Van Hoosear Wildflower Preserve Walk @ Van Hoosear Wildflower Preserve
Apr 19 @ 5:30 pm – 7:30 pm
Van Hoosear Wildflower Preserve Walk @ Van Hoosear Wildflower Preserve

Join Sonoma Ecology Center naturalists at Van Hoosear Wildflower Preserve for one of the most spectacular wildflower displays in all of Sonoma County. Experience a pristine spring grassland with numerous species in full bloom. The 162-acre property in the foothills of Sonoma Mountain is protected by a conservation easement made possible by Sonoma County Agricultural Preservation and Open Space District (Ag + Open Space) and the California Wildlife Conservation Board. The property is managed under a partnership with the landowner and Sonoma Ecology Center to protect the Preserve’s unique plants, thriving streams, and wildlife habitat. 

This outing is a beginning-level walk over a gently sloped land. Most of the walk is through grassland, generally not on trails, so the footing can be uneven. The walk crosses a few small creek channels, which sometimes have shallow water with stepping stones.

The dates for the Van Hoosear Wildflower Preserve Walks 2024 are:

EACH WALK’S REGISTRATION WILL OPEN 10 DAYS PRIOR TO THE EVENT TIME. THERE IS A LIMIT OF 2 TICKETS PER ORDER. You will be able to find when your desired walk will open registration by clicking “Get Tickets” at the bottom of this page.

Please note that these popular walks fill to capacity on a first-come, first-served basis every year, so early registration is encouraged! Walks will go on in light rain, but heavy rains will cancel the walk. 

Registration is required. Directions and day-of-contact information will be emailed upon registration. For additional information or questions about the outing, please contact Tony Passantino at 707.996.0712 ext. 124, or tony@sonomaecologycenter.org.

There is no charge for this outing, which is made possible by the voters of Sonoma County who fund the work of Ag + Open Space with a quarter-cent sales tax.

Headwaters to Headwaters Hike: A Mayacamas Hiking Adventure @ Sugarloaf Ridge State Park
Apr 20 @ 6:30 am – 5:00 pm

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).
  2. Epic Option – Sugarloaf’s main parking lot to Goodspeed Trail into Hood Mtn, down to the McCormick Addition and joining the rest of the group. 17 miles; 5,600 ascent. This is a rigorous hike for advanced hikers only (limited to 15 tickets).

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.

By supporting us, you contribute to a legacy of inclusivity, innovation, and community engagement at Sonoma Ecology Center’s management of Sugarloaf Ridge State Park.

Tickets: $95 each. Tickets include parking, shuttle transportation to Hood Mtn, snacks, drinks, and a BBQ dinner.
Underwriting Options: Help us defray the event’s costs and make it a true fundraiser. All of these options are tax deductible and include one ticket to the classic route of this hike.

  • Epic Underwriter: $5,000
  • Monumental Mover (and Shaker): $2,500
  • Peak Provider: $750
  • Sugar Sponsor: $500

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.
