Pyrographer Alissa O'Brien rescues discarded wood to create extraordinary works highlighting the grain patterns revealed beneath the bark. For this special event, Alissa will show the art of pyrography. Stop by the Visitor Center (10am-4pm, daily) to see Alissa's wood-burnings and for more information on the demonstration location. This program is free, but parking fees apply. On sunny days, holidays, and weekends, Walden Pond often closes due to capacity. If that happens, we will update DCR Park Alerts at mass.gov/park alerts and our phone message at 978-369-3254.
