Season

Water

Hazards

Long paddle, open-ocean swell, reef shallows, shipping-channel marker, abrupt energy loss in shallow water and solo-shuttle exposure.

“A local reply calls Mushroom Rock the Bay Area's best workable prone-foil option under limited wind and small conditions, while warning of a roughly quarter-mile paddle. Community/area pin only; exact break, access and etiquette must be verified. Requested-field batch 04 verified 2026-08-01: guide/resource labels and hazards use cited row evidence; exact, nearby and route-endpoint relationships are explicit; unresolved fields remain Unknown. Progression Project forum first-hand log documents more than 60 Mushroom Rock-to-Miramar no-wind downwind laps using refracted Pillar Point swell and a self-supported bike/scooter shuttle.”
