There are about 35 miles of paved trail with only 2 or 3 level road crossings. It goes along the American river. One frequently sees deer, turkeys, coyotes, jack rabbits and even snakes. There are also lots of birds and, in season, salmon swim up stream. Most runner and walkers are good and stay to the correct side. It is hard to believe there is this much tranquility and nature right through the city.
