Rover's Run

Bring your bike helmet and your bear pepper spray! According to the Alaska Fish and Game department, a “few dozen” brown bears roam the area around Rover’s Run, a popular mountain-biking trail in the outskirts of Anchorage. Indeed, a mauling this year and one in 2008—both nonfatal—have prompted local officials to consider shutting down the trail. It is a former game trail converted for biking and skiing use. Alaska Fish and Game says it “has long been a place where bears come down from the mountains and congregate for salmon heading upstream to spawn.”
