Maxwell Farms Regional Park is a 0.7 mile moderately trafficked loop trail located near Sonoma, California that features beautiful wild flowers and is good for all skill levels. The trail offers a number of activity options and is accessible year-round.
Calling this a trail is overly generous... A barely-contiguous path around a man-made park is more like it. Good enough for doing exercise laps (I did a few times to time against myself), or perhaps taking the dog for a walk... but don't expect breathtaking vistas. Rather some parking lots, some suburban grass... and some human detritus.
