Animals in Sugarloaf
Saturday, August 13, 6:30-8pm

You’re invited to our Animal adventure! We’ll take a walk on Meadow and Hillside trails in search of signs and tracks made by animals commonly found in the park including bears, snakes, and bats. We’ll meet at the White Barn lot. Be prepared to walk approximately 1 mile. Bring plenty of water, insect repellent or long sleeves, a sweater, sun protection, and if desired, a snack.

Tickets require a $10 deposit per family to be refunded after the hike. To register, call Alma at 707 833 5712 Friday-Sunday from 9am-5pm. Parking fees, usually $10, will be waived for this event. We have vouchers for Sonoma Valley residents in need of transportation.

This event is planned around a primarily Latino audience. Families from underrepresented groups are particularly welcome. 

Ease of access: The entire walk is not recommended for strollers or wheelchairs. Meadow and Hillside trails are fire roads with two 100-foot hills and a small stream crossing. Meadow is passable by strollers or wheelchair up to the bridge, about a mile in, but is not officially an ADA trail.

Senderos Naturales is supported by Route to Parks, a grant of Parks California.

Parks California’s unique multi-stakeholder partnership approach strengthens communities while fostering love and stewardship of public lands. The Route to Parks grant of $15,000 will help more people have access to the resources they need to lead a healthy life outside Senderos Naturales. Parks California was founded as a key nonprofit partner of the California Department of Parks and Recreation to help strengthen and inspire all to experience these extraordinary places.

Limited-Mobility Dusk Birding @ Sugarloaf Ridge State Park
Aug 14 @ 6:00 pm – 7:30 pm

Many people know birds are most active at dawn, but dusk is second daily peak of bird activity, and you don’t have to be an early-bird to experience it. Join Dr. Dan Levitis at Sugarloaf Ridge State Park for a slow, wheelchair-accessible excursion designed for those new to bird-watching. Bring binoculars if you have them, but we’ll have a few pairs to lend, and will be doing as much listening as looking. By the time we finish it will be dark, so in addition to water, consider bringing a flashlight and a jacket. Tickets are $10. Meet at the White Barn lot. Parking fees apply.

Ease of access: the entire event will take place on the Creekside Nature Trail, our 0.9mi ADA-accessible trail. Some benches available along the way for resting for those who need them.

Sonoma Garden Park Volunteer Workday @ Sonoma Garden Park
Aug 19 @ 9:00 am – 12:00 pm

At noon you will be happy to enjoy a light garden fresh lunch at our shady picnic area provided by Sonoma Ecology Center as a thank you to our wonderful volunteers!

Sugarloaf Perspectives @ Sugarloaf Ridge State Park
Aug 19 @ 7:00 pm – 8:00 pm

Storytelling is humanity’s oldest artform, likely originating before the cave paintings of the Stone Age. This summer we introduce “Sugarloaf Perspectives”, a storytelling series that brings new voices and people to the park while teaching about the natural environment. Every other Saturday, instead of our regular family campfire, we will have a Perspective.

On 6/25, world-renowned multi-disciplinary artist Bernie Krause will present how sound became his life-long pursuit, and how it applies to conservation.
On 7/23, Megan Walla-Murphy re-introduces bear culture to Sonoma County.
CANCELLED: On 8/6, we’ll learn about the secret lives of Alma and Arsel, leaders of the Senderos Naturales program.
On 8/20, we welcome Desi Harp, member of the Onasáti tribe (mistakenly called “guapo” by the Spanish and “wappo” by Anglo-American settlers) to regale us with song, dance, and the story of creation.
On 9/3 we are left gasping from laughter induced by SEC’s Educator Johny Ehlers, and finally, on 9/10, Sonoma Ecology Center’s ED Richard Dale and Park Manager John Roney relate how a partnership between non-profits, community, and government led to today’s operation of Sugarloaf Ridge State Park.

Tickets are $20. Meet at the amphitheater. We invite you to show up earlier than 7pm for a self-guided nature walk or picnic prior to the event. Parking fees apply.

Introduction to Nature Journaling @ Sugarloaf Ridge State Park
Aug 21 @ 2:00 pm – 5:00 pm
Nature journaling helps you enjoy the natural world in a whole new way. You can take just a short hike, or even stay in one place, and see, hear, smell and touch more than you ever thought possible. Using words, numbers and drawings, you will learn to record your experiences in a way that works for YOU. There are no rules, but you’ll learn some tips to get you started. NO art “ability” necessary!
After an introduction to materials and methods, we will explore around the group camp and start recording and sharing our observations. Back at the group camp, you will get a chance to try out some watercolor, colored pencils, watercolor pencils and drawing pencils.
This event is welcome to all, and accessible for those with limited mobility. Meet at the group camp parking area. You are welcome to bring any art supplies that you have, but just a pencil and notebook will do.
Tickets are $15 general, half price for students, youth (12-17 years old), Sugarloaf members, Sugarloaf volunteers, and free for under 12. Bring water, sun protection, a snack, and if desired, bring a picnic to enjoy afterwards. A $10 parking fee is applicable.

We have tools and trained crew leaders with tasks for all. Minors must be accompanied by a responsible adult. We will provide tools, and if allowed, lunch.

The practice of Forest Therapy has been shown to improve health and well-being.

These walks are led by certified Association of Nature and Forest Therapy (ANFT) practitioners. Visit for more info about this practice.
