Milagra Ridge

In a word, this hike is a breeze.

The strong winds that sweep Milagra Ridge will test your hat, your balance, and sometimes even your ability to hold a conversation with your fellow hikers. Pacifica locals will tell you that this is par for the course on their fog-kissed coast: some days you’re peering into a gray mist, other days the curtain parts and the view stretches endlessly from Mount Tamalpais in the north to Montara Mountain in the south, with the Pacific Ocean rolling out like a blue-green carpet at your feet.

Milagra Ridge is one of the smaller Golden Gate National Recreation Area units-just 275 acres-but feels much bigger thanks to its openness and sweeping vistas. Ironically, the ridge itself is not quite as tall as it once was. In the 1950s, during the height of the Cold War, the military leveled the summit to install a Nike missile site. From here, San Francisco was “defended” by a battery of surface-to-air missiles, ready to launch in case enemy bombers dared approach. Today, the relics of that military era lie buried beneath the grassland. The only thing launched skyward now are the hawks, kites, and turkey vultures riding the ridge’s steady updrafts.

Even stranger than missiles are Milagra’s most delicate residents: butterflies. This windswept, often inhospitable hilltop is prime habitat for the rare Mission Blue and San Bruno Elfin butterflies, two species that cling to existence only here, on neighboring Sweeney Ridge, and on the flanks of San Bruno Mountain. It’s a mystery of natural history-how something so fragile can persist in a place so blustery. Yet here they are, fluttering between patches of lupine and buckwheat. The ridge also shelters endangered plants like the San Francisco wallflower and coast rockcrest, which find a precarious foothold in the coastal terrace prairie.

Because of these fragile habitats, some old paths have been closed or fenced to aid recovery, and rangers ask hikers to stay on marked trails. The tradeoff is more than worth it: you get both a short, bracing hike and the satisfaction of walking through a rare ecological island, right at the doorstep of suburbia.

Approach Milagra from the top via College Drive or from below via the Milagra Battery Trail. Either way, you’ll earn your windblown hair and sweeping views. And perhaps, if you’re lucky, a glimpse of those resilient butterflies dancing in the gale.
