Humboldt Redwoods State Park

Featuring the Avenue of the Giants
California > Humboldt Redwoods and Vicinity

The Eel River

For the sheer size of its trees, no redwood park can beat Humboldt Redwoods. The world’s densest and most impressive stands of big trees are found here, along the Eel River and Bull Creek. Many of the most iconic images of the redwood forest come from Humboldt Redwoods — roads meandering through tall narrow canyons formed from huge trees, dark cathedral-like groves, plush carpets of redwood sorrel.

Surprisingly, these monster redwoods grow well inland, in an environment that’s much drier than the other Humboldt County redwood parks. A 3,000-foot-tall ridge to the west shields the park from ocean breezes, making for hot and dry summer days, but a tendril of ocean fog creeps south along the Eel River valley most summer nights to sustain the redwoods.

Most of Humboldt Redwoods' old-growth trails are short loops. The Avenue of the Giants in particular is mostly made up of small groves that are right next to the road, although the groves are still pretty spectacular. The only long old-growth hike is the Bull Creek Flats loop.

Despite the limited old-growth hiking, Humboldt Redwoods today is a absolute must-see for anyone interested in redwoods.

Other trails

Drive-in campgrounds


Baxter and Hamilton Barn Environmental Camps

May–Sep · $20/night + $8

These minimally-developed camps require a short walk to your site and don’t have showers or flush toilets, but provide a much more peaceful, natural experience. It’s like a backpacking camp but you don't need a backpack.


Albee Creek Campground

May–Oct · $35/night + $8

A small, quiet campground way out on Mattole Road just past the end of the old-growth redwoods. It’s mostly in the deep shade of small second-growth redwoods, but a few sites are at the edge of a sunny meadow.


Hidden Springs Campground

May–Sep · $35/night + $8

A large, sprawling campground that’s very spread out and has lots of privacy, but you have to drive to visit any redwood groves.


Burlington Campground

Open all year · $35/night + $8

Clean, well-maintained, and in a convenient location, but gets a lot of traffic noise and is in a heavily-logged grove with lots of huge stumps.

Whiskey Flat Trail Camp

Open all year · $5/person/night

In a small but very attractive old-growth redwood grove, this is the most scenic of Humboldt Redwoods’s trail camps.


Hanson Ridge Trail Camp

Open all year · $5/person/night

A quiet, remote trail camp well off the main trail to Grasshopper Peak.


Bull Creek Trail Camp

Open all year · $5/person/night

Open all year · $5/person/night

Conveniently located just below Grasshopper Peak, under a spruce tree at the edge of a meadow.

Johnson Trail Camp

Open all year · $5/person/night

The most popular trail camp in Humboldt Redwoods. Used to have some cabins, but they’re now collapsed.

Printed trail maps of Humboldt Redwoods

There’s no cell phone coverage in the main body and north end of the park, even in the towns; only the south end (Miranda and Phillipsville) has cell phone coverage. So to use any web-based maps in the park, you have to download the maps for offline use.

As far as I know, there are only three printed trail maps of the park:
