- Intl tip
- Northern California's LARGEST state park (87,000 acres, Diablo Range east of Morgan Hill) — a vast, wild backcountry of steep ranch roads notorious for relentless, leg-breaking climbs. Genuine remoteness near Silicon Valley. Spring (green, wildflowers) and fall only — summer heat is savage, water scarce. EXPERT terrain: brutal climbs, navigation, self-sufficiency; ticks, rattlesnakes, poison oak. Backcountry camps make it a superb rugged bikepacking objective. Humbling and untamed.
