Located in San Mateo County, California, Purissima is a ghost town. It sits roughly 6.8 km (4.2 mi) S of Half Moon Bay.

Purissima is a ghost town in southwestern San Mateo County, California, United States, near the junction of State Route 1 and Verde Road. Purísima means "purest" in Spanish and is most commonly used in Spanish to refer to La Purísima Concepción (the Immaculate Conception) of the Virgin Mary (note historical misspelling in English resulting in double "s", or the result of the Holstein pronunciation with use of the "ẝ" being mistaken as ß "ss", or perhaps spelling comes from the local Portuguese influence, where the spelling from A Puríssima Conceição would be correct). Purissima is the name of the town used as the setting for Ross Macdonald's 1958 crime fiction novel 'The Doomsters'.From the Wikipedia article “Purissima, California”, licensed under CC BY-SA 4.0.

Milky Way & night sky

From Purissima, the Milky Way core is visible in a dark sky from March through September. June gives the longest window (about 5.3 hours on a moonless night), and the core peaks around 24° above the southern horizon. Our light-pollution model puts the sky at about Bortle 5 (suburban sky), so expect visible sky glow; drive away from towns for better results.

Window when the galactic core is at least 10° high during astronomical darkness on the 15th of each month. Pick nights within a few days of the new moon. Plan exact nights with the Milky Way planner.

Estimated sky darkness: 5 Bortle 5 — Suburban sky. The Milky Way is weak near the horizon and washed out overhead; long exposures pick up a sky glow. Modeled zenith brightness ≈ 19.62 mag/arcsec².

Weather & best season

Long-term NASA satellite data for this area show October as the clearest month (about 44% average cloud cover) and December as the cloudiest (59%). September is the warmest month and January the coldest, which matters for gear, snow access and how long batteries last at night.

Photography tips for this ghost town

  • For interiors with windows, blend two exposures (one for inside, one for the view) instead of relying on HDR alone.
  • Old buildings under the Milky Way make strong night images in dark rural skies.
  • Look for details: door hinges, faded signs, square nails and window frames tell the story.
  • Leave everything as you found it; removing artifacts from public land is illegal.
  • Respect private property and closures: many ghost towns are on private land or protected historic sites — never enter unstable buildings.
  • Tell someone where you're going in remote areas and carry the ten essentials.

Season: High-elevation mining towns are reachable mostly from June to October; desert ghost towns are best in spring and autumn.

Suggested gear: Wide-angle lens, Tripod, Headlamp, Sturdy boots. Work out exposures with the depth of field, ND filter and NPF rule calculators.

Permits, drones & access

Private property: Many ghost towns sit on private land or protected historic sites. Respect signs, never enter unstable buildings and leave artifacts in place.
