH with it wooded paths, and trees, and mountains. :D
