The hook
The largest state park in Northern California, 87,000 acres of empty ridgelines an hour from San Jose, and almost nobody goes.
01Why it's worth it
Coe is the Bay Area's big, hard, quiet backcountry. It sprawls across the Diablo Range east of Morgan Hill in endless folds of oak savanna, manzanita, and pine, laced with ponds and creeks and trails that climb straight up the hills because the old ranchers never bothered with switchbacks. That's its reputation among locals who love it: brutal, beautiful, and gloriously empty, the place you train on before the Sierra rather than after. In spring the hills go electric green and the wildflowers come in properly, and you can walk for hours without seeing another person. The tradeoffs are real and worth respecting: the climbs are relentless, the sun is unshaded, water is scarce in the backcountry, and ticks are serious business off-trail. Go in for a lung-busting day hike from headquarters, or load a pack and disappear for a couple of nights.
02How to experience it
The main entrance is at Coe headquarters at the top of East Dunne Avenue, a long, winding climb up from Morgan Hill (about 1h20m from SF, less from the Peninsula). There's a small visitor center, a campground near the entrance, and trailheads straight into the interior. Spring and fall are the seasons; summer is punishingly hot and dry. Carry far more water than feels necessary, check for ticks, and get a backcountry permit at HQ if you're staying out overnight. Come for the emptiness, not for amenities.
