Locals can work off the turkey and stuffing after Thanksgiving at one of the East Bay’s 73 regional parks that will be open and free to the public as part of “Green Friday.”

The East Bay Regional Park District will waive all entrance and park use fees on Friday — including parking, boat launching and fishing, in addition to access to Ardenwood Historic Farm — as an alternative to Black Friday shopping.

“Green Friday is a healthy and meaningful way to spend the day after Thanksgiving,” East Bay Parks Volunteer Program Supervisor Jessica Sloan said in a press release. “It’s a chance to enjoy time with family and friends in the outdoors or give back by participating in one of our volunteer clean-up projects.”

Green Friday activities at East Bay regional parks include:

• Volunteer Planting Opportunity, 9 a.m. at Contra Loma in Antioch (registration requested)
• Green Friday Hike Amongst the Trees, 9 a.m. at Reinhardt Redwood in Oakland
• Green Friday Hike, 9 a.m. at Black Diamond Mines in Antioch
• Green Friday Gratitude Hike, 10 a.m. at Sunol Wilderness in Sunol
• Green Friday Hike, 10:30 a.m. at Coyote Hills in Fremont

“However you choose to spend it, the day is all about celebrating and caring for our natural spaces,” Sloan said.
