The place
About Trinidad Head
Trinidad Head is the 350-foot headland at the mouth of the bay, and the loop around it is the best land-based whale watching in the county. Gray whales pass close on their way north between March and June, then south again from September into January. Below, Green and Flatiron Rocks carry as many as 60,000 nesting common murres in spring and summer, along with pigeon guillemots, cormorants, storm-petrels and black oystercatchers.
Two things about this place are consistently misunderstood.
The first is the lighthouse. The one you can walk up to in town, take pictures of and read the memorial plaques at, is a 1949 replica built by the Trinidad Civic Club — though it does hold the original Fresnel lens and fog bell, and it was moved onto a new foundation in December 2023. The working 1871 Trinidad Head Light is out on the headland on a 13-acre BLM parcel, and it opens to the public on the first Saturday of the month, 10am to noon, with Trinidad Museum Society volunteers.
The second is who runs it. The City of Trinidad manages the loop trail; BLM manages only the lighthouse parcel, which came into the California Coastal National Monument in 2017. That's why no federal source publishes a trail mileage. Local sources put the loop at roughly 1.3 to 1.5 miles, and the first stretch is genuinely steep — a survey measured 14% grade for the opening fifth of a mile before it eases.
Franciscan fathers put a cross on the summit in June 1775 when Hezeta and Bodega anchored here, meeting the Yurok people of Tsurai, whose village stood above the bay.
Leash your dog. Never turn your back on the ocean.

Local planning questions
Frequently asked
How long is the Trinidad Head loop trail?
There's no official mileage — BLM doesn't publish one because the City of Trinidad manages the trail. The Trinidad Coastal Land Trust puts it at 1.3 miles; an accessibility survey measured 1.5. Either way it's a short walk with a steep opening climb.
Can you go inside the Trinidad Head Lighthouse?
Only on the first Saturday of each month, 10am to noon, when Trinidad Museum Society volunteers open it. The 1871 light is on the headland itself. The lighthouse down in town is a 1949 replica — freely visitable, and it holds the original Fresnel lens and fog bell.
When can you see whales from Trinidad Head?
Gray whales migrate north between March and June and south from September into January. The headland's height and position at the mouth of the bay make it one of the better shore-based viewing points on the North Coast.
Is the Trinidad Head trail hard?
The first fifth of a mile is steep — around a 14% grade — before easing to about 8% and then leveling. The opening half mile is paved; after that it's gravel and singletrack.
Are dogs allowed on Trinidad Head?
Yes, on a leash. BLM's guidance for the site is explicit about leashing.
