Marin County, CA

Moderate

The fog capital of the Bay Area. Marine layer rolls in from the Pacific almost daily in summer, shrouding the dramatic headlands in thick mist. The lighthouse trail offers surreal views when fog breaks.

Mill Valley, CA

Easy

Visibility
High fog

Hike above the fog layer for a stunning inversion view — a sea of white stretching to the horizon with the Bay Bridge and city skyline poking through. The summit is often clear while the valleys below are socked in.

Lost Coast Trail

Humboldt County, CA

Strenuous
24.6 mi3,200 ftApril–June

Prairie Creek Redwoods

Prairie Creek Redwoods

Del Norte County, CA

Easy
4.1 mi280 ftOctober–February

High fog

Fern Canyon and the surrounding old-growth forest are perpetually draped in mist. Roosevelt elk wander through fog-filled meadows at dawn, and the 50-foot fern walls of the canyon drip with moisture year-round.

Tomales Point Trail

Tomales Point Trail

Marin County, CA

Moderate
9.4 mi560 ftJuly–October
Visibility
High fog

A narrow peninsula jutting into Tomales Bay, this trail is flanked by fog on both sides in summer. Tule elk herds roam the bluffs, often appearing as ghostly silhouettes through the marine layer.

Hiking in fog — stay safe

Navigation

Download offline maps before you go. Fog can make trail markers invisible and GPS signal unreliable in dense tree cover.

Layering

Coastal fog can drop temperatures 15–25°F. Bring a waterproof shell even on warm days — moisture saturates clothing quickly.

Timing

Marine layer typically peaks at dawn and burns off by midday. Plan your turnaround before visibility drops at dusk.
