Coastal road and hill cycling with broad seasonal planning coverage.
Planning brief
Base yourself around Santa Barbara or San Luis Obispo. The guide currently covers 53 route ideas across 4 riding styles, with the strongest fit in Road.
Distances, climbing, costs and seasonality can change. Confirm the exact route, legal access, weather, transport and accommodation with current local sources.
Derived from each route's recorded surface, not from a bike review.
Every planner route here is graded Confident or Expert. Newer riders should treat this destination as a stretch, or pick a gentler base.
The archived BRouter files contain elevation values from a layer that is not cleared for commercial publication. The repair is to preserve the OSM-routed geometry, replace every elevation sample with NASADEM data, recalculate ascent and timing, and publish only after automated provenance and regression checks pass.
