Although most area residents (and Google Maps) consider the Lake Natoma Trail part of the American River Bike Trail, it is a separate trail in its own right.
The Lake Natoma Trail dips and dives over many small rises along the southeast side of its namesake lake, curving through large piles of river rock left over from dredging many years ago. You'll find plenty of wildlife, as well as delicious shade from summer's hot weather. Fall's leaves blanket the trail, and winter's rains bring spring's shockingly green grass.
The trail crosses Willow Creek and Alder Creek on wooden-decked bridges, also providing bike and pedestrian access to Folsom Lake State Recreation Area's Willow Creek and Nimbus Flats boat launch areas.
You can park at several small parking lots along Leidesdorff Street, as well as in the parking garage at the corner of Leidesdorff and Reading Streets. It is a short walk down Gold Lake Drive to the beginning of the trail below Lake Natoma Inn, although many prefer to meet the trail from a feeder path starting at the east edge of the north park-and-ride lot on Leidesdorff Street.
You can also join the trail at Willow Creek (vehicle fee to enter) or Nimbus Flats (vehicle fee) or from the Iron Point light rail station (cross Folsom Boulevard to the feeder path and travel either northeast or southwest to join the trail proper).
