Founders Grove Nature Trail in Humboldt Redwoods State Park

The driving force in the creation of the redwoods state and national parks on California’s North Coast was the Save-the-Redwoods League. Founders Grove was selected to memorialize the originators of that league. Expect something special on this easy half mile hike. A guide accompanying this trail is packed with useful information, allowing hikers to thoroughly experience a redwood forest on Founders Grove Nature Trail.

The first attraction on the loop is Founders Tree, a 346 foot tall redwood that is 40 foot around. Like the rest of the grove, the Founders Tree honors the creators of the Save-the-Redwoods League, which was formed in 1917. The group purchased its first grove in 1921 in what is now Humboldt Redwoods State Park. Over the last 90 years, the league has protected 170,000 acres of redwood forests and contributed over 57 million dollars to their preservation.

At the start of Founders Grove Loop turn left and pick up a free trail guide. Numbered markers along the trail coincide with entries in a guide booklet, which add quite a bit of learning to the short hike. Hike the loop in a clockwise direction to follow the guide in order, and learn interesting factoids like:

A very large redwood can release up to 500 gallons of water into the air per day.


The greatest accumulation of plant mass ever recorded on earth was a redwood stand in Humboldt Redwoods State Park. This temperate rainforest has seven times the biomass (living and dead organic material) of that found in a tropical rainforest.

At the far side of the loop, reach the Dyerville Giant, a fallen redwood believed to be 1,600 years old. When it fell in 1991, the 370-foot tall redwood was the oldest, largest, and tallest tree in the grove (slightly taller than Niagara Falls!).

No visitors were present when the tree fell, but a sound like a train wreck was heard a mile away when the giant redwood fell. The demise of this 1,000,000 pound tree with a 17-foot diameter splattered mud fifteen feet up the trunk of another redwood, 50 feet away.

Founders Grove Loop offers an easy hike with approximately 25 feet of elevation gain. The sight of these great trees is astounding, but the added knowledge from the trail guide makes the forest even more impressive.

5 Comments on Founders Grove Nature Trail in Humboldt Redwoods State Park

  1. Although Humboldt redwoods is a bit farther drive, it’s beginning to grow on me the past few months, and is becoming a more common photography and hiking destination now.

    Sure enjoyed the recent autumn visit. It was a little bit wet, but not raining most of my visit, and the moisture gave very nice colors.

    Cheers … MDV

  2. I’m not finding in your site (or in any other) how to get back on Hi 101 upon exiting Founders Grove. As I recall, you can’t do it by going back toward where you got off (while southbound). I think you come out to the stop sign on Avenue of the Giants and turn left (south). But then I can’t recall if, after it goes over the freeway to the west side of it), there’s an on ramp to Hi 101 right there or of you have to drive all the way to Meyer’s Flat to get back on. Can you help?

    I love this forest more than anything imaginable. My heart aches for just another walk through. The smells, the trees, the plants, the sound of the river, the near perfect outdoor temperature, the way the wind blows through the redwoods causing the tops to slowly creek as they sway, the river otters swimming down the river. I miss it. The redwood forest is the closest thing you can get to heaven without actually being in heaven.
    My husband died and now I will never get to go there again. What a very sad thought. I could never make it up there without him. I want to cry.
