Loma Mar exhales a scent of damp earth and redwood needles, a pervasive perfume carried on the cool, coastal air. It lies 13.3 miles south-west of Los Altos, CA (from Los Altos, CA: bearing 234°T), and is situated 8.8 miles south-south-west of Portola Valley. Here, the Santa Cruz Mountains plunge towards the Pacific, their slopes cloaked in a dense, emerald tapestry of ancient forests that filter the sunlight into shifting patterns on the winding roads. Narrow creeks, swollen with recent rains, tumble and whisper over moss-slicked stones, their water a clear, cold invitation to the sea. The terrain itself is a study in dramatic contrasts, from the shadowed depths of the redwood groves to the sun-drenched clearings that offer fleeting glimpses of the distant, blue horizon. The history of Loma Mar is as deeply rooted as the colossal trees that define its landscape. Once a place of rugged logging camps and scattered homesteads, its economy now leans more towards a quiet stewardship of the land, with a focus on nature preserves and the gentle hum of small, independent businesses. The annual migration of the monarch butterflies, a breathtaking spectacle of fluttering orange and black wings, draws visitors to the nearby sanctuaries, a vibrant testament to the enduring wildness of this corner of San Mateo County. The pace of life in Loma Mar is measured, dictated by the rhythm of the seasons and the slow, deliberate growth of its magnificent trees, fostering a sense of timelessness that permeates the very air.
