Join Certified California Naturalist Mary Good on a hike exploring the medicinal and edible plants of the park. Weaving in natural history, ethnobotany, herbalism and folktales, this walk will open your senses, as well as your curiosity to the abundance of plantlore in Sonoma County.

Tickets are $15-$20 sliding scale for general audiences, $7.5 for students, youth (12-17 year olds), Sugarloaf members, Sugarloaf volunteers, and free for children under 12. Meet at the White Barn parking lot. Wear appropriate clothing and footwear for two miles of leisurely walking and chatting over moderate and possibly muddy terrain. Bring at least a quart of water, and if desired, a snack and a plant identifying guide. Heavy rains cancel; parking fees apply.

Edible plant information is for educational purposes only. Foraging is illegal in CA State Parks. 

Ease of access: The White Barn parking lot has one van-designated parking spot and an accessible porta-potty. Creekside Trail has two trailheads. The trailhead from the White Barn is ADA compliant for about 0.1 miles. Our route for this hike veers off to the left across a narrow bridge and single-track trail that connects with Hillside. Hillside Trail is a gravel and dirt road with two 100-ft hills and a small stream crossing. Meadow is a mostly flat composite trail manageable by strollers and wheelchairs from the trailhead to about a mile in, although officially not an ADA-compliant trail. The entire loop is a fire road sometimes driven by authorized vehicles.

Community scientists John Hibbard and Alex Weishaar lead this easy-to-moderate 2-mile butterfly walk as part of 2024’s City Nature Challenge. We will encourage butterfly and bug photography; cameras, binoculars, hand lenses, and field guides are recommended. Stop by the greenhouse (across from the White Barn) between 11:00 am-12:00 pm prior to the walk for everything butterfly-related.

Meet at the White Barn for the walk. Tickets are $5 for adults and free for children under 18. Wear comfortable shoes, sun protection, bring at least a quart of water, a fully-charged battery on your mobile device, butterfly identification guides (if you have them), and if desired, a snack. Parking fees apply; rains cancel.

The 2024 City Nature Challenge runs from April 26 to 29. It’s a bioblitz-style friendly competition where cities are in a contest against each other to see who can make the most observations of nature, who can find the most species, and who can engage the most people. Learn more about City Nature Challenge or view the Sugarloaf Project here!

Participants of any level of experience can help find, photograph, record, and/or identify life in the park. Smartphones with the iNaturalist app will be our main tool, but those lacking phones are also welcome to participate. If you haven’t used iNaturalist, or haven’t made an observation for a while, this is your chance – just make sure to load the iNaturalist app on your phone before you arrive. This event is part of the Challenge along with other events scheduled from April 26-29.

Ease of access: The White Barn parking lot has one van-accessible parking spot and an accessible porta-potty. We’re unable to determine ease of access for the hike as the route will be decided the day-of by the hike leader and other logistics (temperatures, seasonality of butterflies, etc).

The Robert Ferguson Observatory (RFO) is open to the public at least once a month, usually on a Saturday near the time of the New Moon.

Star Parties: Presentations on astronomical topics are given in the classroom throughout the course of the evening. Starting at dusk, the Observatory’s three main telescopes are open for your viewing. Docents set up additional telescopes in front of the building. Friendly and knowledgeable docents are available to answer your questions.

You must have a ticket to attend, as we are limited to 40 attendees per County Health Orders. Proof of vaccination or a negative rapid test taken within the last 48 hours are also required to attend. Tickets are available at rfo.simpletix.com

FAQs:

1. Map and Directions
2. When to arrive: We keep the observatory open as long as there are visitors, but you must arrive within 3 hours after start time to ensure that we remain open for you. Summer Star Parties begin with tours and presentations until it’s dark enough for observing.
3. Bring warm clothing, even in summer—observing is done outdoors.
4. There is a short walk from the parking area to the Observatory and you may wish to bring a small flashlight.
5. White Light: No white lights should be used after dark; the observatory is a red-light-only area to protect everyone’s night vision. We will supply red cellophane to cover flashlights. Please note:
   ◦ Bring a SMALL flashlight (large camp lanterns, light sticks, etc., cannot be adequately covered by red cellophane).
   ◦ Cell phones or cell-phone flashlights are acceptable but must be covered in red cellophane. (No cell service at the observatory).
   ◦ Some head lamps are difficult to cover with red cellophane. Once covered, head lamps should be worn around the neck or used pointing down as they are usually very bright at eye level.
   ◦ Red flashlights are available for $5 at the observatory.
6. Alcohol is prohibited on Observatory grounds.
7. The Observatory is not open to the public except for scheduled events.

Classroom presentations are always offered on Star Party nights even if the weather is poor. For current conditions call the observatory at (707) 833-6979.
