Forest Therapy @ Sugarloaf Ridge State Park
May 22 @ 9:30 am – 12:30 pm

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. Recent articles have been written up in Oprah, Time Magazine, and National Geographic, as well as numerous other publications. Sugarloaf Ridge State Park hosts a Forest Therapy Series as part of its ParkRx Program the 4th Saturday of each month. These walks are led by certified ANFT (Association of Nature and Forest Therapy) practitioners. Visit natureandforesttherapy.org for more info about this practice.

Tickets are $20 or free with a 2021 ParkRx from a Sonoma County Medical Provider (click here for more info).

Wednesdays Wondrous Nature Walks with a Naturalist @ Sugarloaf Ridge State Park
May 26 @ 12:30 pm – 3:30 pm

After an unusually warm and dry spring, the wildflowers are blooming earlier and it’s already butterfly and dragonfly season! We’ll be looking up as well as down to discover what’s flying around while learning a little about riparian, mixed evergreen, and meadow habitats along the way. As always, we will take our time to enjoy and identify the wildflowers, butterflies and dragonflies, and to catch our breath on the uphills.The 5/5 route takes us on the Creekside and Hillside trails returning via Meadow.

On 5/12 we’ll explore Pony Gate to Canyon and back on the upper section of Pony Gate for our only views and anything we might have missed.

On 5/26, we’ll climb up Lower Bald to the Vista with Meadow on the way back. This is a slightly longer (please budget 4 hours) and more strenuous hike but the flowers, butterflies and dragonflies will be be plentiful and worth the extra time and effort.

Meet outside the Visitor Center. Wear hiking shoes, layers appropriate for weather, bring water, your mask, a camera, and wildflower/butterfly/dragonfly guides if you have them. $10 plus parking fee. Adverse weather cancels and will be announced by 9AM the day of the hike.

Sugarloaf’s PPPP (Personal Porta Potty Program)

 Each campsite has its own porta-potty which our dedicated campground Staff cleans between each set of campers.  “The feedback from campers has been overwhelmingly positive”, said campground manager Woody Woodbury. “They like the safety as well as the convenience of having a toilet near their site,” he continued.

  • Honoring Earth, Honoring Volunteers
    Sonoma Ecology Center and our illustrious, dedicated volunteers help us honor Earth every day, and we’d like to thank them for helping us take care of little patches of our planet right here in Sonoma Valley. In partnership with One Tree Planted and Simply Solar, volunteers and our restoration crew helped clear out invasive broom plants on Sonoma Creek. Scotch and French brooms were introduced in the 1800s and grow well here, so much so that they choke out native plants. When they die they create fire fuel ladders that are highly flammable.  Over at Nathanson Creek another great crew led by Sonoma Ecology Center’s “Earthling” teen volunteer group cleaned up trash and learned about pollinators, plants and ways to protect our planet. Our trail restoration work at Sugarloaf Ridge State Park continues with volunteers repairing steps and bridges, clearing debris, installing signs and generally taking care of the park’s trails. Large portions of Sugarloaf burned in 2020’s Glass Fire, and other portions — some overlapping — burned in the 2017 Sonoma Complex Fires. With… Read more »
  • A message from NEST student, Alexandra Huerta
    As someone who has always admired the grandeur of the outdoors and has an ever-present curiosity for exploring, understanding and preserving our natural world, studying environmental science just made sense. As a Southern California native, my summer days as a youth were full of salty hair, sun kissed skin and bare feet whenever possible. My pursuit of higher education took me to Penn State, where I was surrounded by an entirely new population of research driven, hard-working classmates. My time at Penn State not only offered me a well-rounded education, but it also gave me the opportunity to experience beautiful changing seasons, meet people from completely new and different walks of life, and taught me the value and importance of a sense of community. After graduating from Penn State, I moved back to California, eventually finding my way up the coast to Sonoma Valley. Sonoma has so much to offer us, teeming with natural beauty that we are able to appreciate all thanks to efforts from local conservation groups, local agriculture that provides us with farm fresh food… Read more »

  • Getting to Know Dr. Dan
    For many years before settling with his family in Sonoma Valley, Dan Levitis was an “itinerant scientist” as he puts it, traveling the world, doing field work, taking academic posts, and gaining experience as a scientist and teacher. Born in Washington, D.C. and raised in Maryland, with a Ph.D. in integrative biology from UC Berkeley, […] Read more »
