About 90 percent of the area burned in a 2007 fire, but the 4,300 acres of oak woodland canyons and grassland hills in Trabuco Canyon are recovering nicely with flowers like phacelia, lupines, mariposa lily, canyon pea, and wild rose blooming from about March through May. Bonus: stunning rock formations along Red Rock Trail (4.5-mile round-trip).
