The Sanbornton Blueberry Festival is a free annual summer festival at Keenan Family Farm in the New Hampshire Lakes Region, pairing pick-your-own blueberries with an artisan and craft market. Visitors shop handmade pottery, hand-crafted furniture, local honey, and jams from area vendors, grab treats from a bakery food truck, and enjoy family activities like face painting. Admission is free; pick-your-own blueberries run about $4/lb. (2026 date estimated from the festival's recurring late-July Saturday pattern — verify with organizer.)
