Tahoe City Bike Paths is a 21.4 mile out and back trail located near Homewood, CA and is good for all skill levels. The trail is primarily used for mountain biking and is accessible from March until November.
Enjoyed this ride when I was a Truckee resident. Used to ride it couple times a week for training, from Tahoe City into Truckee.
Tip: don't recommend biking this in the month of November, unless you are packing some heavier gear to keep warm. I made that mistake once... was quite a bit warmer near Lake Tahoe and got colder as I neared Truckee. Burrr!
We have enjoyed this scenic path following the contours of the Truckee River on several occassions. Great spots along the way for picnicing, swimming, wildlife, wildflowers. Family friendly.
