Calendar of Events

Join Sonoma Ecology Center and Team Sugarloaf and embark on an unforgettable journey through the heart of Sonoma County’s most pristine and breathtaking landscapes with our exclusive fundraising hike. This event will be a grand tour of the Mayacamas Mountains in the northern half of Sonoma Valley, where we will pass close to the headwaters of Santa Rosa and Sonoma Creeks. This unique adventure offers participants a rare opportunity to traverse through areas usually closed to the public, such as the recent Perry Addition to Sonoma County parks. Whether you choose the 11-mile classic route or the 17-mile epic option, you’ll be treated to a day filled with stunning vistas, challenging trails, and the camaraderie of fellow nature enthusiasts. As you navigate through rolling hills, serene creeks, and towering oaks, you’ll push your limits and contribute to a noble cause. The hike culminates in a communal barbecue dinner, where stories of the day’s journey can be shared among new friends.

Sign up today to secure your spot in this remarkable experience and help us support the preservation of Sonoma County’s natural treasures. Sponsorship opportunities are available for those looking to make an even greater impact.

This year, we have two versions:

1. Classic Route  – from the Los Alamos parking lot in Hood Mountain Regional Park to Sugarloaf’s day-use picnic area via the McCormick Addition and Bald Mountain Trail. 11 miles; 3,200 ft of elevation (bus from Sugarloaf).

WHY SUPPORT US?

Sugarloaf Ridge State Park is operated by Sonoma Ecology Center, a 501(c)(3) nonprofit organization. While Sugarloaf is a California State Park, we do not receive operational funding from the State. It is our visitors, donors, volunteers, and members who make it possible for us to keep Sugarloaf Ridge State Park open for the community to enjoy.

Since 2012, Sonoma Ecology Center has worked to make the park accessible and welcoming to a broader audience through community-focused programs.

Some of our programming highlights include:

• Our Senderos Program targets the Spanish-speaking community, bringing thousands of new visitors to the park for nature events and first-time camping experiences. Learn More.
• The Slow Journeys Program offers nature hikes and events on flat, smooth paths, ensuring accessibility for all visitors. Learn More.
• The ParkRx Program at Sugarloaf is the nation’s most active, providing over 1,000 participants annually free access to approximately 90 activities, including fitness hiking series, yoga hikes, Tai Chi classes, and forest therapy sessions, all prescribed by medical providers. Learn more.
• We have earned recognition as a role model in establishing impactful relationships with the local Native American tribe, the Mishewal-Wappo. Our relationship is grounded in respect, patience, and courage. Learn More.

What are the keys to our success in building vibrant and inclusive programing?

• Deep community ties: We continuously strengthen our connections across all community sectors, enhancing our understanding of community needs and fostering collaborations with other local organizations.
• Innovative marketing and outreach: Our multi-channel marketing strategy reaches every community member, featuring a large email list, a dynamic social media presence, collaborations with local newspapers and websites, online advertising, and partnerships with numerous local organizations and groups.
• A Committed Volunteer Program: Many of our programs, including ParkRx and Slow Journeys, rely on a dedicated and skilled volunteer force, allowing us to offer these events at a significantly lower cost than other organizations.
• Test-and-learn philosophy: We continuously evolve our programs through learning, modifying, and documenting, ensuring they become impactful and financially sustainable.

ROUTE DETAILS

Classic Route:  Participants will arrive at Sugarloaf Ridge State Park by 8:45am, with shuttle buses departing at 9:00am for Hood Mountain Regional Park. The hike begins at the Los Alamos parking lot, taking the Santa Rosa Creek Trail to Homestead Meadow and entering Sugarloaf via the McCormick Addition. The route ascends Quercus Trail, passes the former site of the Grandmother Oak, and stops briefly at Red Hill before continuing up Maple Glen Trail. After lunch atop “Hill 2530,” hikers return to Sugarloaf via ascending Bald Mountain, concluding with a barbecue dinner in the day-use area around 3:30pm. The journey spans roughly 11 miles and climbs 3,200 ft in elevation.

Epic Option (for advanced hikers only): Meet at Sugarloaf’s Visitor Center at 6:15am for a 6:30am departure via Pony Gate and Goodspeed Trails. Meet up with the group hiking from the Los Alamos parking lot at the Santa Rosa Creek crossing (in Hood Mtn Regional Park) at about 10:00am, before entering Sugarloaf’s McCormick Addition.

Pack a lunch for the stop at Hill 2530, at least half a gallon of water and electrolytes, sun protection, and additional socks. Be prepared to walk 11 or 17 miles (depending on the route you registered for) over steep and sometimes rough terrain, with a stream crossing of minimal depth. Dress appropriately for the weather and the ticks.

Ticket sales end on 4/16 to give us an estimate of how many buses we will need for shuttling and how much food to prepare.

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

Have you heard about “Shinrin-yoku” or “forest bathing”? Here is an opportunity to take a walk and experience the practice for yourself. Learn techniques to maximize the health benefits and stress reducing qualities of this walking practice. Shinrin-yoku originated in Japan and is gaining popularity in the United States for its documented health benefits.

This practice takes a walk in the woods to another level. A centering and calming restorative practice, it promotes balance and restored vitality through a quality of presence and heightened sensory awareness. Sugarloaf Ridge State Park hosts a Forest Therapy Series as part of its Park Rx Program the 4th Sunday of the month led by certified Association of Nature and Forest Therapy (ANFT) practitioners.

We invite you to join us on this therapeutic experience of sights, sounds, scents, touch, and memory. The outing begins at the White Barn and meanders less than one mile from the start point in a reverie of introspection and connection to the natural world.

Tickets are $20 or free with an April 2024 or newer Park Rx from a Sonoma County Medical Provider. Click here for ParkRx information. To sign up with a ParkRx, please email a PDF of your Rx to alma@sonomaecologycenter.org.

Wear layers, comfortable footwear, bring water, sun protection, and if desired, a snack or a picnic to enjoy after the event. Parking fees apply. Heavy rains cancel.

Soundscapes are auditory landscapes that encapsulate the diverse and harmonious interplay of ambient sounds, from the wildlife to the non-biological, creating a rich and immersive sonic environment. Venture out on this auditory experience with Jack Hines, Soundscape Ecologist at Ear to the Wild and Sonoma Ecology Center’s GIS Specialist. As part of this year’s City Nature Challenge, we will learn about recording sound for submission to platforms such as iNaturalist or Merlin for species identification, or options to improve sound quality of recordings using external microphones. No mobility is required, as we will simply remain around the White Barn parking lot and adjacent areas, including the creek on the Creekside Nature Trail.

Meet at the White Barn. Bring water, layers, a full battery on your mobile device (or alternatively, an audio recording machine), a flashlight to light the way, and if you desire, a cushion to sit on.
