Garcia Wilderness
Garcia Wilderness preserves the long east-west ridge of Garcia Mountain and separates the Santa Lucia and Machesna Mountain Wildernesses. Here you'll find rugged, chaparral-covered slopes and oak woodlands highlighted by meadows, grasslands, and lush creekside vegetation. A remarkable diversity of plant and animal life populates the area, and spring reveals a vibrant display of wildflowers. The Caldwell Mesa Trail offers 11 miles of varied terrain, from quiet meadows to steep, rocky slopes. The Sellars Potrero Trail branches off from Caldwell Mesa and travels five miles east to the boundary near the Salinas River. The Avenales Trail meanders four miles from Stoney Creek northeast over Garcia Mountain to the Salinas River.
