Come celebrate Halloween on the trails of Black Diamond Mines Regional Preserve — costumes are optional but encouraged! Our route takes us to the old Rose Hill Cemetery and beyond; among the rocks and vegetation, look for signs of the mining activities that occurred here more than 100 years ago.
Be sure to bring plenty of water, a snack, and dress in layers. Sturdy shoes or hiking boots are recommended. Heavy rain cancels.
Due to COVID-19, we are limiting the hike to 8 participants. All participants must bring a mask and stay 6ft apart. Hand sanitizer will be available at the hike.
Participants will also be required to accept our COVID-19 Protocol (available during registration).
