Welcome to Sugarloaf Ridge State Park

Sugarloaf Ridge State Park contains the headwaters of Sonoma Creek. It runs through gorge and canyon, across the meadow floor, beneath scenic rock outcroppings, and is surrounded at times by redwoods and ferns. With 47 family sized campsites and 25 miles of hiking trails, it is the perfect place to spend time outdoors with your family!

Camping:  We have 44 campsites open, both reservable and first-come, first-serve in our lovely creekside campground.  And our Glamping sites opened April 1st–reservations available and booking fast!  For first-come-first-served sites call at 10:00 am.  Call ahead, these sites fill fast.

Field Zoology Course
Feb 19 @ 10:00 am – Apr 16 @ 2:00 pm


Location: Multiple Locations around Sonoma County (including Sugarloaf Ridge State Park)

Sonoma County is full of amazing wildlife discoveries for those that know how to make them. From the Mountain Lions of Sugarloaf Ridge State Park, the shorebirds of Bodega Bay, tiny plankton, dragonflies, to big old bears, thousands of species of wild animals call Sonoma County home.

In this course, students will learn how to find, document, and observe a wide variety of our native animals through a series of field trips to natural areas. Emphasis will be on learning field methods that students can employ with only low-cost equipment, and on recognizing the major groups of animals and how to photograph them. We’ll learn some ecology, evolutionary biology, and conservation biology along the way, but our focus will be on the field methods. Scholarships are available to reduce costs for those in need of financial assistance, and carpools can be arranged for those needing transportation.

Instructor: Dr. Dan Levitis studied zoology at the University of California, Berkeley, and has taught zoology, ecology, evolutionary biology, demography, and conservation biology at the university level. For Sonoma Ecology Center he has previously taught New Ecological Scientist Training, California Naturalist Training, and Climate Stewardship, as well as leading programs to document the biodiversity of Sugarloaf Ridge State Park and the Sonoma Developmental Center. He is Community Science Coordinator for Sonoma Ecology Center.

We have reached our capacity for scholarships. Please contact Tony at tony@sonomaecologycenter.org for questions.

What would life be like thousands of years ago in Wilikos (today known as Sugarloaf Ridge SP)? How are the stories of the Wappo people in Wilikos continuing to evolve today?
