The Largest Forest in California: The Shasta-Trinity National Forest

At over 2 million acres in size, the Shasta-Trinity National Forest is the largest forest in the entire state of California. It is located north of Redding and encompasses a huge swathe of Northern California, including the high-altitude Mount Shasta. In fact, there are more than 6,000 miles of running water in this forested region in the form of rivers. And this doesn’t even begin to address the large number of lakes and other mountains found in this region!

The Shasta-Trinity National Forest was once smaller and made up of two primary national forests. These forests were once named the Trinity National Forest and the Shasta National Forest. They have since been combined. This popular region in California hosts five different wilderness areas, including mountain peaks, rocky crags, and much more!

From Castle Crags to Shasta Lake, the Shasta-Trinity National Forest brings together many types of biomes and natural areas. Given the fact that it spans a wide swathe of California in between the Pacific coastline and mountains to the east, it’s a huge and fascinating regional area with plenty to offer the average recreational enthusiast. It’s certainly difficult to fathom 2 million acres, but California is large enough to boast a forest this large!

Where Is the Shasta-Trinity National Forest Located on a Map?

The Shasta-Trinity National Forest is between the upper Sacramento Valley and the Shasta Valley. Its lands are in parts of Trinity, Shasta, Siskiyou, Tehama, Modoc, and Humboldt counties. A nearby city is Redding.

History of the Shasta-Trinity National Forest

Given the fact that the Shasta-Trinity National Forest was once comprised of two separate forested areas, what is its history like? As early as 1905, President Theodore Roosevelt designated over one million acres in Northern California as the Trinity Forest Reserve. Later that same year, the Shasta Forest Reserve was also created. The two reserves were combined into the Shasta-Trinity National Forest in 1954. But this region of California was occupied long before our modern era.

Thousands of years ago, Native American tribes and groups occupied this region. The National Forest Service works in tandem with a dozen or more state and nationally recognized tribes to maintain the forest, which includes indigenous archeological areas as well as sacred monuments. There are many regions throughout the Shasta-Trinity National Forest that have evidence of inhabitants as long ago as 5,000 years!

Gold Rush Era

This forest also has plenty of history surrounding the gold rush times of the early 1800s. Given the fact that Mount Shasta reaches over 14,000 feet into the sky, it was a great landmark for travelers and pioneers crossing the nation in search of gold and a new life. Many people made it to California using landmarks found within this wilderness area. The Shasta-Trinity National Forest provided newcomers with plenty of timber, resources, and, of course, gold!

But copper was also an extremely popular ore mined in this region. In fact, multiple towns and settlements were created to mine copper in the 1800s. Nowadays, the majority of these towns no longer exist and are in fact sunk beneath the man-made waters of Shasta Lake! This dammed region was created in the 1940s. It also covers some remnants of the Oregon Trail as well as the Central Pacific Railroad.

What to Do in the Shasta-Trinity National Forest

If you are interested in visiting the Shasta-Trinity National Forest, there are a number of things you can do during your time there.

Besides hiking, you can bring along a boat or kayak to enjoy Shasta Lake. There are many different regions of the lake to explore, with some locations offering evidence and sightseeing of some of the aforementioned copper mining towns. You can camp throughout the forest as well, with fantastic campgrounds located at Castle Crags, near Lake McCloud, and plenty of sites surrounding Medicine Lake.

Speaking of Medicine Lake, this region is technically home to the largest volcano in California.
