ALCATRAZ HISTORIC GARDENS
Join us to help to remove invasive species that have overwhelmed the site and revegetate the garden with a mix of native species and horticultural species that were planted by the residents over 100 years ago! Activities primarily include weeding, pruning, and planting.
Wednesdays & Thursdays, 8 am - 12 pm

BLACK POINT HISTORIC GARDENS
Join us in caring for the restored gardens with activities such as weeding, pruning, composting, planting, propagating, and seed collecting. As an added bonus, garden volunteers arrive on Alcatraz before other visitors, so you can experience the island during the most tranquil time of day.
Thursdays, 2 - 5 pm
Fridays, 9 am - 12 pm
1st Saturdays, 10am - 1pm
