biological diversity, protecting its most
valued natural and cultural resources, and

When the Spaniards first tried to take their lands
and resources, ca. 1823, the Wappo successfully
resisted. Before long, however, the people were
forcibly moved from their traditional lands to
reservations, where they lived with other native
groups. Despite their

Natural History
The park encompasses three distinct ecological
systems: chaparral-covered ridges, oak/fir woodland
along the open meadows, and redwood forest
in the Sonoma Creek canyon. Big-leaf maples,
madrone, California laurels, gray pines and alders
also grow here. California lilacs, coyote bush, toyon,
and winebush make up some of the chaparral
community. As you hike, watch out for poison oak
and, along the creek, stinging nettles.
PARK HISTORY
Native People
Anthropologists believe that the Wappo people
are one of the oldest native California groups,
descended from the first people to settle here.
For thousands of years, they led fairly stable lives
on lands that produced everything they needed
to thrive. The Wappo gathered obsidian for arrow

Canyon Trail waterfall
Sonoma Creek begins in the park and runs for
three miles through its southern portion. The creek
is not deep enough for swimming and often dries
up by late summer. Following the winter rains, a
picturesque 25-foot waterfall flows along Sonoma
Creek below the campground. In the spring, the
park comes alive with wildflowers such as California
poppies, cream cups, penstemon, buttercups,
shooting stars, trillium, and Indian warrior. Less
common are golden fairy lantern,
zigadene and fritillaria. Clarkia, scarlet larkspur, Mariposa lilies, monkey
flowers and Indian pinks bloom in
early summer. Invasive yellow
starthistles and tarweed abound in
late summer.
Ranching
By the 1870s, a number of settlers
were living in the hills near Sugarloaf
Ridge. Farming was limited and
marginal. One settler cut and slowly
burned trees to make charcoal that
was sold in San Francisco. Eventually
“gentlemen farmers” came to own
Old ranch barn Sugarloaf Ridge; hired managers ran
their ranches while they tended to
other businesses in town.
The State of California bought the property
in 1920 to dam the creek and provide water for
Sonoma State Hospital, but neighbors along the
creek objected. Until World War II, the area was
used for camping, picnicking and a Boy Scout camp.
In 1942 the land was leased for grazing,
and it became part of the California State Park
System in 1964.
RECREATION
Camping
The campground, located around the meadow near
Sonoma Creek at an elevation of 1,200 feet, has
49 campsites that can accommodate trailers and
campers up to 24 feet. Each site has a table and a
fire ring, with flush toilets and drinking water nearby.
Group camping
The group campground accommodates up to 50
people. There is one large barbecue and fire ring,
with water faucets and chemical toilets.
Picnicking
Across the creek from the campground are picnic
sites with tables, barbecues and day-use parking.
Fishing
Trout fishing in Sonoma Creek is best in late spring
and early summer (the creek is not stocked). Fishing
season varies each year—please consult current
California Fish and Game regulations. Anglers over
the age of 16 must have a valid California fishing
license.
Hiking
The park has 21 miles of trails that wind through the
chaparral, oak and fir forest, and the redwoods in
the canyon along Sonoma Creek.
THE ROBERT FERGUSOn OBSERVATORY
The dark night sky here makes this a perfect location
for an observatory. Named after a Sonoma county
amateur astronomer, the observatory is located
near the group campground and surrounded by a
protective ring of hills, decreasing the light pollution
from nearby cities. This astronomy observatory
houses several telescopes. The observatory is open
to the public on select weekends throughout the
year for both night and solar viewing. Per-person
fees are charged at the door for night viewing.
accessible features
The visitor center and parking are generally
accessible. Assistance may be needed with
the portable restroom at the visitor center. For
information on disabled access to the observatory,
call (707) 833-6979 or visit www.rfo.org for details.
PLEASE REMEMBER
Schoolchildren enjoy the visitor center.
Classes teach visitors about the night sky, how
to make a telescope, and more. For information
or group reservations, call (707) 833-6979 or visit
www.rfo.org.
PLANET WALK
This scale model of the solar system, designed
to fit within Sugarloaf Ridge State Park, allows
you to “hike” through the entire solar system
by shrinking it more than 2,360,000,000 times.
Our sun is large enough to hold a million
Earths, yet it is only a middle-sized star. At
the scale used for this model, the nearest
neighboring sun is more than 10,000 miles away.
Each step you take is equal to nearly one
million miles of empty space.
To begin your walk, start at the sign
representing the sun in the southeast corner
of the observatory parking lot. If you take one
step every five seconds, you will be walking at
the speed of light, but plan on 1/2 to 2 hours for
your hike.
Enjoy your journey!
• Pets must be controlled at all times. They
must be on a leash no longer than six feet, and
kept inside a vehicle or tent at night. They are
permitted in the campground and picnic area,
but not on park trails or in the backcountry
areas. Please clean up after your pets.
• Fires are allowed only in the fire rings provided.
You may use your portable stove or barbecue,
but only in the established camping and picnic
areas. Wood gathering is not allowed—dead
wood is part of nature’s recycling system.
Purchase firewood at the entrance station.
• Smoking is limited to developed areas. The
park becomes tinder-dry in summer when fire
hazard is high; please do not smoke on trails.
• Quiet hours are 10 p.m. to 6 a.m. Generators may
only be operated between 10 a.m. and 8 p.m.
• Plants and wildlife are protected. Do not pick
the flowers. Their
