Our Mission
Annadel
State Park
The mission of California State Parks is
to provide for the health, inspiration and
education of the people of California by helping
to preserve the state’s extraordinary biological
diversity, protecting its most valued natural and
cultural resources, and creating opportunities
for high-quality outdoor recreation.
Start in a cool, shaded
forest—move through
mixed oak to expansive
open meadows and around
a refreshing 26-acre lake
through tangled chaparral—
California State Parks supports equal access.
Prior to arrival, visitors with disabilities who
need assistance should contact the park at
(707) 539-3911. If you need this publication in an
alternate format, contact interp@parks.ca.gov.

A
nnadel State Park sits in the historic
Valley of the Moon, an area popularized
by author Jack London. This largely
undeveloped park is 60 miles north of San
Francisco on the eastern edge of Santa
Rosa. The park has more than 5,500 acres
of rolling hills, seasonal streams, meadows,
and woodlands free from modern intrusions.
Summers are hot and dry, with
temperatures reaching into the 90s and
evening lows near 50 degrees. At times
during the summer, coastal fog penetrates
inland, providing cool evenings. Most
of the area’s 30 inches of rain occur from
November to April. Wintertime low
temperatures can drop to the mid-20s with
daytime highs in the 50s or 60s.
PARK HISTORY
For thousands of years, the Southern
Pomo lived near what is now the park. No
permanent village sites have been found in
the park, but these lands were important as
trading grounds and as a source of obsidian,
a volcanic rock that was traded with other
tribes, who would work it into scrapers,
knives, arrow points, and spearheads.
In the early 1800s, Russian and Aleutian
fur trappers arrived in the area to establish
Fort Ross, now a state historic park. They
found the Pomo willing traders and hard
workers. The Fort Ross settlers may have
been among the Pomo’s first contact with
non-native people.
Gold rush miners and settlers who wanted
the Pomo lands arrived after 1848, bringing
disease and violence. Surviving Pomo went
to nearby Mission San Francisco Solano,
were forced into involuntary servitude, or
were moved onto reservations.
Though the Pomo resisted these
drastic changes to their way of life, many
succumbed to overwork and to European
diseases to which they had no resistance.
With the arrival of Europeans, cattle
ranching and farming gradually replaced
the native pattern of hunting and
gathering. By 1837 this area had become
part of Los Guilicos Rancho, a Mexican
land grant covering about 19,000 acres.
Eleven years later, the property was
acquired by William Hood, who came here
from his native Scotland.
In the late 1800s, sheep and cattle grazing
gave way to the quarrying of cobblestones.
This was the major source of income for the
Wymore and Hutchinson families, the area’s
principal landowners, until the early 1900s.
Cobblestones were used in the building of
San Francisco and other west coast cities, as
well as in their reconstruction after the 1906
earthquake. However, cobblestone roads
were not suitable for motor vehicles,
and by the 1920s, demand for them had
significantly declined.
In the 1930s, entrepreneur Joe Coney
bought 3,200 acres of oak woodlands
near Santa Rosa from Irish immigrant
Samuel Hutchinson. Hutchinson had
named his ranch by combining the name
of his daughter, Annie, with dell (a small,
secluded, wooded valley). Under the
Coneys’ ownership, it became known
as “the Annadel Farm.” Coney built a
hunting and fishing retreat for his friends.
He stocked the property with game
birds and filled his man-made lake, Lake
Ilsanjo (built in the mid-1950s and named
for the Coney couple, Ilse and Joe), with
black bass and other fish. When his
fortunes began to diminish in the 1960s,
Joe Coney decided to sell the ranch.
California State Parks acquired Annadel in
1971, and it became a state park in 1974.
Ledson Marsh
NATURAL HISTORY
Annadel’s terrain consists of a diverse
range of plant communities, including
meadows, grasslands, forests, and
chaparral areas. Environmental conditions
favor the development of these varied
habitats, making it possible to view a wide
variety of birds and animals during a visit.
Deer are commonly seen around sunset,
and coyotes are among the many species
of wildlife here.
RECREATION
Hikers, equestrians, mountain bicyclists,
runners, and nature-lovers can choose
among more than 40 miles of trails.
Elevation gains and degree of difficulty
vary with each trail.
Warren Richardson Trail
TRAILS
Warren Richardson Trail (fire road) —
This trail, commemorating a prominent
cattle rancher and hop grower, begins at the
parking lot at the end of Channel Drive and
goes uphill through a forest of Douglas-fir,
bay, and redwood trees. Parts of the trail are
home to pileated woodpeckers and pygmy
owls. In the spring, keep an eye out for
calypso (fairy slipper) orchids between the
Two Quarry and Steve’s “S” Trail junction. At
the 900-foot elevation, the forest gives way
to open meadows and mixed oak woodlands,
and you will get your first glimpse of Lake
Ilsanjo when you intersect the North Burma
Trail. The walk generally takes an hour to
cover the 2½ miles to the lake.
Picnic tables are scattered along the
shoreline. Circle the lake and return via
Steve’s “S” Trail to make a 6-mile loop.
Cobblestone Trail — This narrow, 2-mile
trail beginning at the auxiliary parking
area on Channel Drive is rocky on the
bottom third, then flattens as it nears the
boundary of the park. Farther along this
route is the Wymore Quarry. At one time,
a gravity-powered, narrow-gauge tramway
transported the cobblestones produced at
the quarry to a small-gauge railroad line,
which is now Channel Drive. The stones
were then transported to San Francisco
and Sacramento, where some of the oldest
streets are still paved in cobblestones. The
trail ends at Rough-Go Trail.
Spring Creek Trail — There are two access
points to this trail; one is the service road
from Spring Lake’s horse-trailer parking
area, and the other is from Santa Rosa’s Viet
Nam Veterans’ Trail. This trail is completely
shaded by alders, redwoods, and arching
bay trees that grow along the creek canyon,
making this one of the most pleasant trails
in the park on a hot summer day. The trail
begins with an increase in elevation and ends
at the lake.
Canyon Trail (fire road) — This 2-mile trail
begins at the intersection of Spring Creek
Trail near a wooden bridge. The trail’s
elevation increases steadily. At the top,
discover a panoramic view of Santa Rosa,
the Mayacamas Mountain Range with the
Geysers, and Mount Saint Helena. Colorful
“Indian warriors” bloom from March
through May at the Marsh Trail intersection.
Canyon Trail ends at the lake after passing by
Hunter Spring, where a horse-watering trough
is located.
Marsh Trail — This trail climbs steadily from
its beginning at the intersection with Canyon
Trail. Marsh Trail skirts the northern flank of
Bennett Mountain. Higher elevations provide
views of Lake Ilsanjo and the Mayacamas
Mountain Range. The trail runs through prime
oak woodlands, grasslands, and cool islands
of coastal redwoods. Threatened California
red-legged frogs, popularized by Mark Twain’s
The Celebrated Jumping Frog of Calaveras
County, live at Ledson Marsh, where the trail
terminates. (Please step with
care.) The structures attached
to various trees surrounding
the marsh are nesting boxes
for wood ducks.

Lawndale Trail — The
trail begins at the
eastern end of the
park off Lawndale
Road from Highway
12 near Kenwood.
Steve’s “S” Trail —
Restricted to hikers
only, the route begins
and ends at the
Warren Richardson
Trail. This steep path
is shaded by firs
and bay trees. The
trail is named for
Steve Hutchinson,

Drive for a very short distance before
returning to the dirt trail. This area was
one of many quarry sites in Annadel.
OTHER FEATURES
Lake Ilsanjo — This man-made, 26-acre
lake is not stocked, but bluegill and
largemouth bass live here. All anglers 16
years of age or older must carry a valid
California fishing license. Visit the site at
www.wildlife.ca.gov for fishing regulations.
Ledson Marsh — First built as a reservoir
to water eucalyptus trees, the marsh
is now mostly overgrown with cattails,
tules, and native grasses. During the
winter months, water collects here and
overflows into Schultz Canyon. The bridge
at this spillway helps to protect the rare
California red-legged frog.
ACCESSIBLE FEATURES
Two accessible picnic tables sit on a
firm surface under a tree off the main
parking lot at the end of Channel Drive.
An accessible portable
restroom is nearby,
and the parking lot has
designated accessible
parking. The packed dirt
lot and the paths to the
restroom and tables
are generally accessible.
Accessibility is
continually improving.
