Sugarloaf Ridge State Park is named for the shape of the ridge at its southern edge. In the 1800s, sugar was molded into cone-shaped loaves; many hills and mountains with a conical shape were whimsically called “sugarloaf.” The 4,020-acre park is located northeast of Kenwood in the Mayacamas Mountains between the lush Sonoma and Napa valleys and has 25 miles of trails for hiking and horseback riding. Elevations in the park range from 600 feet at the entrance to 2,729 feet at the top of Bald Mountain, overlooking the Napa Valley and Mount Saint Helena to the north. On clear days, you can see the Golden Gate Bridge and the Sierra Nevada from Bald Mountain’s summit. 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. Deer, gray foxes, the occasional bobcat and coyote can be seen in the park. In spring, wildflowers provide a colorful palette across the green hills. Temperatures during spring and fall are mild. The wettest months - from November to April - can bring 30 to 40 inches of rain. Wintertime lows can drop into the 20s, but daytime highs average 50s and 60s. Summer is hot and dry, often in the 90s, cooling to the 40s in the evenings. Wear a hat, and bring drinking water. Dogs are not allowed on trails or in the backcountry areas.
Jeff C. on Bald Mountain Trail
Great 360 views. San Francisco to the South, Snow Mountain North, Sierra's to the East.
Frankly difficult trail but amazing valley and hillside views. Weekend hiker take note -- some parts of the trail are tough and this earned its "hard" rating.
View at the very top a non existent, unless you're standing on a rock by the side of the plateau.
The views further down are phenomenal, and you can see all the way down the valley to SF.
There are sections with loose rocks in the trail so wear decent shoes.
It's an out and back trail, and the descent from the summit isn't easy!
