[Traducido al español en los comentarios] What's Shakin' at Sugarloaf this weekend? The official start of summer means more time outside and you can mark the summer solstice with two new events. On Saturday, join CA Certified Naturalist John Lynch on a 5-mile guided nature hike with approximately 800 feet of elevation gain, looking up rather than down to learn about seasonal butterflies, dragonflies and wildflowers. On Sunday, take a quiet walk with Soundscape Ecologist Jack Hines to listen to the forest settle in Sunday evening.

New volunteers are welcome at our monthly Trail Crew Saturday. Learn trail restoration skills and meet others who want to give back to the park we love.

Saturday's Creekside Nature Hike is suitable for all ages and is a great way to explore Sugarloaf—no need to sign up, just show up at the Visitor Center at 10:00 am.

This year, make fourth of July plans that make an impact and join us for peace, serenity, and stargazing on Bald Mountain! Together, we'll hike 1.5 hours to the summit where we'll enjoy tasty treats, some stargazing courtesy of Robert Ferguson Observatory and their state-of-the-art telescopes, and settle in for a one-of-a-kind fireworks show, minus the busy crowds.

At 2,729 feet, Bald Mountain is one of the tallest peaks in Sonoma County, and on a clear July night, you can see fireworks going off across Sonoma, Napa, Marin, and Alameda counties all at the same time. It's pretty spectacular.

The impact? Sugarloaf Ridge State Park may be a California State Park, but it’s kept open and thriving by you—our community of visitors, donors, and volunteers. When you buy a ticket for our Fourth of July Hike, you help us strengthen community ties, fuel innovative outreach, and empower a passionate volunteer base—ensuring Sugarloaf Ridge State Park remains a place of discovery, well-being, and shared stewardship for generations to come.

The Fourth of July Hike is a win-win—a bucket-list Sonoma County experience and an investment in your local state park, all in the same evening. Tickets always sell out, so head to the link below to get yours!

Spotted on our last Full Moon Hike—a California Pink Glowworm (Microphotus angustus)! Typically found in oak woodlands and chaparral, this native California firefly is still a rare treat to spot on the trail—and a great reason to join one of our night hikes! The females are larviform, meaning they retain their larval form as adults. Flightless, the females emit a steady, brilliant neon-green light from the ground to attract flying, non-glowing males.

Have you spotted a California Pink Glowworm at Sugarloaf before? Let us know in the comments!
