Not a muskrat. 

We will be developing a future website to more fully describe the park and its many intriguing attributes. 

There was a day long, long ago when an enterprising soul decided to raise muskrats in the area.  He eventually turned them loose into the wild; hence the name, "The Rat Farm."

Ahjumawi Lava Springs State Park

Ahjumawi Lava Springs State Park is located north of the town of McArthur, California and is accessible only by boat, (boat rentals are available locally).  From McArthur, take Main Street north off of State Highway 299 E, (just east of the Intermountain Fairgrounds).  After about 1/2 mile, bear right and cross over the McArthur Diversion Canal.  Follow the dirt road another three miles to the Rat Farm Boat Launch and parking area.  Question: Guess why they call it "The Rat Farm?" 

Please note:The main service bridge is out.  Please be prepared to pack in and pack out everything... nothing left behind.  06/06/2018

A typical campsite/picnic area. 

There is currently no reservation system, so it's first come - first served.  There are nine campsites, spread from 1-1/2 miles from the boat launch to 3 miles.  Each site has a food locker, a fire ring and a picnic table.  You must bring your own water or filter available water at the park.  Bring mosquito repellent and watch out for bears, (not necessarily of the ticket-writing variety). 

Ahjumawi Lava Springs State Park is one of three parks under the MBFIA umbrella.  The other two are McArthur ~ Burney Falls State Park and Castle Crags State Park.

The Pit River Tribe and its bands have lived in northeastern California since ancestral times and named the area Ahjumawi, meaning "Where the waters come together."  The waters which come together are Big Lake, Tule River, Ja She Creek, Lava Creek and the Fall River. 

Together, they form one of the largest freshwater spring systems  in the world.  Within the park, you'll find recent lava flows, lava tubes, craters, fishing, animal life, a wide variety of birds, primitive camping and environmental campsites.
