DAMARISCOTTA PUMPKINFEST & REGATTA

Pumpkins will take over downtown Damariscotta this weekend as the Damariscotta Pumpkinfest & Regatta returns for Indigenous Peoples’ Day weekend.

During the festival, set for Oct. 9-12, enormous pumpkins grown by local and regional growers are transformed into works of art and displayed throughout downtown and neighboring Newcastle. The volunteer-run festival is free and includes a pumpkin parade, pumpkin derby, children’s activities, food, street performers, contests and other events.

The signature event arrives Sunda when the Pumpkinboat Regatta takes to the Damariscotta River from noon to 2 p.m. Competitors climb inside hollowed-out giant pumpkins — some weighing hundreds of pounds — and race them in paddle and motorized divisions.

Other weekend highlights include the Pumpkin Parade from 2-4 p.m. Saturday; the Pumpkin Derby Sunday morning; and a pie-eating contest Sunday afternoon. The celebration continues Monday with the Tour de Gourd 5K, a children’s pumpkin hunt and the popular Pumpkin Drop, in which a giant pumpkin is hoisted high into the air before being dropped.
