Spot Guide › United States › California › King Rock FoilDrive wave reef
California, United States · 37.4938, -122.5025
Season
March 6, 2024 session documented; no recurring season established
Water
Offshore reef waves around 4–7 ft in the documented session, crumbling and fading into open ocean/bay
Experience
Advanced assisted-foil rider with Pillar Point reef, harbor and motor-rule knowledge
Hazards
Offshore reef, harbor entrance and vessel traffic, cold water, open-ocean exposure, assist failure, motorized-craft restrictions and unpublished reef depth/current. The forum discussion warns that efoil/FoilDrive legality was under active scrutiny.
Parking & access
The rider came through Pillar Point Harbor mouth, but the forum does not establish a legal powered-foil launch, marina access, parking, battery stop or return lane. Verify current harbor and sanctuary rules.
“A Progression Project forum eyewitness report documents a FoilDrive rider powering from Pillar Point Harbor mouth to King Rock and riding roughly 4–7 ft crumbling waves that faded into open ocean/bay. The attached forum session image labels King Rock and shows an offshore track, but not a legal launch or surveyed reef boundary.”
